Connect Claude to external apps through Composio to send emails, create issues, post messages, and update data. It also supports linked tasks, such as summarizing GitHub issues and posting the results to Slack.
Connect Claude to any app. Send emails, create issues, post messages, update databases - take real actions across Gmail, Slack, GitHub, Notion, and 1000+ services.
This skill connects Claude to external apps to send emails, create issues, post messages, and update data. Composio Tool Router selects a tool that matches your request, handles authentication, and returns the result of the action. The introduction covers connections to Gmail, Slack, GitHub, and Notion, as well as sequences of work that span multiple apps.
Use it when you have decided what an email or post should say and want Claude to send it. It also helps combine information gathering with communication, such as checking GitHub issues, summarizing them, and sharing the summary on Slack.
Obtain a Composio API key and set COMPOSIO_API_KEY. Installation instructions cover packages for Python or TypeScript. Each app requires access authorization on first use. Available actions depend on the permissions granted in the connected app.

Connect Claude to any app. Stop generating text about what you could do - actually do it.
Use this skill when you need Claude to:
| Without Connect | With Connect |
|---|---|
| "Here's a draft email..." | Sends the email |
| "You should create an issue..." | Creates the issue |
| "Post this to Slack..." | Posts it |
| "Add this to Notion..." | Adds it |
1000+ integrations including:
Get your free key at platform.composio.dev
export COMPOSIO_API_KEY="your-key"
pip install composio # Python
npm install @composio/core # TypeScript
Done. Claude can now connect to any app.
Email sarah@acme.com - Subject: "Shipped!" Body: "v2.0 is live, let me know if issues"
Create issue in my-org/repo: "Mobile timeout bug" with label:bug
Post to #engineering: "Deploy complete - v2.4.0 live"
Find GitHub issues labeled "bug" from this week, summarize, post to #bugs on Slack
Uses Composio Tool Router:
from composio import Composio
from claude_agent_sdk.client import ClaudeSDKClient
from claude_agent_sdk.types import ClaudeAgentOptions
import os
composio = Composio(api_key=os.environ["COMPOSIO_API_KEY"])
session = composio.create(user_id="user_123")
options = ClaudeAgentOptions(
system_prompt="You can take actions in external apps.",
mcp_servers={
"composio": {
"type": "http",
"url": session.mcp.url,
"headers": {"x-api-key": os.environ["COMPOSIO_API_KEY"]},
}
},
)
async with ClaudeSDKClient(options) as client:
await client.query("Send Slack message to #general: Hello!")
First time using an app:
To send emails, I need Gmail access.
Authorize here: https://...
Say "connected" when done.
Connection persists after that.
