Connecting the MCP

Setup is two steps: create an API key, then plug it into your MCP client.

Managing keys

List your keys in Settings, then API keys.
Revoke a key to deactivate it immediately. Clients using it receive a 401 Unauthorized.
Expiration is optional. Set it when creating a key if you want automatic rotation.

Symptom	Likely cause
`401 Invalid or expired API key`	The key was revoked, expired, or typed incorrectly. Create a fresh one.
`403` on a data tool	The chosen website has no active subscription, or you lack access to it.
Tools do not appear in Claude	Confirm the client restarted after editing the config, and the transport is `http`, not `sse`.

See the tools reference for what you can ask once connected.
