Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

chicago
find_chicago_comparable_sales
Recent arm's-length comparable sales (comps) in the same Cook County assessor neighborhood and property class as the given PIN, with an implied low/median/high price range — a derived, lightweight automated valuation you won't get from a raw open-data query. Costs $0.10 per call (x402, USDC) — the highest-value route; try get_free_sample first.
search_chicago_property_by_address
Resolve a Cook County / Chicago street address (full or partial) to its parcel PIN(s) — ranked candidates with address, city, ZIP, and match score. Call this FIRST when you have an address but not a PIN, then pass a returned pin to get_cook_county_parcel / get_cook_county_property_dossier / find_chicago_comparable_sales. FREE — no payment required.
cook
get_cook_county_parcel
Cook County, IL parcel record (address, assessor class, township, neighborhood, ward, schools, lat/lon) for a 10- or 14-digit PIN. Costs $0.01 per call (x402, USDC).
get_cook_county_property_dossier
Full Cook County / Chicago property dossier (parcel basics, recorded sales & deed history, building permits, property-tax assessment history, location context) for a PIN — the one-call due-diligence record. Permits are LINKED to the PIN here (the raw permit open-data has no PIN; links are derived by address + geo match), so this is a finished record you can't reproduce with raw open-data queries. Costs $0.03 per call (x402, USDC).
free
get_free_sample
FREE ($0, no payment): a fixed, representative example of every paid response shape (search, parcel, dossier, comps). Call this FIRST to validate the data structure and quality before spending anything.

Cook County / Chicago Property Data — questions

Answers built from our own checks of this server.

It exposes 5 tools, read directly from the server on our last check. Among them: find_chicago_comparable_sales, get_cook_county_parcel, get_cook_county_property_dossier, get_free_sample, search_chicago_property_by_address. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is Cook County / Chicago Property Data mostly used for?
Its tools cluster around chicago and cook. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Cook County / Chicago Property Data working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 480 ms. The bar chart above shows every period we have measured.
How do I connect Cook County / Chicago Property Data?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Cook County / Chicago Property Data need an API key?
No. Cook County / Chicago Property Data completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Cook County / Chicago Property Data?
It answers our handshake in 480 ms on average, which is faster than 25% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
