# LocalProof Local government intelligence for AI agents. Canonical: https://localproof.davisvillelabs.com Docs: https://localproof.davisvillelabs.com/docs Trust: https://localproof.davisvillelabs.com/trust MCP: https://localproof.davisvillelabs.com/mcp OpenAPI: https://localproof.davisvillelabs.com/openapi.json Capabilities: https://localproof.davisvillelabs.com/v1/capabilities ## MCP tools - localproof.resolve_jurisdiction — Free. Resolve one address or place to a supported LocalProof jurisdiction and coverage state before deeper research. Use this when jurisdiction support is unknown; use get_coverage to inspect published coverage without resolving a property. Held or unsupported jurisdictions fail closed before paid work. - localproof.get_coverage — Free. Return released and held jurisdiction and operation coverage without querying property records. Use this to plan routing; use resolve_jurisdiction when you have a specific address. - localproof.get_source_catalog — Free. Return registered authoritative sources and freshness expectations for a jurisdiction. Use this to understand evidence sources; use get_source_health for current endpoint reachability. - localproof.get_source_health — Free. Probe registered official-source reachability for a jurisdiction without returning source records. Use this for current source availability; use get_source_catalog for source identity and freshness expectations. Reachability is not completeness. - localproof.check_property_changes — Paid $0.03 USD. Find timestamped changes after an ISO 8601 since value across released evidence dimensions for a resolved property, currently comprehensive in San Francisco. Use this for repeat polling; use check_permits for current permit detail or build_property_intelligence_pack for a full current snapshot. Unsupported or held jurisdictions fail before payment. - localproof.check_permits — Paid $0.09 USD. Reconcile current official permit records for one resolved property where permit coverage is released. Use this for permit detail; use check_permit_routing for San Francisco review routing and holds or build_property_intelligence_pack for cross-source context. Unsupported or held jurisdictions fail before payment. - localproof.check_permit_routing — Paid $0.25 USD. Trace released San Francisco permit review routing, departments, holds, timing, and recorded outcomes. Use this for administrative routing state; use check_permits for permit records. Unsupported or held jurisdictions fail before payment. - localproof.check_parcel_context — Paid $0.06 USD. Return privacy-minimized official parcel and land-use attributes where a supported parcel source is released. Use this for parcel facts; use check_zoning_context for released zoning context or build_property_intelligence_pack for cross-source context. Unsupported or held jurisdictions fail before payment. - localproof.check_planning_activity — Paid $0.25 USD. Reconcile released planning applications and entitlement activity for one property. Use this for planning records; use check_zoning_context for current zoning context or build_property_intelligence_pack for multi-source context. Unsupported or held jurisdictions fail before payment. - localproof.check_code_enforcement — Paid $0.25 USD. Reconcile released code-enforcement and complaint records for one property. Use this for enforcement evidence; use build_property_intelligence_pack for a broader package. Unsupported or held jurisdictions fail before payment. - localproof.check_zoning_context — Paid $0.01 USD. Return released official zoning context for a resolved property. Use this for zoning evidence, not a proposed-use or legal determination; use check_parcel_context for parcel attributes. Unsupported or held jurisdictions fail before payment. - localproof.build_property_intelligence_pack — Paid $0.25 USD. Build the broad released multi-source property package with completeness, source gaps, provenance, and repeat-poll guidance through check_property_changes. Use this for a comprehensive current property view; use focused check_* tools when only one evidence class is needed. Unsupported or held jurisdictions fail before payment. - localproof.compare_sites — Paid $0.49 USD. Compare two or three distinct candidate San Francisco sites across the same released evidence dimensions without selecting a winner. Use this for side-by-side site evidence; use build_property_intelligence_pack for one site. Unsupported or held jurisdictions fail before payment. - localproof.build_development_due_diligence — Paid $2.95 USD. Build the deepest released San Francisco development evidence package with cross-source chronology, attention items, completeness, source gaps, provenance, and repeat-poll guidance through check_property_changes. Use this for development due diligence; use build_property_intelligence_pack for a lighter current snapshot. Unsupported or held jurisdictions fail before payment. ## HTTP operations - localproof.resolve_jurisdiction — free — Resolve an address or place to a LocalProof jurisdiction and coverage state. - localproof.get_coverage — free — Return jurisdiction and source coverage without running paid research. - localproof.get_source_catalog — free — Return authoritative public sources and freshness expectations for a jurisdiction. - localproof.get_source_health — free — Probe the currently registered official sources for a jurisdiction and report reachability without returning source records. - localproof.check_local_changes — $0.01 USD — Find material local permit-record changes for a resolved property since a caller-supplied timestamp. - localproof.check_property_changes — $0.03 USD — Find timestamped changes across released evidence dimensions for a resolved property since a caller-supplied timestamp, with deterministic change fingerprints, source-snapshot digests, per-source observational summaries, explicit timestamp semantics, source gaps, and a machine-readable next-check contract for repeat polling. - localproof.check_permits — $0.09 USD — Reconcile current official permit records for a resolved property. - localproof.check_permit_routing — $0.25 USD — Trace official San Francisco building-permit review routing, departments, holds, timing, and recorded review results for a resolved property. - localproof.check_property — $0.06 USD — Resolve a property and return a source-backed local-government context snapshot. - localproof.check_parcel_context — $0.06 USD — Return a privacy-minimized official parcel context record, including released land-use, physical-property, zoning, and assessor attributes for jurisdictions with a supported parcel source. - localproof.check_planning_activity — $0.25 USD — Reconcile planning applications and entitlement activity for a property. - localproof.check_code_enforcement — $0.25 USD — Reconcile available code-enforcement and complaint records for a property. - localproof.check_zoning_context — $0.01 USD — Resolve official San Francisco zoning and height-district context for a property point, with Planning Department source provenance and boundary limitations. - localproof.property_intelligence_pack — $0.25 USD — Create a reconciled multi-source property intelligence package with explicit completeness, source gaps, official-source provenance manifest, machine-readable continuation calls, and repeat-poll guidance through check_property_changes. - localproof.site_selection_compare — $0.49 USD — Compare two or three candidate San Francisco sites across the same released permit, planning, enforcement, and zoning evidence dimensions, with bounded evidence highlights, completeness metadata, source gaps, official-source provenance manifests, and machine-readable drilldowns, without selecting a winner. - localproof.development_due_diligence — $2.95 USD — Build an expanded San Francisco development due-diligence evidence package with cross-source chronology, administrative attention items, explicit completeness and source gaps, official-source provenance manifest, machine-readable continuation calls, repeat-poll guidance through check_property_changes, and interpretation boundaries. Paid results include an additive davisville-receipt-envelope.v1 with hashed request/subject binding, settlement metadata, deterministic Delivery conformance, bounded evidence references, and content-integrity digest. The native LocalProof result remains authoritative for evidence and source semantics.
