Choose mcp-use if…
- mcp-use is primarily TypeScript; fastmcp is Python.
- License: mcp-use is MIT, fastmcp is Apache-2.0.
- Tags unique to mcp-use: agentic-framework, ai, apps-sdk, chatgpt.
- If your project involves building an application or server that needs to be integrated with both ChatGPT and Claude using TypeScript, then mcp-use is tailored for this scenario.
When NOT to use mcp-use
- Do not use if your project requires a different programming language, as mcp-use strictly supports TypeScript.
- Avoid using it when your application does not need integration with ChatGPT and Claude, since the framework is specifically designed for these two platforms.
Choose fastmcp if…
- fastmcp is primarily Python; mcp-use is TypeScript.
- License: fastmcp is Apache-2.0, mcp-use is MIT.
- Requirements: fastmcp can be added to your project using the uv package manager, but full installation instructions are available on the official documentation..
- Tags unique to fastmcp: agents, fastmcp, mcp, mcp-clients.
- Use fastmcp when you need to build MCP servers and clients in Python, as it provides a streamlined and Pythonic approach to implementing the Model Context Protocol.
When NOT to use fastmcp
- Avoid fastmcp if your project does not require the Model Context Protocol (MCP), as it is specialized for this protocol and may introduce unnecessary complexity.
- Do not use fastmcp if you are working in a language other than Python, as it is a Python-specific library and will not be compatible with other languages.
