# AgentMail MCP Server

Connect AgentMail to any MCP-compatible AI client. Three setup options available.

## Prerequisites

Get your API key from [console.agentmail.to](https://console.agentmail.to).

---

## Option 1: Remote MCP (Simplest)

No installation required. Connect directly to the hosted MCP server.

**URL:** `https://mcp.agentmail.to`

Add to your MCP client configuration:

```json
{
  "mcpServers": {
    "AgentMail": {
      "url": "https://mcp.agentmail.to",
      "env": {
        "AGENTMAIL_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}
```

---

## Option 2: Local npm Package

Run the MCP server locally via npx.

```json
{
  "mcpServers": {
    "AgentMail": {
      "command": "npx",
      "args": ["-y", "agentmail-mcp"],
      "env": {
        "AGENTMAIL_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}
```

### Tool Selection

Load only specific tools with the `--tools` argument:

```json
{
  "mcpServers": {
    "AgentMail": {
      "command": "npx",
      "args": [
        "-y",
        "agentmail-mcp",
        "--tools",
        "send_message,reply_to_message,list_inboxes"
      ],
      "env": {
        "AGENTMAIL_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}
```

---

## Option 3: Local Python Package

Install and run the Python MCP server.

```bash
pip install agentmail-mcp
```

### Claude Desktop

- macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`

{
  "mcpServers": {

      "env": {
        "AGENTMAIL_API_KEY": "YOUR_API_KEY"
      }

```

### "Invalid API key"

Verify your API key is correct and has the necessary permissions.

### Python package not found

Use the full path to the agentmail-mcp executable in your virtual environment:

```bash
# Find the path
source /path/to/venv/bin/activate
which agentmail-mcp
```
