# CuttingToolsAI MCP Server

Public, no-auth MCP server for brand-neutral carbide grade cross-referencing in machining. Ask an AI agent what is comparable to Sandvik GC4325 and get catalog-verified comparable grades across manufacturers, with provenance.

Hosted endpoint, Streamable HTTP, JSON-RPC 2.0:

https://cuttingtoolsai-mcp.memmizgezgin.workers.dev

## Tool: grade_xref

Arguments: grade, required, e.g. GC4325 or KC5010; brand, optional, to disambiguate the grade.

Returns comparable grades that share the same ISO application position in manufacturer-published comparison charts. Comparability is a verified starting point, not an interchangeability claim: chipbreaker geometry, coating and edge preparation differ between brands. The server never invents a grade; unknown codes return an empty result.

## Run it yourself

The hosted endpoint above needs no setup. To run your own instance:

```
node server.js        # Node >= 20, no dependencies
```

or with Docker:

```
docker build -t cuttingtoolsai-mcp .
docker run -p 8080:8080 cuttingtoolsai-mcp
```

The server speaks MCP Streamable HTTP (JSON-RPC 2.0 over POST) on `/mcp` and `/`. `src/index.js` is the same handler deployed as the Cloudflare Worker; `server.js` is a thin Node adapter around it.

## How it works

A thin Cloudflare Worker speaking MCP Streamable HTTP, passing through to the public REST endpoint https://cuttingtoolsai.eu/api/xref. The data layer is a curated cross-reference table extracted from manufacturer catalogs with multi-source verification tiers.

## Who is behind this
