Ask your AI assistant and get the cite back: add Passage Data to Claude, ChatGPT, Cursor, VS Code or Microsoft 365 Copilot. Free, no key.
The address to add: https://passage-data.com/mcp
Claude: Customize → Connectors → + Add → Add custom connector; paste the address; choose No sign in. The Free plan holds one custom connector.
ChatGPT (Plus, Pro, Business, Enterprise, Edu, on the web): Settings → Apps → Advanced settings → turn on Developer mode; then Create app, paste the address, no authentication.
Cursor: Add to Cursor(opens Cursor, which asks you to confirm)
VS Code (GitHub Copilot agent mode): Add to VS Code(opens VS Code, which asks you to confirm). On a work account (Copilot Business or Enterprise), your admin decides which MCP servers run; if this one doesn't, ask them to allow https://passage-data.com/mcp.
Microsoft 365 Copilot: someone in your IT who builds agents adds the address in Copilot Studio (the agent's Tools → Add a tool → New tool → Model Context Protocol; authentication None), then publishes the agent to Teams and Microsoft 365 Copilot.
Claude Code: claude mcp add --transport http passage-data https://passage-data.com/mcp
Then ask it, for example: “Which environmental limits apply in European Union? Cite each one.”
