MCP server for Massachusetts public law — the Massachusetts General Laws (MGL) and the Commonwealth's rules of court. Semantic search over statute and rule text plus exact citation lookup, returning ready-to-cite source links. Public law only (no case law). Backed by a hosted Chroma Cloud vector database.

This server exposes three read-only search and citation tools for Massachusetts statutes and court rules. It reads a query, embeds it via Cloudflare Workers AI (api.cloudflare.com), and searches a Chroma Cloud vector database (api.trychroma.com) using credentials from environment variables or a local .env file. Both destinations match the declared egress allowlist, and the API key and tenant values are only used to authenticate to their respective intended services, never sent elsewhere. Tool descriptions accurately reflect their behavior with no hidden instructions or injection payloads, and no undeclared network destinations or credential leakage were found.

Tool surface

`ma_search_statutes`	Search the Massachusetts General Laws (MGL) by topic or citation.
`ma_get_statute`	Fetch the full text of one MGL section by its citation.
`ma_search_court_rules`	Search Massachusetts rules of court (Probate & Family, civil, criminal, etc.).

Egress allowlist: api.trychroma.com, api.cloudflare.com

Add to your MCP client

This is a remote MCP server over HTTP. Point any client that supports remote servers at the endpoint below and send your MCP Commons key as a bearer token.

Endpoint	`https://run.mcpcommons.com/ma-law/mcp`
Auth header	`Authorization: Bearer <your-api-key>`

claude mcp add --transport http ma-law https://run.mcpcommons.com/ma-law/mcp --header "Authorization: Bearer <your-api-key>"

Run this in your terminal. Claude Code speaks remote HTTP MCP directly.

{
  "mcpServers": {
    "ma-law": {
      "url": "https://run.mcpcommons.com/ma-law/mcp",
      "headers": {
        "Authorization": "Bearer <your-api-key>"
      }
    }
  }
}

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json in a project, then reload Cursor.

{
  "servers": {
    "ma-law": {
      "type": "http",
      "url": "https://run.mcpcommons.com/ma-law/mcp",
      "headers": {
        "Authorization": "Bearer <your-api-key>"
      }
    }
  }
}

Add to .vscode/mcp.json in your workspace. VS Code uses the servers key with type: "http".

{
  "mcpServers": {
    "ma-law": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://run.mcpcommons.com/ma-law/mcp",
        "--header",
        "Authorization:${AUTH_HEADER}"
      ],
      "env": {
        "AUTH_HEADER": "Bearer <your-api-key>"
      }
    }
  }
}

Claude Desktop's config only supports local (stdio) servers, so this bridges to the hosted endpoint with mcp-remote. Needs Node.js installed. Restart Claude Desktop after saving. It works the same whether the server is written in TypeScript or Python.

Create a key in your dashboard, claim or subscribe to this listing, then paste your key in place of <your-api-key>.
