API tokens (for AI assistants / MCP)

For long-running integrations — most importantly MCP clients like Claude, Cursor and VS Code — use a long-lived API token instead of the daily JWT. Generate one in your dashboard at /p/mcp-tokens and pass it as Authorization: Bearer <token>. The token is shown only once at creation time; revoke at any time from the same page.
