Lets Claude, ChatGPT or Cursor use Gmail, Slack, GitHub and 1000+ other apps through one Composio sign-in.

This is Composio's own hosted server. You add one address to your assistant, sign in with your browser, and the assistant can find and use actions in 1000+ apps. It shows only 7 general tools and finds each app's actions on demand, so what it can do depends on the apps you connect. The first time an app is needed, you approve a sign-in link for it.

Good for

  • People who want one connection to many apps instead of one server per app
  • Teams that want the assistant to act across Gmail, Slack, GitHub and Linear in one request
  • Anyone who prefers browser sign-in over pasting keys into config files

Install Composio MCP

Claude Code

  1. 1

    Copy this prompt.

    Add the Composio MCP server to Claude Code. Run this command:

claude mcp add --transport http composio https://connect.composio.dev/mcp

Then check that it loaded and tell me if I need to sign in or restart.
  2. 2

    Paste it into Claude Code. It shows the change and asks before running it.

Requires Sign-in with the vendor account (OAuth).

Built from the package data we hold. Not yet tested by us.

Tools

  • Finds the right app actions for your request

    Takes what you ask for, looks it up in Composio's app catalog and hands back the matching actions plus a suggested order of steps.

    Try: “Find the tools I need to email my team a summary.”

    Network · COMPOSIO_SEARCH_TOOLS

  • Runs actions in your connected apps

    Performs the actions found by search, in parallel, in the apps you have connected. One call can carry up to 50 actions, and what they change depends on the apps.

    Try: “Send the summary by Gmail and post it in Slack.”

    Delete · COMPOSIO_MULTI_EXECUTE_TOOL

  • Connects, lists, renames or removes app links

    Handles your links to apps: creates a new one, lists the current ones, renames one or removes it. A new link gives you a browser approval page.

    Try: “Connect my GitHub account.”

    Delete · COMPOSIO_MANAGE_CONNECTIONS

  • Runs Python in a remote sandbox

    Executes Python on a Composio server instead of your computer, useful when a result is too big to read directly or a job needs many rows.

    Try: “Process these 500 rows and give me totals.”

    Runs code · COMPOSIO_REMOTE_WORKBENCH

  • Runs shell commands in a remote sandbox

    Executes shell commands on a Composio server instead of your computer, useful for unpacking, sorting or filtering big files.

    Try: “Unzip and sort this export in the sandbox.”

    Runs code · COMPOSIO_REMOTE_BASH_TOOL

  • Used by the assistant behind the scenes

    Fetches the inputs an app action needs

    Returns the full input details for tools found by search so the assistant can call them correctly.

    Network · COMPOSIO_GET_TOOL_SCHEMAS

  • Waits while you approve an app link

    Pauses the assistant until you finish the browser sign-in for an app.

    Network · COMPOSIO_WAIT_FOR_CONNECTIONS

Permissions

high risk · 4 things to watch

High risk

It can read, send, change and delete things in every app you connect, and your data passes through Composio's servers. Connect only the apps you need and check each action before you approve it.

What it can do

  • Read your data
  • Create and change things
  • Delete things
  • Read-only mode

Watch out for

  • It acts in every app you connect

    One tool runs actions in your connected apps, and the docs list no read-only mode. Connect only the apps you need, and review sends and deletes. docs.composio.dev

  • Your app data passes through Composio

    It is a hosted service, so requests and results go through Composio's servers. Check your company rules before connecting work accounts. github.com

  • It can run code in a remote sandbox

    Two tools run Python and shell commands on Composio's side for bulk work. They do not run on your computer. docs.composio.dev

  • A consumer API key works like a password

    Apps without OAuth use an API key header. Keep it out of repositories and chats. docs.composio.dev

Technical details
Talks toconnect.composio.dev (hosted by Composio). login.composio.dev for sign-in. Composio's remote sandbox for code and shell commands
Sign-in and keysYou sign in with Composio through OAuth, and each app is connected through its own OAuth approval kept by Composio. Clients without OAuth can use a consumer API key sent in a header.

Questions

Is this the official Composio MCP server?

Yes. It is Composio's own hosted server, listed in the official MCP registry under Composio's GitHub organization.

What is the Composio MCP server URL?

https://connect.composio.dev/mcp. The docs say to use this address and not a backend.composio.dev one.

Do I need an API key?

No for most apps. Connecting opens a Composio sign-in in your browser. Clients without OAuth support can use a consumer API key sent in a header, found in the Composio dashboard.

Does it run on my computer?

No. It is a hosted server, and nothing runs locally. Composio also offers a command-line tool and plugins for Claude Code and Codex, which its docs recommend for those agents.

Can I use it in ChatGPT?

Yes, with Developer mode on, which needs ChatGPT Plus, Pro, Business, Enterprise or Edu. You enable Composio again in each new chat.

Can I run it read-only?

No read-only mode is documented. Limit what it can do by connecting only the apps you need.

Why does it ask me to sign in again?

Links for connecting an app are short-lived. Ask the assistant to retry and it makes a fresh one. If an app action gives an auth error, ask it to reconnect that app.

Which tools does it have for my apps?

The server itself has 7 general tools. Actions for each app are found through search at the time you ask, so the list depends on what you connect.
