Summary
Turns Claude from a text generator into something that actually executes actions across 1000+ apps. Instead of getting draft emails or suggested Slack messages, it sends them. Built on Composio's tool router, which handles OAuth and finds the right integration whether you're creating GitHub issues, updating Notion databases, or posting to Discord. The auth flow is straightforward: first time you use an app, you get a link to authorize, then connections persist. Works with any MCP client, plus they have dedicated packages for popular frameworks. The pitch is simple and honestly kind of compelling: stop generating text about what could happen and just make it happen.

Connect
Connect Claude to any app. Stop generating text about what you could do - actually do it.
When to Use This Skill
Use this skill when you need Claude to:
- Send that email instead of drafting it
- Create that issue instead of describing it
- Post that message instead of suggesting it
- Update that database instead of explaining how
What Changes
| 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 |

Setup
1. Get API Key
Get your free key at platform.composio.dev
2. Set Environment Variable
export COMPOSIO_API_KEY="your-key"
3. Install
pip install composio # Python
npm install @composio/core # TypeScript
Done. Claude can now connect to any app.
Examples
Send Email
Email sarah@acme.com - Subject: "Shipped!" Body: "v2.0 is live, let me know if issues"
Create GitHub Issue
Create issue in my-org/repo: "Mobile timeout bug" with label:bug
Post to Slack

Chain Actions
Find GitHub issues labeled "bug" from this week, summarize, post to #bugs on Slack
How It Works
Uses Composio Tool Router:
- You ask Claude to do something
- Tool Router finds the right tool (1000+ options)
- OAuth handled automatically
- Action executes and returns result
Code
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!")
Auth Flow
First time using an app:
To send emails, I need Gmail access.
Authorize here: https://...
Say "connected" when done.
Connection persists after that.
Framework Support
| Framework | Install |
|---|---|
| Claude Agent SDK | pip install composio claude-agent-sdk |
| OpenAI Agents | pip install composio openai-agents |
| Vercel AI | npm install @composio/core @composio/vercel |
| LangChain | pip install composio-langchain |
| Any MCP Client | Use session.mcp.url |
Troubleshooting
- Auth required → Click link, authorize, say "connected"
- Action failed → Check permissions in target app
- Tool not found → Be specific: "Slack #general" not "send message"
