Feature Request

Description

Add a Model Context Protocol (MCP) server to Mailpit that enables AI assistants like Claude, Cursor, and VS Code with Copilot to interact with the email testing environment programmatically.

Use Cases

Automated Email Analysis - AI can fetch and analyze emails for issues, spam triggers, and compatibility problems
Search & Navigation - Natural language queries to find emails (e.g., "find all emails from john last week")
Quality Checks - Automated HTML compatibility, link validation, and spam scoring
Test Automation - AI-driven email testing workflows and debugging
Template Development - AI assistance in composing and validating email templates

Proposed Features

MCP tools for all Mailpit API endpoints
Pre-built prompts for common email workflows
Resources for quick inbox state access
Support for both STDIO and HTTP transports
Docker image for easy deployment

Benefits

Enhances Mailpit's value for AI-augmented development workflows
Enables natural language interaction with email testing
Integrates with popular AI-powered IDEs and assistants

Technical Approach

Standalone Go binary using the official MCP SDK
Nested in mcp/ directory within the main repository
Separate Docker image for flexible deployment

Thank you. Whilst I appreciate the effort both you and Claude went through to vibe code this, I won't accept this into Mailpit. My reasons are simple: I do not want to support and maintain an entirely separate project (with a somewhat duplicated code-base) which I have no use for.

Please feel free to publish and maintain this "mailpit-mcp" project as your own project however, as I'm sure you and others may find it a useful bridge with AI in your testing.

Thanks for your prompt response. I have created my own project "mailpit-mcp" that we use in our dev team now, available here: https://github.com/amirhmoradi/mailpit-mcp
