espaciarte-mcp

Minimal MCP server exposing Espaciarte's public space discovery to external AI clients (Claude Desktop, Cursor). A thin, read-only wrapper over the backend REST API — no database access, no LLM calls, no auth, no secrets.

Tools

The backend already handles privacy (published spaces only, obfuscated locations, no PII); this server returns its responses untouched.

Related MCP server: geocontext

Setup

pnpm install
pnpm build

Requires the backend running (default http://localhost:8000 — pnpm dev in espaciarte-backend/ with the DB up).

Configuration

Single env var:

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "espaciarte": {
      "command": "node",
      "args": ["/Users/vicentecantu/Development/espaciarte/espaciarte-mcp/dist/index.js"],
      "env": { "BACKEND_BASE_URL": "http://localhost:8000" }
    }
  }
}

Cursor (~/.cursor/mcp.json or .cursor/mcp.json)

{
  "mcpServers": {
    "espaciarte": {
      "command": "node",
      "args": ["/Users/vicentecantu/Development/espaciarte/espaciarte-mcp/dist/index.js"],
      "env": { "BACKEND_BASE_URL": "http://localhost:8000" }
    }
  }
}

Smoke test

pnpm smoke     # 9-check battery: both tools live, error paths, privacy fields (needs backend up)
pnpm inspect   # MCP Inspector UI against the built server

Or headless: npx @modelcontextprotocol/inspector --cli node dist/index.js --method tools/list

Note: local seed data is geo-centered on Monterrey (25.6866, -100.3161) — searches around other cities correctly return 0 items.
