## Description
Cook County / Chicago property records — parcels, recorded sales, building permits, tax assessments, and comparable sales by street address or PIN. Hosted remote MCP, pay-per-call via x402 (USDC on Base/Solana).

## Tools
Capabilities this server exposes over MCP:

- **get_free_sample** — Fixed example of every response shape — evaluate before paying.
- **search_chicago_property_by_address** — Resolve a street address → parcel PIN(s). The no-PIN entry point.
- **get_cook_county_parcel** — Single parcel record by 14-digit PIN.
- **get_cook_county_property_dossier** — Full dossier: address, sales & deed history, permits, assessment history.
- **find_chicago_comparable_sales** — Comparable sales + implied low/median/high valuation.

## Documentation

## What hyperionxmota/cook-county-property-mcp MCP server does

The hyperionxmota/cook-county-property-mcp MCP server exposes Cook County, Illinois property data, including records for the City of Chicago. Its responses combine parcel information with recorded sales and deed history, building permits, and property-tax assessment history. It also provides comparable-sale results with an implied low, median, and high valuation range.

The data is property-keyed public information. It does not include owner or occupant personal data. Coverage is approximately 1.9 million parcels, with source data refreshed nightly from the Cook County Assessor, Cook County Recorder of Deeds, and Chicago open-data portals.

## How it works

Use `search_chicago_property_by_address` when the input is a street address and no PIN is available. The result resolves the address to one or more parcel PINs. PIN-based tools can then retrieve a single parcel or a broader property dossier.

The dossier combines address details, transactions and deeds, permits, and assessment history into one response. Permit records are linked to parcels through derived matching because the Chicago permits feed does not provide a PIN. The service uses exact address matching and nearest-parcel geographic matching for that linkage. Parcel addresses are also joined from a separate dataset because the parcel source does not contain an address.

Comparable sales are filtered and matched by factors such as arm's-length status, neighborhood, and property class. This produces derived valuation ranges rather than simply returning an individual source row.

## Setup and configuration

The hyperionxmota/cook-county-property-mcp MCP server is hosted at `https://api.ingest0r.com/mcp` and uses streamable HTTP. Add that endpoint to an MCP client; there is no local package installation described in the provided material.

No signup or API key is required. Paid requests use the x402 protocol and are settled in USDC on either Base or Solana. The free sample is also available at `https://api.ingest0r.com/v1/sample`, and the service publishes an OpenAPI description and machine-readable pricing information through its API site.

## Tools and capabilities

- `get_free_sample` returns a fixed example covering the response shapes without payment.
- `search_chicago_property_by_address` resolves a Chicago street address to parcel PINs and is free to use.
- `get_cook_county_parcel` returns one parcel record for a 14-digit PIN. The listed price is $0.01 per call.
- `get_cook_county_property_dossier` returns the joined address, sales and deed history, permits, and assessment history. The listed price is $0.03 per call.
- `find_chicago_comparable_sales` returns comparable transactions and an implied low, median, and high valuation. The listed price is $0.10 per call.

The PIN-based routes can respond with HTTP 402 payment terms. Three listed real parcels are available free on paid routes for verification against county portals.

## Limitations and notes

Results are limited to Cook County and Chicago property records covered by the stated public-data sources. The service does not provide raw owner or occupant personal data. Comparable valuations are automated derived estimates, and permit-to-parcel relationships rely on address and geographic matching rather than a source PIN.

Free access is limited to the sample, address search, and specifically listed free parcel examples. Other parcel, dossier, and comparable-sales calls require x402 payment.
