  Test OAuth2 client_credentials authentication flows locally.

• 2

  A mock MCP streamable HTTP endpoint with token validation.

• 3

  Develop or debug LiteLLM proxy integrations with OAuth2 secured MCP servers.

Description

This server combines an OAuth2 token endpoint with an MCP Streamable HTTP endpoint, enabling testing of OAuth2 client_credentials (machine-to-machine) flows with the LiteLLM proxy. It supports bearer token validation to secure the MCP endpoint and includes a built-in echo tool for streamable HTTP transport. The server is easy to set up and run locally, facilitating development and testing of OAuth2 authenticated MCP interactions.
