Free Amazon Seller MCP: No-Code Setup

1. Open claude.ai and go to Settings → Connectors.
2. Click Add custom connector.
3. Name it Porter and paste https://mcp.portermetrics.com/mcp.
4. Click Add, then sign in with your Porter account and approve access.
5. Ask “Connect my Amazon Seller account”, sign in with Amazon and approve Porter.
6. Ask Claude your first Amazon Seller question.

On Team and Enterprise plans, an owner adds the connector first. Anthropic’s custom connector guide covers the same steps. For a longer walkthrough, read how to connect Amazon Seller Central to Claude or see the Amazon Seller Central connector for Claude.

ChatGPT has two routes to the same data. The Porter Metrics app in ChatGPT’s app directory works on any plan with apps. The Porter MCP gets every new tool the day Porter ships it, on Business, Enterprise and Edu workspaces.

Porter Metrics app: in ChatGPT, open Apps, search “Porter Metrics”, click Connect and sign in with your Porter account, then ask “Connect my Amazon Seller account”, sign in with Amazon and approve Porter.

Porter MCP:

1. Open ChatGPT on the web and go to Plugins.
2. Click +, then Add custom MCP server.
3. Name it Porter and paste https://mcp.portermetrics.com/mcp under Connection.
4. Choose OAuth, tick “I understand and want to continue” and click Create as a plugin.
5. Sign in with your Porter account.

Pro accounts can add it with read access only, per OpenAI’s custom MCP server guide.

For the full guide, read how to connect Amazon Seller Central to ChatGPT or see the Amazon Seller Central connector for ChatGPT.

Pick your coding agent. Each one uses the same server URL and a Google sign-in, so no API key or credentials file sits in a config.

Claude CodeCuCursorVSVS CodeCodex

1. Add Porter’s plugin in Claude Code. It installs the Porter connector and Porter’s skill in one step.
   /plugin marketplace add portermetrics/porter /plugin install porter-metrics@portermetricsCopy
2. Ask for your data. The first time, your browser opens: sign in with the Google account you use in Porter.
3. No plugins? Add the server directly instead:
   claude mcp add --transport http porter https://mcp.portermetrics.com/mcpCopy
4. Check: /mcp shows porter as connected. Ask: “Which Amazon Seller accounts can you see?”

1. Open Cursor Settings → Tools & Integrations and click New MCP Server. Cursor opens mcp.json.
2. Paste this and save.
   { "mcpServers": { "porter": { "url": "https://mcp.portermetrics.com/mcp" } } }Copy
3. Click Connect next to porter and sign in with the Google account you use in Porter.
4. Check: porter shows a green dot in Tools & Integrations. Open an Agent chat. Ask: “Which Amazon Seller accounts can you see?”

1. Open the Command Palette (Ctrl/Cmd+Shift+P) and run MCP: Add Server → HTTP.
2. Paste https://mcp.portermetrics.com/mcp, name it porter and choose Global. Or add it to .vscode/mcp.json:
   { "servers": { "porter": { "type": "http", "url": "https://mcp.portermetrics.com/mcp" } } }Copy
3. Allow the sign-in prompt and sign in with the Google account you use in Porter.
4. Check: open Copilot Chat in Agent mode; Porter’s tools appear under the tools icon. Ask: “Which Amazon Seller accounts can you see?”

1. Add Porter from your terminal.
   codex mcp add porter --url https://mcp.portermetrics.com/mcpCopy
2. Sign in. Your browser opens: sign in with the Google account you use in Porter.
   codex mcp login porterCopy
3. Check: codex mcp list shows porter as logged in. Start codex. Ask: “Which Amazon Seller accounts can you see?”

The same URL works in Windsurf, Cline, Zed and any client that supports remote MCP servers over HTTP.

Porter’s skill teaches Claude which Porter tools to call for each Amazon Seller task, so answers need fewer retries. In claude.ai, download https://mcp.portermetrics.com/skill.zip and upload it in Settings → Capabilities → Skills. In Claude Code, Porter’s plugin adds it for you, and other agents can run npx skills add portermetrics/porter.

Paste this into a new chat. It only reads data.

Amazon ships Local MCP for SP-API, an npm package for developers who build SP-API integrations (Amazon’s announcement of Local MCP for SP-API). It runs on your own machine with Node.js 20 or newer. Live calls need your own SP-API client ID, client secret and refresh token, which means registering as an SP-API developer first (Amazon’s SP-API registration overview).

Porter’s video connects Amazon Seller Central to Claude through Porter, from the Amazon sign-in to the first sales question.

Your first question, in either client:
