Seller API coverage

Your seller business is bigger than listings and stockouts.

Kuudo exposes 341 Selling Partner API operations across 57 resource groups. Your AI can work across orders, shipping, finances, feeds and reports, as well as catalog and fulfillment. The published tool reference lets your team check the specific operations a workflow needs.5

Orders and shipping

Read orders and order details, then work with Amazon Shipping and merchant fulfillment operations.5

Finances and reconciliation

Read transactions, balances and summaries; work with invoices and settlement reports.5

Feeds and reports

Create feed documents, submit feeds and request reports for repeatable account operations.5

Listings and A+ Content

Read and patch listing items, check restrictions, and create A+ Content documents.5

Inventory and fulfillment

Check FBA inventory, build inbound plans, and work with outbound fulfillment and Amazon Warehousing and Distribution.5

Customer and account operations

Read available buyer messaging actions, request eligible reviews, and manage notification subscriptions.5

Amazon publishes seller workflows for analytics, stockouts, inbound shipments and listings, plus a finance month-end closer that reconciles a completed month without moving money. Those workflows are useful overlap. They are not an exhaustive connector tool inventory, so this page does not infer that an unlisted operation is unavailable. Kuudo’s difference is a published API operation catalog your team can inspect and combine into its own workflows.35

Operation and resource counts describe Kuudo’s catalog, including versioned API resources. They are not a count of business workflows or proof of access to every Amazon endpoint. Availability depends on your account permissions, marketplace and the API; writes follow your workspace policy.57

To put that seller access in your AI client, follow the guide to connect Amazon Seller Central to Claude or connect Amazon Seller Central to ChatGPT. Copy the private server URL from your Kuudo dashboard. In Claude, add the signed connector URL through Customize > Connectors. In ChatGPT, add your server as a custom app in Apps settings, then enable it in a chat. The guides cover credentials and plan requirements; account permissions determine what the AI can do.

Where Amazon Seller Assistant and Kuudo actually differ.

25 rows. The first 12 follow the seller assistant job step by step, starting with seller API coverage, then the example requests Amazon publishes for its plugin: what Amazon Seller Assistant does at each step and how Kuudo does it. Beyond a seller assistant, you get your Amazon Ads, Amazon Marketing Cloud, Vendor Central, image and video generation, ready-made and custom Playbooks, Amazon operating knowledge, your own data lake, and the AI clients you want to use. Each competitor cell links to the page it was checked against and the date.

