docs-to-mcp

A Cloudflare Worker that turns any AI Search (AutoRAG) instance into an MCP server.

Setup

1. Create an AI Search instance in the Cloudflare dashboard

   • Create a R2 bucket and upload all your docs files - markdown, pdfs, text files etc.

   • Go to Computer & AI > AI Search(AutorRAG)

   • Create a new AI Search instance and select the R2 bucket as source (the one you previously created), just select the defaults.

2. Configure the Worker

   Update wrangler.jsonc with your AI Search name:

   "vars": {
     "AI_SEARCH_NAME": "your-ai-search-name"
   }

3. Install dependencies

   pnpm install

4. Deploy

   pnpm run deploy

Usage

MCP Endpoints

How did I test this.

I trained it on a fictional TypeScript framework with APIs named after my cat, Ustaad, so I would know it's not hallucinating, you can find these files in fake-knowledge.md
