Connect
Connect Codex 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 Codex to:
Send that email instead of drafting itCreate that issue instead of describing itPost that message instead of suggesting itUpdate 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
2. Set Environment Variable export COMPOSIO_API_KEY="your-key"
3. Install pip install composio
npm install @composio/core
Done. Codex 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 Codex to do somethingTool Router finds the right tool (1000+ options)OAuth handled automaticallyAction 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 To send emails, I need Gmail access.
Authorize here: https://...
Say "connected" when done.
Connection persists after that.

Troubleshooting
Auth required → Click link, authorize, say "connected"Action failed → Check permissions in target appTool not found → Be specific: "Slack #general" not "send message"
