概要

What is mcp-email-server?

An MCP server that provides IMAP and SMTP capabilities, enabling AI agents to read, send, and manage emails over the Model Context Protocol. Designed for developers integrating email workflows into MCP clients like Claude Desktop.

How to use mcp-email-server?

Install via uvx mcp-email-server@latest stdio or pip install mcp-email-server. Configure using the interactive UI command mcp-email-server ui (writes a TOML file) or by setting environment variables (e.g., MCP_EMAIL_SERVER_EMAIL_ADDRESS, MCP_EMAIL_SERVER_PASSWORD, MCP_EMAIL_SERVER_IMAP_HOST). The server can run in read-only mode if SMTP host is omitted.

よくある質問

How do I configure mcp-email-server?

Use the interactive UI (`mcp-email-server ui`) or set environment variables prefixed with `MCP_EMAIL_SERVER_`. Environment variables take precedence over the TOML configuration file.

Can I run it in read‑only mode?

Yes. Omit the `MCP_EMAIL_SERVER_SMTP_HOST` variable or SMTP block in the config to enable read‑only mode. Outbound compose tools are hidden when every configured account is read‑only.

How do I enable attachment downloads?

By default attachment download is disabled. Set `MCP_EMAIL_SERVER_ENABLE_ATTACHMENT_DOWNLOAD=true` as an environment variable or `enable_attachment_download = true` in the TOML file.

How do I restrict who can send or receive email?

Use `MCP_EMAIL_SERVER_ALLOWED_RECIPIENTS` to limit send destinations and `MCP_EMAIL_SERVER_ALLOWED_SENDERS` (supports glob patterns) to filter inbound mail. Empty allowlists permit all.

What transport modes are supported?

The server supports `stdio` for standard MCP clients and `streamable-http` (HTTP) for web‑based integrations. HTTP mode validates Host and Origin headers to prevent DNS rebinding attacks.
