Common Room MCP connects agents to an authorized Common Room instance for community and GTM intelligence. Use it to surface member signals, conversations, and trends for go-to-market insights.

5 Tools

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Common Room account to Claude via Composio Connect, enabling it to summarize top community threads this week, list highly engaged members last 30 days, create segment of churn-risk community members, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Common Room account

Back in Claude, ask it to connect to Common Room or give it any Common Room-related task.

For example, ask Claude to:

  • "Summarize top community threads this week"
  • "List highly engaged members last 30 days"
  • "Create segment of churn-risk community members"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Common Room account is ready to use.

What is the Common Room Claude Connector, and what's possible with it?

The Common Room MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Common Room account. It provides structured and secure access so your agent can perform Common Room operations on your behalf.

Troubleshooting

1. Why does Claude not use the Composio connector for Common Room?

The connector can show as connected, but Claude must use it in each Common Room conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Common Room again.

2. Why does Claude show an MCP server error before Common Room connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Common Room.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Common Room.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Common Room authorization link not work?

The Composio connector is one server. Your Common Room account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Common Room connection.
  • Composio creates a fresh Common Room authorization link.
  • Open that link in your browser and finish the Common Room sign-in.

4. Why do Common Room actions fail after they worked before?

The Common Room connection can expire or lose permission.

  • Ask Claude to inspect the Common Room connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Common Room account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Common Room.
  • If the action still fails with a permission error, check that the connected account has that permission in Common Room itself.

5. How do I switch to a different Common Room account?

Claude can manage the Common Room connection for you.

  • Ask Claude to disconnect or delete the current Common Room account.
  • Ask Claude to connect Common Room again.
  • Open the new Composio authorization link for Common Room.
  • Sign in with the other Common Room account in the browser.
  • After the account connects, ask Claude to retry the Common Room task.

6. Why is my Common Room connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Common Room connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Common Room tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Common Room.

FAQ

Frequently asked questions

With a standalone Common Room MCP server, the agents and LLMs can only access a fixed set of Common Room tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Common Room and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Common Room tools.

Yes, absolutely. You can configure which Common Room scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Common Room data and credentials are handled as safely as possible.
