DG Floors — MCP Server

Model Context Protocol server for flooring cost data and home-improvement guides.

A public MCP (Model Context Protocol) server that lets any AI assistant query DG Floors' flooring data — installed cost per square foot by material and US state, and a search of DG Floors' flooring guides. Built on Cloudflare Workers. Public, read-only. Results carry attribution + a free-quotes CTA and (for cost) an Amazon affiliate link.

• Endpoint: https://dgfloors.com/mcp

• Transport: Streamable HTTP (JSON-RPC 2.0) · Auth: none

Tools

Both tools are read-only (readOnlyHint: true, destructiveHint: false, idempotentHint: true); the server never writes data or needs credentials.

Run with Docker

docker build -t dgfloors-mcp .
docker run -p 8787:8787 dgfloors-mcp     # MCP endpoint at http://localhost:8787/mcp

Develop / deploy

npm install
npm test         # node:test smoke tests for the JSON-RPC handler (no network)
npm run dev      # wrangler dev — local test at http://localhost:8787/mcp
npm run deploy   # wrangler deploy — serves at dgfloors.com/mcp (+ legacy alias mcp.dgfloors.com)

The cost data is bundled from the Flooring Cost Index (src/cost-index.json). To refresh: regenerate the index (flooring_cost_index.py in the content-ops repo), copy flooring_cost_data/index.json → src/cost-index.json, and redeploy.

Optional usage log: a D1 table (schema.sql) records tool calls and client handshakes (no personal data). Stats are served at /stats behind a STATS_TOKEN secret.
