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

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

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

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"
