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

Supported Apps

1000+ integrations including:

• Email: Gmail, Outlook, SendGrid
• Chat: Slack, Discord, Teams, Telegram
• Dev: GitHub, GitLab, Jira, Linear
• Docs: Notion, Google Docs, Confluence
• Data: Sheets, Airtable, PostgreSQL
• CRM: HubSpot, Salesforce, Pipedrive
• Storage: Drive, Dropbox, S3
• Social: Twitter, LinkedIn, Reddit

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 [email protected] - 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:

1. You ask Claude to do something
2. Tool Router finds the right tool (1000+ options)
3. OAuth handled automatically
4. 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"
