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

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

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"