Amazon Seller Assistant vs Kuudo: Seller Coverage: 25 criteria compared side by side
CriterionAmazon Seller AssistantKuudo
Seller API coverage, then overlapping seller jobs
Seller API coverage How much of my seller business can my AI work on?Amazon publishes seller skills for analytics, inventory, inbound shipments, listings, finance month-end reconciliation and account tasks. Its public skills repository is not an exhaustive connector tool inventory, so endpoint-level parity cannot be established from it.3341 Selling Partner API operations across 57 resource groups: orders, shipping, finances, feeds, reports, listings, inventory, fulfillment, messaging and more. Check the tool reference for the operations your workflow needs; access depends on account permissions and API availability.5
Sales What were my sales last week?Amazon's help page for the plugin says the assistant "Returns your sales data for the requested period."2Sales_getOrderMetrics returns aggregated order metrics for an interval you set, broken down by granularity, through the Amazon Selling Partner MCP.5
Traffic How is my traffic trending over the last 8 weeks?Amazon's help page for the plugin says the assistant "Shows sessions, page views, and ordered units over time."2The Analyze Amazon Sales and Traffic Skill returns a portfolio and ASIN performance report with daily trends and anomalies, and separates traffic problems from conversion problems.12
Stockout risk Which of my ASINs are at risk of stocking out?Amazon's help page for the plugin says the assistant "Checks stock levels, days of supply, and demand forecasts."2Kuudo's Stockout Prevention Skill finds FBA SKUs at risk of stocking out from live FBA inventory and sales velocity, uses Amazon's own days of supply when available, ranks SKUs by risk, and checks whether inbound shipments land in time. It is read-only, and runs on FbaInventory_getInventorySummaries through the Amazon Selling Partner MCP.5
Listing errors Show me all my listings that have errors or are suppressed.Amazon's help page for the plugin says the assistant "Searches your listings filtered by status and flags issues."2ListingsItems_searchListingsItems searches for and returns your listings items and their details.5
Partial update Update the bullet points on a SKU without changing anything else.Amazon's help page for the plugin says the assistant "Proposes a partial update for your approval before taking action."2ListingsItems_patchListingsItem partially updates a listings item. It is a write tool, so it applies your workspace policy and may wait for your approval before the change reaches Amazon.5
Featured Offer price What price do I need to win the Featured Offer?Amazon's help page for the plugin says the assistant "Shows the Featured Offer expected price for your SKUs."2ProductPricing20220501_getFeaturedOfferExpectedPriceBatch returns Amazon's responses for a batch of up to 40 requests, through the Amazon Selling Partner MCP.5
Competition Show me the competitive landscape for an ASIN.Amazon's help page for the plugin says the assistant "Returns the Featured Offer, reference price, and lowest offers."2ProductPricing20220501_getCompetitiveSummary returns the competitive summary, including featured buying options for an ASIN and marketplace, and ProductPricing_getItemOffers returns the lowest priced offers for an ASIN.5
Fees Estimate the fees if I price this product at $29.99.Amazon's help page for the plugin says the assistant "Calculates referral and FBA fees at the price you specify."2Fees_getMyFeesEstimateForSKU and Fees_getMyFeesEstimateForASIN return the estimated fees for an item at the price in the request.5
Inbound plan Start an inbound plan for 400 units across 6 SKUs.Amazon's help page for the plugin says the assistant "Creates an FBA inbound plan and walks through packing, placement, and transportation."2Kuudo's FBA Inbound Skill runs the Fulfillment Inbound v2024-03-20 workflow end to end: build the inbound plan, pack, pick placement and carrier, confirm delivery windows, get labels and add tracking. It pauses at every fee-charging or irreversible step for your explicit choice, starting from FulfillmentInbound_createInboundPlan.5
Prep requirements What prep does Amazon require for these ASINs before I send them in?Amazon's help page for the plugin says the assistant "Returns prep and labeling requirements per ASIN."2FulfillmentInbound_listPrepDetails returns preparation details for a list of SKUs, and FulfillmentInboundV0_getPrepInstructions returns labeling requirements and item preparation instructions.5
Selling on Amazon How does the Subscribe and Save program work?Amazon's help page for the plugin says the assistant "Searches Amazon selling documentation and returns relevant guidance."2Agent Atlas is the reference layer your agent consults before it acts: it retrieves Amazon operating knowledge, and the agent is told to prefer retrieved playbooks over generic model knowledge and to say when the corpus does not support an answer.13
Beyond a seller assistant
Amazon Ads Can it run my Amazon Ads?Not published for the plugin. The announcement lists listing contributions, performance metrics, inventory and sales analytics as what the plugin connects. It says Seller Assistant can connect a product's performance "to an advertising or cross-promotion opportunity", and names no Amazon Ads account connection through the plugin.1756 Amazon Ads operations across Sponsored Products, Brands, Display, and TV, plus DSP, the unified Ads API v1, attribution, and reporting, through the Amazon Ads MCP.6
Amazon Marketing Cloud Can it query Amazon Marketing Cloud?Not published. The announcement and its list of what the plugin connects do not mention Amazon Marketing Cloud.1Yes. Amazon Marketing Cloud queries and audiences run through the Amazon Ads MCP.7
