selvedge vs fastapi_mcp
selvedge: Selvedge provides long-term memory for AI-coded codebases, capturing the 'why' behind agent-made changes directly from the agent's context. It acts as a local MCP server, logging structured events to a SQLite database, allowing developers to query the reasoning for code modifications years later.; fastapi_mcp: FastAPI-MCP allows you to expose your existing FastAPI endpoints as Model Context Protocol (MCP) tools. It offers native integration with FastAPI, including built-in authentication using existing dependencies, and preserves schemas and documentation.

When to choose:
- You already have a FastAPI application and want to expose its endpoints as MCP tools while reusing your existing FastAPI authentication dependencies and Swagger schemas.
- You want to mount the MCP server directly onto your ASGI app or deploy it separately under an MIT license.
When to skip:
- You are building a standalone MCP server from scratch rather than wrapping a FastAPI app; use FastMCP or the official MCP Python SDK.
- You need an actively updated repository (last push was November 2025).

Use Cases
selvedge↳Understanding the historical 'why' behind schema decisions and migrations in long-term AI-coded projects.
↳Providing an audit trail for AI-generated code changes, essential for compliance (e.g., SOC 2, EU AI Act).
↳Helping solo developers recall the purpose of AI-generated code in their side projects or internal tools.
↳Enforcing checks for prior attempts on entities to prevent agents from re-introducing reverted decisions.
↳Tracking the full scope of a feature or task across multiple entities and commits using changesets.
fastapi_mcp↳Integrating FastAPI services as tools for large language models (LLMs) that support MCP.
↳Enabling LLMs to interact with and utilize existing business logic and data exposed via FastAPI.
↳Quickly exposing authenticated FastAPI APIs as discoverable and usable tools within an MCP ecosystem.
