# Authsome MCP Proxy

A [Model Context Protocol](https://modelcontextprotocol.com) (MCP) proxy that
bridges *upstream MCP servers protected by token validation or static
credentials* to MCP clients such as Claude Desktop, Claude Code, Cursor,
Codex, MCP Inspector, and Claude.ai. ("Authsome" as in *awesome*, but with
auth.)

The proxy can run as:

- **Web connector** (`--transport http`, **recommended for end users**) —
  a persistent HTTP server that any MCP client reaches by URL. Downstream
  clients authenticate against the proxy via Dynamic Client Registration
  or a Client ID Metadata Document; the proxy bridges to your IdP and
  forwards traffic upstream. A single
  instance can serve many users simultaneously and lives behind a normal
  URL (`https://mcp.example.com/mcp`) — no per-user config files,
  subprocess launchers, or local Python toolchains. This is the default
  for non-developer rollouts and the only mode that works with web-only
  clients like Claude.ai.

- **Local stdio proxy** (`--transport stdio`, the default for backwards
  compatibility, **developer use**) — launched as a subprocess by the MCP
  client (Claude Desktop, Cursor, Codex, Claude Code via `claude mcp
  add --transport stdio`). Each user runs their own instance and the proxy
  performs the OAuth flow against an external OIDC IdP on their behalf.
  Useful when you don't have a server to host the proxy on or when the
  upstream MCP only validates tokens and you want each developer to
  authenticate locally.
