Polystate in your AI
Add Polystate to ChatGPT, Claude, Cursor and other AI apps with one link. Residency, visas, crypto tax and company formation for about 170 countries, with sources and dates. No account, no key.
Your connector URL
https://polystate-mcp-server.shy-surf-2fdf.workers.dev/mcpSetup
Every app takes the same URL. Paste it, skip any sign-in step, and ask a question such as “Compare crypto tax in Portugal and Paraguay”.
Works in claude.ai and the Claude desktop app. The Free plan allows one custom connector.
Menu names differ between plans. On Business, Enterprise and Edu an admin may need to allow it first.
Le Chat detects that no sign-in is needed. Only workspace admins can add connectors.

}Good to know
The free connector has limits shared by everyone. If you build something that makes many calls, create a free API key and add it as a bearer token.
Answers carry the official link and the date the data was checked. Ask your AI to show them.
The data is indicative. Governments decide every application. To book a service, the connector sends you to polystate.io.
