About MCP PROXY SERVER
MCP PROXY SERVER is a proxy for operators who want to expose several MCP servers through one HTTP entrypoint. It aggregates tools, prompts, and resources, with multiple transport options and downstream OAuth handling.
Key features
- 01Aggregate tools, prompts, and resources
- 02Serve over SSE or streamable HTTP
- 03Configure stdio, SSE, and HTTP clients
- 04Authorize and refresh downstream OAuth tokens
Use cases
- 01Provide one HTTP entrypoint for multiple MCP servers
- 02Connect downstream servers that require interactive OAuth
MCP support
It aggregates downstream MCP servers and serves their tools, prompts, and resources to MCP clients over SSE or streamable HTTP.
Details
From the project READMEMCP Proxy Server
An MCP proxy that aggregates multiple MCP servers behind a single HTTP entrypoint.
Features
- Proxy multiple MCP clients: aggregate tools, prompts, and resources from many servers.
- SSE and streamable HTTP: serve via Server‑Sent Events or streamable HTTP.
- Flexible config: supports
stdio,sse, andstreamable-httpclient types. - OAuth client support: authorize once against downstream servers that require interactive OAuth (e.g. Notion), then let the proxy hold and refresh the token for every caller.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
