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 Zoho mail 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 1,000+ 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 Zoho mail 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 Zoho mail

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

bash

composio search "what can I do with Zoho mail?"
composio link zoho_mail

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

4. Done!

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

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

The Zoho mail MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Zoho mail account. It provides structured and secure access to your mailbox, so your agent can perform actions like searching emails, sending messages, managing folders, organizing conversations, and handling attachments on your behalf.

Smart email search and filtering: Ask your agent to find emails based on sender, subject, keywords, or date ranges for quick information retrieval.
Automated composing and sending: Let your agent draft and send new emails, reply to existing threads, or create message templates to streamline communication.
Folder and label organization: Have your agent organize your inbox by moving messages to folders, applying tags, or archiving threads for a clutter-free workspace.
Attachment management: Retrieve, download, or send attachments through your agent—making file sharing and access seamless within your email workflow.
Bulk message actions: Instruct your agent to mark emails as read or unread, star important messages, or clean up your inbox by deleting or archiving in bulk.

Way Forward

With Zoho mail 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 Zoho mail 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 Zoho mail tools into Pi's tool list directly.

FAQ

Frequently asked questions

With a standalone Zoho mail MCP server, the agents and LLMs can only access a fixed set of Zoho mail tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Zoho mail 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 Zoho mail tools.

Yes, absolutely. You can configure which Zoho mail 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 Zoho mail data and credentials are handled as safely as possible.
