Replace the values in angle brackets with your own. Keys stay on your machine; we never see them.

Tools

This server asks for a key before it lists its tools. Connect it with your own key to see them.

Headers

NameDescription
x-api-key
Optional, secret		Index One team API key. Only needed by clients that cannot do OAuth; OAuth-capable clients (Claude connectors and similar) sign in with an Index One account instead and send no header. Create keys in the console under Team API Keys.
