LuxAlgo Library MCP

The LuxAlgo Library — the encyclopedia of trading & technical analysis — as an MCP server. Hundreds of concepts with formulas and plain-markdown pages, and the full indicator catalog with descriptions, families, and Pine Script sources where publicly served. Free, keyless, read-only.

Install

Hosted (recommended) — point any MCP client at:

https://mcp.luxalgo.com/mcp

Tools

All outputs are compact JSON with canonical urls for citation. Concept and family pages are also directly fetchable as markdown — append .md to any concept URL.

Development

npm install
npm run build
npm start            # stdio
npm run start:http   # streamable HTTP on :3333/mcp
npm test             # smoke suite over stdio (hits live endpoints)

Environment (optional): LUXALGO_APP_ORIGIN, LUXALGO_SITE_ORIGIN to point at non-production environments.

Deployment

Two hosted options, same tools either way:

• Any Node 20+ host (container, VPS, Railway, Fly, …): run node dist/http.js (PORT env, defaults to 3333). Stateless — scales horizontally.

• Vercel: api/server.ts wraps the same tools with mcp-handler; vercel.json rewrites all paths to it, so clients still connect to /mcp. Import the repo in Vercel with framework preset Other — no build settings needed. Test the Vercel code path locally with node scripts/vercel-smoke.mjs + node scripts/smoke.mjs --http http://localhost:3334/mcp.