Vendor Central Can it run Vendor Central work?Not published. The announcement addresses sellers and says the plugin is in beta for sellers in Amazon's U.S. stores. It does not mention Vendor Central or vendors.142 Vendor Central operations: purchase orders and acknowledgements, direct fulfillment, shipments and invoices, transaction status, Retail Analytics, Data Kiosk, and A+ Content.7
Creative Can it generate listing and ad creative, images and video?Not published for the plugin. The announcement describes reading and acting on listings, performance, inventory and sales, and names no image or video generation through the plugin.1Yes. Agent Iris generates and audits listing images, and creates, edits, or extends owned product videos with Google Gemini Omni. Approved images publish through the Selling Partner MCP with ingestion checks; video assembly and final upload remain external.14
Playbooks Does it come with playbooks, and can I write my own?Seller Assistant Workflows. The announcement says "Sellers describe what they need in plain language, set guardrails, and the workflow goes to work", starting from prebuilt templates that "monitor account health, summarize orders, analyze pricing trends" or from scratch. Running a workflow through the plugin in Quick or Claude, and exporting one, are not published.120 Skills (2 Kuudo-certified) span Amazon Ads, Amazon Marketing Cloud, DSP, creative, profitability and seller jobs. Each states the job, the inputs, the outputs and what it is not for, and you can write your own in the same format.12
Operating knowledge Does it bring Amazon know-how to the job?Twelve skills and three commands for the plugin, published as readable SKILL.md files under Apache-2.0, each with an eval set: seller analytics, finance month-end reconciliation, stockout prevention, FBA inbound management, five listing skills, inviting secondary users, support cases, and Selling Partner API knowledge, which answers developer questions "grounded in the SP-API documentation".3Agent Atlas supplies curated Amazon operating playbooks and rules that your agent retrieves before it acts.13
Your data Where does your account data end up?To your AI client, outside Amazon. The help page says the account and related data "is sent to and processed on systems outside of Amazon's control, subject to your AI assistant's terms of service and privacy policy. Amazon is not responsible for how your AI assistant handles your data once accessed." An export, history store or warehouse sync is not published.2Agent Flow in Private Cloud lands your Ads and Selling Partner data in a data lake in your own cloud, on schedules you set, and Snowflake, Athena, DuckDB, Databricks, Power BI, and Tableau can read it downstream.11
Where you use it Which apps can I use it from?"We are launching the Amazon Selling Partner plugin in Quick and in beta with Claude, with more integrations to follow." The announcement says Seller Assistant's memory "follows sellers wherever they work—whether in Seller Central, Amazon Quick, or Claude", and adds: "Our vision is that sellers can use the AI agent of their choice to help them run their business, and we will make it easy for them to do so."1Claude, ChatGPT, Cursor, Copilot, n8n, or any MCP client.9
How it runs, and how you buy it
Where it runs Where does it run?Amazon's own endpoint: the toolkit README registers the Amazon Selling Partner Connector (MCP) at sellingpartner-ai.amazon.com/mcp. A self-hosted option is not published.3Choose Managed MCP, operated by Kuudo, or Private Cloud in your own cloud account. In Private Cloud, the DPA describes direct connections to your resources and Amazon; confirm the current Managed MCP data-handling terms with Kuudo.815
Approval What happens before anything changes on Amazon?Seller Central's help page for the plugin says "Actions require approval by default" and "You can limit the assistant to answers only." It adds: "You are responsible for all actions taken by the agent, whether or not you directly initiated them."2Write tools validate input, apply your workspace policy, and may require explicit human approval before a change reaches Amazon. Every tool call records the user, agent, parameters, result summary and approval state in a run log.7
Pricing model How is it priced?No price for the plugin is published. On the Amazon Quick route, AWS lists Quick Plus at "$20 / user / month billed annually; $25 / user/ month billed monthly", so each person who signs in is a seat.4Kuudo Community (Private Cloud) is free for one instance of each Amazon MCP server in your own cloud. Kuudo Pro (Private Cloud) is $0 a month plus $0.95 per 1,000 Amazon API calls, and Kuudo Scale (Private Cloud) is $249 a month plus $0.55 per 1,000 Amazon API calls, with seats included in each plan. The calculator models a month for a brand owner, an agency or aggregator, and an automation-heavy seller.10
Seats and organizations How many people and accounts?Per seller account and per user. The help page says "By default, account owners and administrators can authorize the plugin", through the account's Manage Agents page, and requires an "Amazon selling account on a Professional selling plan". An agency or partner model is not published.2Kuudo Pro (Private Cloud): up to 25 seats across 5 organizations. Kuudo Scale (Private Cloud): up to 50 seats across 10 organizations. Enterprise: unlimited.9
Free tier Can I try it free?A launch offer. The help page says: "Connect with Amazon Quick to get a free Quick Plus subscription. Primary sellers get 1 year free (up to $720 value). Other sellers get 30 days free. This offer is available through December 31, 2026."2Kuudo Community (Private Cloud) includes 10,000 free Amazon API calls per month, with one instance of each Amazon MCP server in your own cloud.9

