When to Apply
- User wants to access or interact with external apps (Gmail, Slack, GitHub, Notion, etc.)
- User wants to automate a task using an external service (send email, create issue, post message)
- Building an AI agent or app that integrates with external tools
- Multi-user apps that need per-user connections to external services
Setup
Check if the CLI is installed; if not, install it:
curl -fsSL https://composio.dev/install | bashAfter installation, restart your terminal or source your shell config, then authenticate:
composio login # OAuth; interactive org/project picker (use -y to skip)
composio whoami # verify org_id, project_id, user_idFor agents without direct browser access: composio login --no-wait | jq to get URL/key, share URL with user, then composio login --key <cli_key> --no-wait once they complete login.
1. Use Apps via Composio CLI
Use this when: The user wants to take action on an external app directly — no code writing needed. The agent uses the CLI to search, connect, and execute tools on behalf of the user.
Key commands (new top-level aliases):
composio search "<query>"— find tools by use case
composio execute "<TOOL_SLUG>" -d '{...<input params>}'— execute a tool
composio link [toolkit]— connect a user account to an app (agents: always use--no-waitfor non-interactive mode)
composio listen— listen for real-time trigger events
Typical workflow: search → link (if needed) → execute

2. Building Apps and Agents with Composio
Use this when: Writing code — an AI agent, app, or backend service that integrates with external tools via the Composio SDK.
Run this first inside the project directory to set up the API key:
