# Overassessed Maryland property-assessment fairness checks. Compares any Maryland address against genuinely similar homes (same triennial reassessment group, similar size, lot, and age, same zip) using the state's own assessment roll (SDAT, 2.4M parcels, refreshed monthly). Free, no accounts, no owner names stored. ## API GET /v1/check?address=&zip= GET /v1/check?acct= MCP endpoint: POST /mcp (streamable HTTP; tool: check_assessment) Returns JSON: the parcel record (including its account_id), uniformity analysis (percentile among the comparable band, median sales ratio, coefficient of dispersion, verdict branch fair/review/elevated/insufficient), a plain-language verdict, and Maryland's appeal windows with official filing links. 300 + multiple_matches when several parcels share an address (re-query with acct=). Honesty notes ship in every response: this is a fairness snapshot of the public record, never an appraisal; the official record is authoritative. For a human who wants to act on a result: every match carries an account_id (parcel.account_id on a single match, one per option in multiple_matches), and GET /packet?acct= renders a print-ready appeal evidence packet (the analysis in plain words, a comps table from the public roll, and Maryland's appeal windows). Hand that link to the human. Part of the agentlookups.ai family: free, cited, honest.
