About

FastMCP is an open source, Pythonic framework for building Model Context Protocol (MCP) applications that makes creating, managing, and interacting with MCP servers simple and production-ready by handling the protocol’s complexity so developers can focus on business logic. The Model Context Protocol (MCP) is a standardized way for large language models to securely connect to tools, data, and services, and FastMCP provides a clean API to implement that protocol with minimal boilerplate, using Python decorators to register tools, resources, and prompts. A typical FastMCP server is created by instantiating a FastMCP object, decorating Python functions as tools (functions the LLM can invoke), and then running the server with built-in transport options like stdio or HTTP; this lets AI clients call into your code as if it were part of the model’s context.

About

Stainless is a developer infrastructure platform that automatically generates production-ready SDKs, API documentation, and MCP (Model Context Protocol) servers directly from OpenAPI specifications. The platform helps API companies deliver high-quality developer and agent experiences by creating idiomatic SDKs for multiple programming languages including TypeScript, Python, Go, Java, Ruby, C#, and PHP. Stainless automates the maintenance of SDKs and documentation, ensuring they stay synchronized with API changes while reducing engineering overhead. The platform is designed to improve API usability, streamline integrations, and support AI agent interoperability through standards-based MCP server generation.