Their fit

Choose Amazon Seller Assistant if

Real situations where Amazon Seller Assistant is the better buy. If one of them is yours, buy it.

  • You want Amazon Quick Plus free for a year, alongside the plugin.

    Amazon's help page says primary sellers who connect with Amazon Quick get a year of Quick Plus free, which it values at up to $720, and other sellers get 30 days, through December 31, 2026. AWS lists Quick Plus at $20 per user per month billed annually. Amazon names no price for the plugin itself, and Claude is the other way in. If Quick is where your team will work, the offer covers its first year.

  • Amazon's own tools have served you well, and you want its AI to work the same way.

    If Seller Central's reports, dashboards and recommendations have been enough, Seller Assistant carries that same approach into AI. Amazon builds the assistant and writes its skills, its workflows start from Amazon's templates, and the announcement says its memory follows you from Seller Central into Amazon Quick and Claude. If Amazon's way of running the business is the way you want to run it, the assistant Amazon built fits.

  • You want Amazon to set the scope: which tools, which AI, and when.

    The plugin is Amazon's own: it runs on Amazon's endpoint, sign-in is the Seller Central consent flow, and the assistant "can only use tools allowed by your Seller Central roles", per Amazon's toolkit README. Amazon chooses what it covers and when it grows, and the announcement says more integrations will follow. If a scope the marketplace operator sets and maintains is the assurance you want, it is Amazon's to give.

Our fit

Choose Kuudo if

Where Kuudo is the better buy. Amazon's plugin brings your seller data to the AI clients Amazon has integrated. Kuudo brings Amazon's own operations for the whole job to the AI client you choose, through Managed MCP or Private Cloud. Beyond a seller assistant, you get your Amazon Ads, Amazon Marketing Cloud, Vendor Central, image and video generation, ready-made and custom Playbooks, Amazon operating knowledge, your own data lake, and the AI clients you want to use.

  • The whole Amazon job

    You want orders, shipping, finances and reports in one AI, with Amazon Ads and Vendor Central beside them.

    Kuudo’s 341 Selling Partner API operations span 57 resource groups. Build seller workflows across orders, shipping, finances, feeds, reports, listings, inventory and fulfillment, using the published operation catalog to check the exact steps. Amazon’s public seller workflows overlap several of those jobs, including finance reconciliation, but its complete connector catalog is not published. Beyond seller work, the same AI reaches 756 Amazon Ads operations including Amazon Marketing Cloud, and 42 Vendor Central operations.

  • Your AI client

    Your AI should move at the pace of AI, not at the pace Amazon sets.

    Amazon's announcement says it well: "Our vision is that sellers can use the AI agent of their choice to help them run their business, and we will make it easy for them to do so." Amazon still decides the rest: its plugin runs in Amazon Quick and, in beta, Claude, for sellers in its U.S. stores as access rolls out, with the tools Amazon's connector allows and the skills Amazon writes. Kuudo is a platform built for the pace AI moves at. It connects Claude, ChatGPT, Cursor, Copilot, n8n or any MCP client to Amazon's own operations across ads, seller and vendor work, so when a better model, client or workflow ships, your team uses it on your schedule, not Amazon's.

  • Your rules

    Your AI should be able to question Amazon's answer with the rest of your business.

    Amazon's assistant works from Amazon's seller data, with skills Amazon writes, and its Workflows let you add plain-language guardrails. Good decisions often come from pushing back: test a recommendation against your own history, check a restock number against your margin and ad spend, ask what a report leaves out. That takes data Amazon has not published for its plugin: your history in your own data lake, Amazon Ads, Amazon Marketing Cloud and Vendor Central. Kuudo's 20 Skills (2 Kuudo-certified) are one of the most comprehensive public Amazon Skill collections, across that whole job, and you write your own in the same format. Your team's judgment runs beside Amazon's data, not under it.

  • Ownership

    The deployment, the data and the history should be yours.

    Choose Managed MCP or Private Cloud. In Private Cloud, your AI client connects to your cloud, which connects to Amazon, and the DPA describes the routing boundary. Agent Flow in Private Cloud keeps history in your Private Cloud lake for your warehouse and BI tools. Amazon's help page says plugin data is processed outside Amazon's control under your AI assistant's terms, and it publishes no export or warehouse for it. Private. Trusted. Owned.

  • Control

    What the AI may do is a policy you wrote, with a record you can read back.

    This one is close. Amazon's help page says plugin actions require approval by default and the assistant can be limited to answers only, and its announcement names complete audit trails. Kuudo's write tools validate input, apply the workspace policy you set, and may require a person's approval, and every call is recorded with the user, agent, parameters and approval state in one run log across the ads, seller and vendor servers. How much you automate, and who does the work, is your call.

The differences that matter

5 questions that decide Amazon Seller Assistant vs Kuudo.

Each one opens with the answer, then what each product does, then what it means for the person doing the work.

Can I use Amazon's Selling Partner plugin from ChatGPT?

Amazon has not published a ChatGPT integration. It launched the plugin in Amazon Quick and, in beta, Claude, with more integrations to follow. Kuudo connects ChatGPT, Claude, Cursor, Copilot, n8n or any MCP client to Amazon.

