Cook County (Chicago) Property Records MCP Server
A live remote MCP server at https://api.ingest0r.com/mcp (streamable-http, JSON-RPC 2.0 over HTTP POST, protocol 2025-11-25, serverInfo cook-county-chicago-property-data 1.27.2) exposing five read-only tools: get_free_sample ($0, fixed example of every response shape), search_chicago_property_by_address (always free), get_cook_county_parcel ($0.01), get_cook_county_property_dossier ($0.03) and find_chicago_comparable_sales ($0.10), each annotated readOnlyHint/idempotentHint true. tools/list answers anonymously — no OAuth, no API key — and the first 25 paid-tool calls per client per day are free; past that the tool result carries the x402 402 under _meta["x402/error"] and accepts payment via _meta["x402/payment"] (agents-SDK x402 convention). The server is also advertised at /.well-known/mcp.json. Each tool binds one-to-one to an OpenAPI operationId (see the tool crosswalk).
