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:
The account that owns the key must remain approved, and the key 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 superdata_search_companies and superdata_search_people.
