VerifyUK Property Constraints

Evidence-backed English property screening designed for repeat AI-agent use and high-volume batch due diligence.

Add cited English planning-constraint screening to every property your agent analyses.

Important: not_found_in_source is not confirmed absence. Postcode matching is approximate, source coverage varies, and this is screening rather than legal advice.

Temporary browser-AI evaluation

https://verifyuk-property-check-production.up.railway.app/mcp-demo is currently enabled and exists only for temporary evaluation. It is not the Registry endpoint and never bypasses authenticated access.

The demo requires no API key, exposes only check_property_constraints, accepts only an address containing a postcode, and is heavily rate-limited to at most 5 successful calls per IP and 100 successful calls globally each UTC day. Every response is marked demo_access.

Compact REST example

  -H 'Idempotency-Key: listing-1001-screen-v1' \
