API-first county assessor record lookup, MLS discrepancy checks, and a local MCP server for appraisers.

About assessor-lookup-public

Automated county assessor public-records search for real-estate appraisers.

Look up a property's public record — owner of record, legal description, above/below-grade square footage, beds/baths, year built, taxes, assessed and market value, lat/lon, and a link to the assessor card — straight from the county assessor. Then diff those records against your MLS data to flag discrepancies before the report goes out.

Built from an appraiser's workflow, for appraisers: the check command takes your MLS export (subject + comps) and prints a field-by-field discrepancy report (GLA, beds, baths, year built, basement sqft) in seconds instead of a county-website tab per property.

- One record model, many counties — Spatialest, Tyler EagleWeb, Aumentum, and ArcGIS platforms all normalize to the same dict. - MLS discrepancy check — reads standard MLS CSV exports (PPMLS and RESO/REColorado column names both understood) and flags GLA/beds/baths/year/ basement differences. - Auto-discovery — point it at a county it doesn't know and it maps the county for you, API-first, then caches the result. - No API keys — these are the same public endpoints the county's own property-search website uses. - Agent-ready — ships an MCP server so an AI agent can drive the whole thing. - Regression + benchmark harness — pins golden records per county and catches the day a county website changes. Packaged live fixtures use only government or institutional properties; user-onboarded records stay in the user's local config directory and are never added to the package.
