mcpgram-mcp-server

Official MCP server for MCPGRAM — stdio + Streamable HTTP + built-in OAuth 2.1 for Claude.ai, Cursor, and other MCP clients.

Features

• MCPGRAM as Authorization Server — DCR, PKCE, authorize, token, revoke

• Per-user workspaces — consent selects a workspace; tokens bind to that workspace API key

• No external Auth0 / WorkOS / Clerk dependency for MCP OAuth

Flow

Claude → discovery (PRM + AS metadata on this host)
      → POST /register (DCR)
      → GET /authorize (login + workspace + consent)
      → POST /token (code + PKCE)
      → POST /mcp (Bearer access token)
      → workspace tools

Environment

Claude connector URL

https://mcpgram-mcp-server.vercel.app/mcp

Claude will discover OAuth on this same origin (/register, /authorize, /token).

Isolation

Each user’s OAuth token only carries their selected workspace API key. User A never loads User B’s tools.
