المحتويات
Cook County / Chicago Property Data — MCP server
A hosted, pay-per-call Model Context Protocol (MCP) server for Cook County, Illinois — including the City of Chicago — property records: parcels, recorded sales & deed history, building permits, and property-tax assessment history, joined and normalized into one answer. Plus comparable sales (comps) and a lightweight automated valuation.
No signup, no API key — pay per call via the x402 protocol (USDC on Base or Solana).
What this adds over raw open data
This returns finished, joined answers — not raw rows you have to query and stitch. The county open data (Socrata) can't give you:
- Building permits linked to a PIN. The Chicago permits feed has no PIN field — the permit→parcel link is derived here (exact address match + nearest-parcel geo match). You can't reproduce this with a raw SoQL query.
- A street address on a parcel. Parcel Universe has no address; it's joined in from a separate dataset here.
- Comparable-sales valuation. Arm's-length filtering, same-neighborhood/class matching, and an implied low/median/high range — derived analysis, not a row fetch.
So one call returns a normalized property record; against raw open data you'd orchestrate multiple datasets and rebuild joins that don't exist upstream.
