AI security review

Audited · 2026.07model: claude-sonnet-5

This server exposes three read-only search tools over U.S. federal statutes and court rules. It embeds user queries via Cloudflare Workers AI and queries a vendor-hosted Chroma Cloud database, matching the declared egress allowlist (api.cloudflare.com and api.trychroma.com via the chromadb client). Credentials (Chroma API key, tenant, Cloudflare account id and token) are read from environment variables or a local .env file only to authenticate these two declared calls, never logged or sent elsewhere. Tool descriptions accurately reflect functionality with no hidden capabilities or injection payloads found.

Tool surface

`fed_search_statutes`	Search the U.S. Code by topic or citation.
`fed_get_statute`	Fetch the full text of one U.S. Code section by its citation.
`fed_search_court_rules`	Search the Federal Rules of Procedure (Civil, Criminal, Evidence, Appellate).

Declared network destinations: api.trychroma.com, api.cloudflare.com. Checked against the source during review.

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/federal-law/mcp`
Auth header	`Authorization: Bearer <your-api-key>`

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

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

{
  "mcpServers": {
    "federal-law": {
      "url": "https://run.mcpcommons.com/federal-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": {
    "federal-law": {
      "type": "http",
      "url": "https://run.mcpcommons.com/federal-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": {
    "federal-law": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://run.mcpcommons.com/federal-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>.
