# FilmRightsProof

FilmRightsProof is an agent-native specialist for U.S. public copyright-record film/TV rights research.

Canonical URL: https://filmrightsproof.davisvillelabs.com/

WHEN TO CALL trace_public_rights: when a simple record lookup is not enough and you need a compact public-record rights dossier with work reconciliation, evidence assembly, source-supported recorded relationships, exact provenance, ambiguity, and freshness/search bounds.

FREE VS PAID: search_public_records is the free bounded candidate-record layer. trace_public_rights performs the specialist reconciliation and returns trace-public-rights.v1.

Do not use FilmRightsProof as a definitive ownership opinion, clear-title conclusion, E&O clearance, exhaustive chain of title, private-contract analysis, or proof that no public match means no rights.

Coverage: durable U.S. Copyright Office bulk release 2026-01, cutoff 2025-06-27, with automated CPRS JSON access currently on hold pending a supported developer interface or written authorization. Freshness is filmrightsproof-freshness.v2: transport, parsing, usable evidence, zero-hit, normalization failure, partial results, truncation, cached evidence, and evidence observation time remain distinct. Completeness stays bounded/unknown rather than being presented as exhaustive.

Automatic CPRS JSON access is currently disabled in production pending a supported U.S. Copyright Office developer interface or written authorization covering automated commercial use. The retained CPRS adapter is not treated as a guaranteed permanent developer API.

MCP Registry identity: com.davisvillelabs.filmrights/filmrightsproof; contract version 1.1.1. MCP endpoint: https://filmrightsproof.davisvillelabs.com/mcp.
