Introduction

Pi is a minimal, self-extensible coding agent that lives in your terminal — one agent loop over Claude, GPT-5, Gemini, Grok, DeepSeek, and 20+ other providers, with maximum extension surface and minimum product opinion. Its core ships four tools (read, write, edit, bash) and self-extends at runtime through skills, extensions, and packages.

This guide explains the easiest and most robust way to connect your Whatsapp account to Pi. You can do this through either Composio Connect CLI or Composio Connect MCP. Because Pi already runs shell commands as first-class tools and ships no built-in MCP, the CLI is the recommended path — it's faster to set up, needs no server config, and chains multi-step tasks more reliably. The MCP path is also fully supported through Pi's official pi-mcp-adapter extension.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,500+ applications directly into their agent harness — including Pi. It can:

Search and load tools from relevant toolkits on-demand, reducing context usage.
Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
Manage app authentication end-to-end with zero manual overhead.

Connect Whatsapp to Pi with Composio

Prerequisites: Install Pi

Pi needs Node.js 18+ (Node 22 recommended). Install the agent globally with npm:

bash

npm install -g --ignore-scripts @earendil-works/pi-coding-agent

On Linux or macOS you can use the installer script instead:

bash

curl -fsSL https://pi.dev/install.sh | sh

Then run pi in any project directory and authenticate your model provider — use /login inside Pi for subscription providers (Claude Pro/Max, ChatGPT, GitHub Copilot), or set an API key such as ANTHROPIC_API_KEY before starting. Confirm it's working:

bash

pi --version

Full first-run details are in the Pi Quickstart.

Option 1: Composio CLI (recommended)

Pi runs shell commands as first-class tools, so the Composio Universal CLI is the most natural fit — no MCP server to configure and reliable multi-step tool chaining. Install and authenticate:

bash

# Install the Composio CLI
curl -fsSL https://composio.dev/install | bash

# Log in to Composio
composio login

Connect to Whatsapp

Ask Pi to connect to Whatsapp, or simply request any Whatsapp-related task. Under the hood Pi calls Composio commands like any other shell tool:

bash

composio search "what can I do with Whatsapp?"
composio link whatsapp

On the first Whatsapp call, composio link whatsapp opens an OAuth prompt so you can authorize access. After that, every Whatsapp command works with your stored credentials automatically — just talk to Pi and it will search, execute, and chain Whatsapp tools as needed.

Option 2: Composio MCP

Pi's core intentionally ships no built-in MCP, but the official pi-mcp-adapter extension adds full MCP support — exposing every server through a single lightweight proxy tool (~200 tokens) instead of loading hundreds of tool definitions into context.

1. Install the MCP adapter extension

bash

pi install npm:pi-mcp-adapter

Restart Pi after installation.

2. Add the Composio MCP server

Create (or edit) a .mcp.json file in your project root, or ~/.config/mcp/mcp.json for a user-global setup:

bash

{
  "mcpServers": {
    "composio": {
      "url": "https://connect.composio.dev/mcp"
    }
  }
}

The adapter connects lazily by default — the server won't start until Pi actually calls one of its tools, and cached metadata keeps search and describe working without a live connection.

3. Authenticate

Run /mcp-auth inside Pi to open the authentication modal and select composio from the list. Complete the sign-in in your browser, then on the consent screen click Allow access to authorize Composio. Once approved, the server shows as connected inside Pi:

Pi /mcp-auth modal listing the composio MCP server

Composio OAuth consent screen with the Allow access button

4. Done!

Confirm the server is live with /mcp to open the interactive panel, then ask Pi to connect to Whatsapp or request any Whatsapp-related task — it will prompt you to authorize Whatsapp on first use.

What is the Whatsapp MCP server, and what's possible with it?

The WhatsApp MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your WhatsApp account. It provides structured and secure access to your WhatsApp Business account settings, profiles, templates, flows, and phone configuration, so your agent can manage business details, register phone numbers, maintain templates, update flows, and review account settings on your behalf.

Business profile management: Have your agent update your business description, contact information, and other WhatsApp Business profile settings.
Phone number administration: Direct your agent to register or deregister a WhatsApp Business phone number and set its two-step verification PIN.
Message template management: Let the agent browse the template library and create or update templates for your WhatsApp Business account.
Flow and commerce configuration: Instruct your agent to review Flow assets, update Flow configurations, and check commerce settings for your business phone number.
Account oversight and access: Have your agent review owned or shared business accounts, inspect compliance and encryption details, manage assigned user access, and subscribe your application to account notifications.

Way Forward

With Whatsapp connected, Pi can now act on your behalf whenever you ask it to.

From here, you can extend Pi further:

Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Pi can do for you.
Build workflows across tools: Once multiple apps are connected, Pi can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
Lean into Pi's extension surface: Wrap common Whatsapp flows as Pi skills or prompt templates so recurring tasks become one-line commands, and use directTools in the MCP adapter to promote your most-used Whatsapp tools into Pi's tool list directly.

FAQ

Frequently asked questions

With a standalone Whatsapp MCP server, the agents and LLMs can only access a fixed set of Whatsapp tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Whatsapp and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Pi fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Whatsapp tools.

Yes, absolutely. You can configure which Whatsapp scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Whatsapp data and credentials are handled as safely as possible.
