Example 1: property facts and sources

Paste this prompt into Claude after the connector is enabled. It demonstrates address resolution, assessment stages, tax status, and source links in one request.

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.

Example 2: permits and enforcement

This prompt exercises the bounded regulatory tools and requires the response to preserve the difference between an empty linked result and unavailable coverage.

For 1717 K Street NW, Washington, DC, show the available permit, license, inspection, and enforcement history. Separate empty results from unavailable data, preserve property-link scope, and cite the official source for each record family.

Example 3: bounded property screening

This prompt demonstrates an allowlisted, limited search. The result supports professional research and must not be presented as an approval, eligibility, underwriting, or lending decision.

Find up to 10 commercial properties in Ward 2, sort them by assessed value from highest to lowest, and summarize the returned assessment and tax-balance fields with their limitations. Do not make a lending or eligibility decision.

Connecting another client or building an agent?

Add the HTTPS MCP endpoint to a client that supports remote MCP and OAuth. The browser authorization flow uses WorkOS AuthKit; never paste a bearer token into a public configuration file. Resolve a Washington, D.C. address or SSL before requesting facts.

• Use get_complete_property_record only when the request asks for all available sections.
• Use a domain tool for assessments, taxes, sales, permits, licenses, inspections, or building context.
• Present sources to end users and keep exact-versus-contextual link scope visible.
