Provides AI assistants with Model Context Protocol (MCP) access to Fastmail accounts for email management.
Installation

Security Notes
The server correctly extracts the Fastmail API token from the Authorization header. It hashes this token before using it as a Redis key, avoiding storage of raw tokens in Redis keys. However, the full session JSON, which can contain sensitive account IDs, is cached in Redis. While given a TTL, a compromise of the Redis instance could expose this data. Input validation for tools is enforced using Zod schemas. The server explicitly warns users to keep their API tokens secure and not commit them to version control. The open CORS configuration (origin: '*') is typical for MCP but means no origin-based protection beyond the bearer token.
