MailMCP MCP Server

MCP server for intelligent calendar and task management. The mailmcp mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 3 defined tools rather than through you.

What it actually does

A powerful Model Context Protocol (MCP) server that provides intelligent calendar and task management capabilities. This server allows AI assistants to interact with your calendar through natural language, handling everything from simple event creation to complex scheduling analysis.

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Its toolset

Everything the assistant can do here goes through one of these:

• Prerequisites — The Prerequisites tool exposed by this server
• Authentication — The Authentication tool exposed by this server
• Logging — Structured JSON logging with configurable levels: - Error tracking and alerting - Performance metrics - Security event logging - Debug information

Configuration

You will need 4 environment variables: DATABASE_URL, GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, REDIS_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

• Node.js 18+ - PostgreSQL 12+ - Redis 6+ (optional but recommended) - Google Cloud Project with Calendar API enabled

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the mailmcp mcp server does with a few real requests.

When to reach for it

Among the planning and project tracking options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MailMCP's toolset — Prerequisites, Authentication, Logging — is a fair guide to whether it matches your workflow. It is maintained by momer17; worth a glance at recent repository activity before you build anything load-bearing on it.
