It runs on Grok 4.5, plans its work before it acts, and can run multiple sub-agents in parallel. It also reads Claude Code's MCP configuration, so any server you already have in a .mcp.json is picked up with no changes. In this guide, I will show you how to connect your Agent mail account to Grok Build through Composio, so it can show me unread emails from today, send a status update to your team, find emails with invoice attachments, and more without leaving the terminal. Composio holds the OAuth tokens for you, and Grok Build only calls the tools you approve. ## Also integrate Agent mail with - [ChatGPT Work](https://composio.dev/toolkits/agent_mail/framework/chatgpt) - [Antigravity](https://composio.dev/toolkits/agent_mail/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/agent_mail/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/agent_mail/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/agent_mail/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/agent_mail/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/agent_mail/framework/codex) - [Cursor](https://composio.dev/toolkits/agent_mail/framework/cursor) - [VS Code](https://composio.dev/toolkits/agent_mail/framework/vscode) - [OpenCode](https://composio.dev/toolkits/agent_mail/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/agent_mail/framework/openclaw) - [Hermes](https://composio.dev/toolkits/agent_mail/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/agent_mail/framework/google-adk) - [LangChain](https://composio.dev/toolkits/agent_mail/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/agent_mail/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/agent_mail/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/agent_mail/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/agent_mail/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/agent_mail/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/agent_mail/framework/autogen) ## TL;DR ### Why use Composio over a standalone MCP server? - Read and write access. Composio's Agent mail integration lets Grok Build take real actions like creating drafts, sending updates, and labeling records, not just reading data. - 1,000+ SaaS toolkits out of the box. One endpoint gives you a full catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce. - One MCP server for every app. Wire up a single Composio server instead of maintaining a separate MCP entry for each app. - Smart, context-aware tool loading. Grok Build caps how many tools it holds in a single request. Composio loads only the tools a task needs, so you do not spend that budget on tools you are not using. - Cross-app automation. Chain actions across apps in one run. Pull a thread, summarize it in Notion, and post the highlights to Slack from a single prompt. ## Connect Agent mail to Grok Build ### Prerequisites - Grok Build installed and signed in. Install with curl -fsSL https://x.ai/cli/install.sh | bash on macOS or Linux, or irm https://x.ai/cli/install.ps1 | iex on Windows PowerShell. On first launch Grok opens a browser to authenticate; for headless or CI use, set an XAI_API_KEY environment variable instead (create the key at [console.x.ai](https://console.x.ai/)). - Access to the Agent mail account you want to connect. - The [Composio MCP endpoint](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=grok-build&utm_content=composio_connect). Composio's server is remote and hosted, so there is nothing to run locally and no tunnel to set up. ### Step-by-step: Connect Agent mail to Grok Build ### 1. Install and verify Grok Build Install the CLI, then restart your shell so the grok binary lands on your PATH: ```bash curl -fsSL https://x.ai/cli/install.sh | bash which grok ``` ## What is the Agent mail MCP server, and what's possible with it? The Agent 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 Agent mail account. It provides structured and secure access to your agent's dedicated inbox, so your agent can send emails, receive incoming messages, fetch specific conversations, and automate email-based workflows on your behalf. - Automated email sending: Instruct your agent to compose and send emails to any recipient, perfect for status updates, notifications, or outreach. - Message listing and inbox scanning: Let your agent quickly list all recent messages in the inbox to summarize, monitor, or trigger follow-up actions. - Targeted message retrieval: Have your agent fetch a specific message by ID, making it easy to pull full email content for context-aware decisions or replies. - Streamlined agent-to-agent communication: Enable your AI to directly interact with other agents or services via email, automating routine communication flows. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `AGENT_MAIL_CREATE_INBOX` | Create Inbox | Create a new AgentMail inbox via API. Returns the inbox_id and email address for sending/receiving messages.

A standalone Agent mail MCP server gives Grok Build a fixed set of Agent mail tools tied to that one server. The Composio Tool Router lets Grok Build load tools from Agent mail and many other apps on demand, based on the task, all through a single endpoint. ### Does Grok Build support MCP? Yes. Grok Build ships with native MCP support. Add a server with the grok mcp add command, from the in-session /mcps modal, or by editing ~/.grok/config.toml. It also reads Claude Code-style .mcp.json files, so Grok Build discovers the tools automatically. ### Can I reuse the same MCP config I already use with Claude Code? Yes. Grok Build has zero-migration compatibility with Claude Code's configuration, so the same Composio server entry works in both without edits. ### How safe is my Agent mail data with Composio? Tokens, keys, and configuration are encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant, so your Agent mail data and credentials are handled to that standard. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
