A registry of standalone Python MCP servers generated from upstream OpenAPI specs for many third-party APIs. Each server exposes the API's endpoints as MCP tools and can be installed or run independently.
From the registry: Send emails and manage sending domains, suppression lists, and delivery analytics

This server lives in a monorepo. The README covers the whole collection, so we can't extract a single canonical install. The provided README is for the MCP Armory registry, which is a collection of many standalone MCP servers. It mentions Mailtrap in the server list, but does not include Mailtrap-specific installation or authentication details. It directs readers to each server's own README for full credential setup and configuration instructions.
