Common Room MCP endpoint and transport

Transport: Streamable HTTP
Docs: Official Common Room MCP docs

Connect Common Room without code

Common Room's docs confirm it works in Claude and ChatGPT. You don't need a terminal or a config file. Check Common Room's docs first: some vendors give you a personal URL or an API key to use in place of the plain endpoint.

Claude (web and desktop app)

If Common Room shows up when you browse connectors in Claude, connect it from there instead. That skips steps 2 to 4.

In Claude, open Customize → Connectors.
Click + Add, then Add custom connector.
Name it “Common Room”, paste the server URL https://mcp.commonroom.io/mcp, and click Continue.
Review the sign-in settings Claude detected and click Add.
Click Connect and sign in to Common Room. Then ask Claude something like “What can the Common Room connector do?”

On Team and Enterprise plans, an Owner adds the connector first under Organization settings → Connectors → Add → Custom → Web. Each person then connects it from Customize → Connectors. Free plans can add one custom connector.

ChatGPT

If Common Room has its own plugin in ChatGPT's directory, install that instead.

Go to chatgpt.com/plugins.
Select +, then Add custom MCP server. If you don't see it, your plan or workspace settings may not allow custom servers, so ask your workspace admin.
Enter a name and description. Under Connection, paste the server URL https://mcp.commonroom.io/mcp.
Set up sign-in, read the warning, and select I understand and want to continue.
Select Create as a plugin. In a new chat, type @ and pick Common Room.

Steps from the OpenAI developer docs: developers.openai.com, checked 2026-10-16

From Common Room's docs: Claude: install from the connector directory (a Claude admin may need to install it at org level first). ChatGPT: official ChatGPT App; enable it per chat via the + menu; not on ChatGPT Free. Cursor: tools appear in Agent/Composer. GitHub Copilot: VS Code Agent mode only. Claude Code: via the Common Room Claude plugin in the Claude Code plugin marketplace.Source: commonroom.io, checked 2026-10-16

Developer setup (Claude Code, Cursor)

Add this to .mcp.json (Claude Code, project root) or ~/.cursor/mcp.json (Cursor). Remove the // comment line if your client requires strict JSON.

{
  "mcpServers": {
    "common-room": {
      "url": "https://mcp.commonroom.io/mcp"
    }
  }
}

Add the endpoint to your client config (above), or as a custom connector in Claude.
Complete the OAuth sign-in. In Claude Code, run /mcp and pick the server.
Test it with a prompt like: “List the tools the Common Room MCP server exposes.”
