Summary

Execute real actions across 1000+ apps instead of generating text about them.

  • Supports 1000+ integrations including Gmail, Slack, GitHub, Notion, Airtable, HubSpot, Salesforce, and cloud storage services
  • Handles OAuth authentication automatically on first use, with persistent connections thereafter
  • Works with Claude Agent SDK, OpenAI Agents, Vercel AI, LangChain, and any MCP-compatible client
  • Enables chaining multiple actions in sequence, such as querying GitHub issues, summarizing results, and posting to Slack
SKILL.md

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 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:

  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"
