CTX vs fastapi_mcp

CTX: CTX is a local context runtime for OpenCode and AI coding agents. It reduces token waste by indexing repositories, storing reusable guidance as graph memory, and providing compact task packs, read-cache compression, command pruning, and a live right-sidebar dashboard. It integrates natively with OpenCode as a context layer without replacing the agent launcher.; 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).
