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

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:bugPost to Slack
Post to #engineering: "Deploy complete - v2.4.0 live"Chain Actions
Find GitHub issues labeled "bug" from this week, summarize, post to #bugs on SlackHow 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"