Amazon Seller Assistant

"We are launching the Amazon Selling Partner plugin in Quick and in beta with Claude, with more integrations to follow." The announcement names no other AI client.

Kuudo

Claude, ChatGPT, Cursor, Copilot, n8n, or any MCP client, connected through Managed MCP or Private Cloud.

What it means for you. If your team works in Claude, both products reach it there. If it works in ChatGPT, Cursor or an automation tool, Amazon has not published a plugin for it, and Kuudo connects it now.

MCP client configuration

How broad is Kuudo’s Selling Partner API coverage?

Kuudo publishes 341 seller operations across 57 API resource groups. That includes orders, shipping, finances, feeds, reports, listings, inventory and fulfillment. Your AI can combine those operations into seller workflows instead of starting from a short list of example prompts.

Amazon Seller Assistant

Amazon’s published workflows include sales analytics, stockout prevention, FBA inbound work, listing fixes and finance month-end reconciliation. Its full connector tool catalog is not published; an absent example does not establish an absent capability.

Kuudo

The tool reference lists operations individually, including their API resource and read or write status. Check the steps your workflow needs, then confirm account roles and marketplace availability. Your workspace policy governs writes.

What it means for you. Evaluate the whole seller workflow you want to run. A sales answer or listing fix is one job; orders, finance, feeds and fulfillment are also part of the buying decision, even if you only connect your seller account.

Inspect the Selling Partner API tool catalog

What does Amazon's plugin cost next to Kuudo?

Amazon publishes no price for the plugin. The Amazon Quick route is priced per person, with a free Quick Plus year for primary sellers through December 31, 2026. Kuudo Private Cloud is priced by Amazon API call, with seats included in each plan.

Amazon Seller Assistant

No plugin price is published. AWS lists Quick Plus at $20 per user per month billed annually or $25 billed monthly. Amazon's launch offer gives primary sellers who connect with Quick a year of Quick Plus free, up to a $720 value, and other sellers 30 days, through December 31, 2026.

Kuudo

Kuudo Community (Private Cloud) is free. Kuudo Pro (Private Cloud) is $0 a month plus $0.95 per 1,000 Amazon API calls with up to 25 seats across 5 organizations, and Kuudo Scale (Private Cloud) is $249 a month plus $0.55 per 1,000 Amazon API calls with up to 50 seats across 10.

What it means for you. If your team works in Claude, its Claude plan costs the same with either product. The difference is on the Quick route, which is priced per person, and on accounts: Amazon authorizes per seller account and per user, while one Kuudo plan covers several organizations.

Kuudo pricing

What happens before the AI changes my Amazon account?

Both can make a write wait for a person. Amazon's plugin requires approval by default and can be limited to answers only. Kuudo's write tools apply the workspace policy you set, which decides when a person must approve, and record every call in a run log.

Amazon Seller Assistant

"Actions require approval by default" and "You can limit the assistant to answers only", per the help page, and the announcement says every plugin interaction has "human approval on actions, and complete audit trails." The help page adds that you are responsible for every action the agent takes.

Kuudo

Write tools validate input, apply your workspace policy, and may require explicit human approval before a change reaches Amazon, and every call is recorded with its parameters and approval state in a run log.

What it means for you. This row is close to even. The difference is reach: Kuudo's policy and run log span the ads, seller and vendor servers, so one record covers the whole job.

Read and write tools

Where does my Amazon data go, and what history do I keep?

With either, what the AI reads goes to your AI client. Amazon's help page says that data is processed outside Amazon's control, and it publishes no export or history store. Kuudo's Agent Flow in Private Cloud keeps the history in a data lake in your own cloud.

Amazon Seller Assistant

The account and related data "is sent to and processed on systems outside of Amazon's control, subject to your AI assistant's terms of service and privacy policy", per the help page. An export, history store or warehouse sync is not published.

Kuudo

Agent Flow in Private Cloud lands your Ads and Selling Partner data in a data lake in your own cloud on schedules you set, and your warehouse and BI tools read it downstream.

What it means for you. Live reads answer today's question. Owned history answers next quarter's, and it stays in your account if you change tools.

Amazon Agent Flow documentation

Running both

Pick one connection for the seller account.

You can add both to Claude, because MCP clients hold several connections at once. We would not run both on the same seller account: two connections that can write mean two approval paths and two records for the same changes. Choose Amazon when its published seller workflows fit your work. Choose Kuudo when you want to assemble seller workflows from its published API catalog, or bring ads, Amazon Marketing Cloud and Vendor Central into the same AI client.

