## Decision facts: pi-mcp-adapter

- **Requirements:** pi-mcp-adapter operates in a TypeScript environment and requires that the project already supports TypeScript.
- **Adopt for:** pi-mcp-adapter is a TypeScript-based MCP adapter tailored for efficient token usage with Pi, an AI coding assistant.
- **License detail:** Licensed under MIT

## Decision facts: fastmcp

- **Requirements:** fastmcp can be added to your project using the uv package manager, but full installation instructions are available on the official documentation.
- **Adopt for:** fastmcp is a Python library for building MCP servers and clients, designed to facilitate the Model Context Protocol (MCP) in AI development.
- **License detail:** fastmcp is licensed under the Apache-2.0 license, allowing for broad use in both open-source and commercial projects.

## Choose when

### Choose pi-mcp-adapter if…

- pi-mcp-adapter is primarily TypeScript; fastmcp is Python.
- License: pi-mcp-adapter is MIT, fastmcp is Apache-2.0.
- Requirements: pi-mcp-adapter operates in a TypeScript environment and requires that the project already supports TypeScript..
- Tags unique to pi-mcp-adapter: ai, claude, coding-agent, extension.
- pi-mcp-adapter ships an MCP server manifest.
- Use when working with Pi, the AI coding assistant, to optimize token efficiency within Model Context Protocol environments.

### Choose fastmcp if…

- fastmcp is primarily Python; pi-mcp-adapter is TypeScript.
- License: fastmcp is Apache-2.0, pi-mcp-adapter 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, llms, mcp-clients.
- Also covers Developer Tools.
- 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 pi-mcp-adapter

- Avoid if your project does not align with TypeScript or the Model Context Protocol framework as pi-mcp-adapter is specifically tailored for these contexts.
- Do not use when working on projects that do not involve Pi coding assistant, as its functionalities are directly tied to this specific AI tool.

## 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.
