Common Standards MCP

A small, read-only Model Context Protocol (MCP) server that lets an AI assistant look up U.S. K–12 academic standards on demand, using the free Common Standards Project API. Built with TypeScript, Next.js, and Vercel's mcp-handler.

What it does

Four read-only tools:

Related MCP server: w3c-mcp

Run locally

npm install
cp .env.local.example .env.local   # optional: add a CSP_API_KEY
npm run dev                        # serves the MCP at http://localhost:3000/api/mcp
npm run test:run                   # run the test suite

Inspect it with npx @modelcontextprotocol/inspector → Streamable HTTP → http://localhost:3000/api/mcp.

Demo

Ask an assistant connected to this server:

“Look up Arizona’s 4th-grade math standards, and list a few with their codes.”

Claude calls the tools (list_jurisdictions → list_standard_sets → get_standard_set) and answers with the real standards — each carrying its CC-BY attribution:

Under the hood, list_jurisdictions filtered to “Arizona” returns:

{
  "count": 2,
  "jurisdictions": [
    { "id": "0B41FFF6B5114EB0B8A89CE0E70E22D8", "title": "Arizona", "type": "state" },
    { "id": "07130F1D86804B4D9D41E610BA605DA2", "title": "Arizona - Tucson Unified School District - Mansfeld Magnet Middle School", "type": "organization" }
  ]
}

Deploy

Deployed on Vercel. The live MCP endpoint is https://common-standards-project.vercel.app/api/mcp.

Add it to Claude Code:

• Code: MIT (see LICENSE).

• Standards data: licensed per standard set (commonly CC BY 3.0 US); each get_standard_set / get_standard result includes an attribution string. Data retrieved via the Common Standards Project.

Notes

Optional hardening for a public deployment: add a Vercel Firewall rate-limit rule, or a shared-secret header check in app/api/mcp/route.ts. Not required for read-only public data.
