Create GitHub Issue

Create issue in my-org/repo: "Mobile timeout bug" with label:bug

Post 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 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

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"
