Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Umarelli maps construction in New York City and Jersey City from public records. Use search to find a building by address, fetch for its permits, taxes, tax breaks and zoning, and recent_permits for new buildings and major renovations near an address. Figures come from city open data, refreshed within a day of each release, and some city datasets only update quarterly or yearly; link people to the Umarelli page for each building.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http umarelli-mcp https://umarelli.org/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add umarelli-mcp --url https://umarelli.org/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable umarelli-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "umarelli-mcp": {
      "url": "https://umarelli.org/mcp"
    }
