Scope
Validates DPP required data elements against the CIRPASS-2 Core Ontology (7 mandatory fields including durability, reparability, recyclability, carbon_footprint, and substances_of_concern). Also checks the GS1 Digital Link data-carrier type. EU ESPR Central DPP Registry goes live 19 Jul 2026.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `validate_dpp_data_carrier`. Task: Validate DPP required data elements against CIRPASS-2 Core Ontology and GS1 Digital Link carrier type.
Call it with arguments: {"policy_parameters":{"product_id":"GS1-DL-8712345678901","data_carrier_type":"qr_gs1_digital_link","elements":{"unique_product_identifier":"8712345678901","lookup_mechanism":"https://id.gs1.org/01/8712345678901","durability":"10 years","reparability":"Consumer repairable — 7 spare parts available","recyclability":"95% recyclable by weight","carbon_footprint":"12.4 kgCO2e","substances_of_concern":"none declared"},"ontology_version":"CIRPASS-2-2025-03"}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
