For developers building a client that connects to the NanoCorp MCP server.

​
Endpoint and protocol

  • MCP endpoint: https://mcp.nanocorp.so, at the root path (/mcp is not served), streamable HTTP.
  • Protocol: every MCP revision from 2024-11-05 to 2026-07-28. On a revision older than 2026-07-28, start with initialize. The server keeps no session, so it sends no Mcp-Session-Id, and it answers GET with 405 because it opens no event stream. A request naming a revision the server does not know is refused with UnsupportedProtocolVersion (-32022).
  • Authentication: OAuth only. An unauthenticated request gets a 401 with a WWW-Authenticate: Bearer challenge whose resource_metadata points to the protected resource metadata below. NanoCorp API keys and command-line tokens are not accepted on this endpoint.

​
Discovery

The authorization server is https://accounts.nanocorp.so. Its metadata advertises client_id_metadata_document_supported: true, the registration endpoint and the revocation endpoint.
