Check if the CLI is installed; if not, install it:
curl -fsSL https://composio.dev/install | bash
After 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_id
For 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.
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 casecomposio execute "<TOOL_SLUG>" -d '{...<input params>}' — execute a toolcomposio link [toolkit] — connect a user account to an app (agents: always use --no-wait for non-interactive mode)composio listen — listen for real-time trigger eventsTypical workflow: search → link (if needed) → execute

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:
composio init
