Confirm the connection

  • The server name is dc-property-records and the production version is 0.4.10.
  • The tool catalog contains exactly 15 read-only tools.
  • There is no Recorder of Deeds tool in the catalog. Deed and sale context comes from assessor records, and citations route you to the Recorder’s official portal for verification.

Run your first property query

Enable Quoin from the Connectors menu in the chat, then paste the prompt below. Claude will ask Quoin to resolve the building before it retrieves facts.

Resolve 1717 K Street NW, Washington, DC, then give me the current owner, the current and proposed assessments, and this year's tax status, with a source link for each fact.