What we could not verify

  • The connector's full tool catalog is not published; Amazon's public skills repo shows the skills, not the catalog. No cell on this page infers what the plugin can or cannot do from what the skills call.
  • Whether the plugin reaches Amazon Ads, Amazon Marketing Cloud or Vendor Central data: Amazon's pages describe seller data and publish none of the three, so the cells say not published rather than not offered.
  • The price of the plugin itself: Amazon's pages offer a free Amazon Quick Plus year and name no price for the plugin. Whether the plugin works on Amazon Quick's free plan is not published.
  • Whether one AI client can connect several seller accounts, which matters to agencies: not published.
  • Where a seller reads the plugin's audit trail: the announcement names complete audit trails and does not say where they appear.
  • Amazon's help page for the plugin is readable only when signed in to Seller Central; its wording on this page was read signed in on 2026-09-26.

Frequently asked questions

Questions sellers ask before choosing between Amazon Seller Assistant and Kuudo.

What the selling partner plugin for AI assistants is, which AI clients and Amazon jobs each one reaches, agencies and several accounts, your data, and what each costs.

Is the Amazon Seller Assistant plugin for Claude any good, and what are the alternatives?
It is a good fit for seller operations inside Amazon's own assistant, in Seller Central, Amazon Quick or Claude, with a free year of Amazon Quick Plus on offer. For one AI that runs Amazon Ads, Amazon Marketing Cloud, Vendor Central and seller work from the client you choose, with Managed MCP or Private Cloud, and optional Agent Flow history in your own cloud, the alternative is Kuudo. The rows on this page are how to decide.
What is Amazon's selling partner plugin for AI assistants?
It is Amazon's Seller Central plugin for Claude and Amazon Quick, which Amazon also calls the Seller Assistant plugin: it connects your Amazon seller data and Seller Assistant to an outside AI client, so you can ask about sales, inventory, traffic and listings without returning to Seller Central. Amazon launched it on September 23, 2026 in Amazon Quick and, in beta, Claude, for sellers in Amazon's U.S. stores on a Professional selling plan. Amazon's toolkit README calls it the Amazon Selling Partner Connector (MCP), and Amazon publishes twelve readable skills for it on GitHub.
Does Amazon's Selling Partner plugin work with ChatGPT, or outside the U.S.?
Not yet. Amazon names Amazon Quick and, in beta, Claude, with more integrations to follow, and publishes no ChatGPT integration. The plugin is a beta for sellers in Amazon's U.S. stores, with international expansion to follow; Seller Assistant inside Seller Central has rolled out to over 90% of selling partners worldwide. Kuudo connects ChatGPT, Claude, Cursor, Copilot, n8n or any MCP client to Amazon's own operations in every marketplace your accounts reach, across North America, Europe and Asia-Pacific.
Can Amazon's Selling Partner plugin manage my Amazon Ads campaigns or Amazon Marketing Cloud?
Amazon has not published that it does. Its announcement lists listing contributions, performance metrics, inventory and sales analytics as what the plugin connects. Kuudo runs Amazon Ads through the Amazon Ads MCP, Amazon Marketing Cloud queries and audiences through the same server, and Vendor Central through its own MCP server, beside seller operations.
Can an agency connect several seller accounts?
Amazon publishes no agency or partner model for the plugin. It is authorized per seller account and per user: by default, account owners and administrators authorize it through that account's Manage Agents page. Kuudo Pro (Private Cloud) covers up to 25 seats across 5 organizations and Kuudo Scale (Private Cloud) up to 50 seats across 10, priced by Amazon API call.
Where does my data go, and can I keep the history?
With either one, what the AI reads goes to your AI client. Amazon's help page says plugin data is processed outside Amazon's control under your AI assistant's terms, and Amazon publishes no export or history store for it. Kuudo offers Managed MCP or Private Cloud. In Private Cloud, Agent Flow keeps your Ads and Selling Partner history in a data lake you own. Confirm Managed MCP data-handling terms with the team.
What does each one cost?
Amazon names no price for the plugin. On the Amazon Quick route, AWS lists Quick Plus at $20 per user per month billed annually, and Amazon's launch offer gives primary sellers a free year and other sellers 30 days, through December 31, 2026. In Claude, your Claude plan costs the same with either product. Kuudo Community (Private Cloud) is free for one instance of each Amazon MCP server in your own cloud; Kuudo Pro (Private Cloud) and Scale are priced per 1,000 Amazon API calls.
