Superdata exposes a stateless Streamable HTTP MCP endpoint:

​
OAuth

Clients with MCP OAuth support can discover Superdata’s authorization server from the endpoint’s WWW-Authenticate challenge. Complete browser sign-in and grant the mcp:use permission.

​
API key

Create a key from Connections, then send it as a bearer token:
For raw HTTP calls, include both accepted result formats:
The account that owns the key and the key itself must remain active.
Never place the key in a URL, source file, screenshot, or chat message. Use an environment variable or your client’s secure credential storage.

​
Verify the connection

After the MCP initialization handshake, list tools. A working connection exposes direct superdata_* intelligence tools, interactive presentation tools, and the superdata_search_capabilities, superdata_get_capability, and superdata_call progressive fallback.
