Composio x Pi Extension

Pi package that installs a Pi extension for Composio-backed runtime and authoring tools.

Install

Install the published npm package with Pi:

pi install npm:composio-x-pi

For a pinned version:

pi install npm:composio-x-pi@0.0.1

During development, install from a local checkout:

cd /path/to/composio-x-pi
bun install
pi install /path/to/composio-x-pi

Try the extension for one Pi run without adding it to settings:

pi -e /path/to/composio-x-pi/src/index.ts

After editing an installed local checkout, use /reload inside Pi.

Publishing

This package is intended to be installed through Pi's npm package source, so releases should be published to npm under the composio-x-pi package name:

bun run test
bun run typecheck
bun run build
npm publish

Configuration

This extension is explicitly API-key based. Running composio login in a shell is not used by the Pi extension; the extension only reads a Composio API key that you provide directly.

Recommended setup inside Pi:

/composio-init

The command prompts for your key and stores it in ~/.pi/agent/extensions/composio-x-pi.json with file mode 0600. You can also pass the key as an argument (/composio-init <key>), but the interactive prompt avoids leaving the key in chat history.

Environment override:

• COMPOSIO_API_KEY — if set, this takes precedence over the stored key.

Optional environment variables:

• COMPOSIO_PI_MODE=authoring|worktree — defaults to worktree; authoring enables trigger-authoring tools.
• COMPOSIO_PI_IPC_SOCK — override the local Unix socket path used by save_automation_local.
• COMPOSIO_PI_WEBHOOK_TEST_URL — endpoint used by test_webhook_delivery to fire a local test webhook.
• COMPOSIO_PI_EVENT_POLL_URL — endpoint used by test_webhook_delivery to poll for received events.

Commands

• /composio-init — securely prompt for and store the Composio API key used by this extension.

Tools

Always registered:

• composio_debug_info
• composio_search_tools
• composio_get_tool_schemas
• composio_execute_tool
• composio_manage_connections

Authoring-only:

• composio_list_trigger_types
• composio_get_trigger_type_schema
• composio_create_trigger
• composio_list_triggers
• composio_toggle_trigger
• composio_delete_trigger
• test_webhook_delivery
• save_automation_local

Local scripts

• bun test
• bun run typecheck
• bun run build
• bun run test:integration
• bun run dev:pi
• bun run dev:ipc-stub

bun run dev:pi loads the extension from src/index.ts through Pi's embedding API. bun run dev:ipc-stub starts a JSON-line Unix socket server that accepts saveAutomationLocal requests for local testing.
