MCP Knowledge Server

# MCP Knowledge Server

A production-ready Remote Model Context Protocol (MCP) Server built with Cloudflare Workers that provides AI assistants with fast, structured, read-only access to Markdown knowledge stored in GitHub.

Instead of searching raw Markdown files on every request, the server indexes document metadata into Cloudflare KV, enabling low-latency retrieval while keeping hosting costs minimal.

Why Metadata Indexing?

Searching raw Markdown for every request quickly becomes expensive.

Instead:

Metadata Index
       │
