# cao_demo WHEN you are about to draw ANY French building for the first time, or when a user asks for a plan / DXF / IFC and you have not yet used these tools — call this FIRST. It hands back a COMPLETE, ALREADY-VERIFIED scene (zero audit alerts) plus the exact next calls in order. FREE, no API key, 0 units. WHY IT MATTERS: composing a scene from the schema alone takes several round-trips and usually fails on the same mistakes (openings.z used as an absolute altitude instead of a relative sill, a storey with no windows). Starting from a working scene and editing it is faster and cannot fail. GOOD CALL: cao_demo {} -> the house; cao_demo {"exemple": "appartement"} for a flat with no roof; cao_demo {"exemple": "extension"} for a veranda grafted onto an existing facade. Then feed scene straight into cao_verifier, then cao_pdf / cao_generer_dxf / cao_generer_ifc. DO NOT: do not invent a scene from scratch before trying this; do not call it to CHECK a scene you already have (that is cao_verifier); do not expect a drawing back — this returns JSON, the drawing comes from the next call. All dimensions are MILLIMETRES. Agent View of the PolicyLayer registry record for `cao_demo`.

Every call changes real data in your Immobilier environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Immobilier: ```json { "version": "1", "default": "deny", "tools": { "cao_demo": { "limits": [ { "counter": "cao_demo_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Immobilier (69) - `cao_energie` — Destructive — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-energie.md - `cao_nomenclatures` — Destructive — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-nomenclatures.md - `cao_verifier` — Destructive — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-verifier.md - `cao_bibliotheque_familles` — Execute — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-bibliotheque-familles.md - `cao_carnet` — Execute — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-carnet.md - `cao_generer_ifc` — Execute — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-generer-ifc.md - `cao_livrer` — Execute — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-livrer.md - `cao_visite_camera` — Execute — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-visite-camera.md - `bonnes_pratiques` — Read — https://policylayer.com/tools/fr-synergieloc-immobilier/bonnes-pratiques.md - `cao_4d` — Read — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-4d.md - `cao_devis` — Read — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-devis.md - `cao_familles` — Read — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-familles.md - `cao_ids_verifier` — Read — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-ids-verifier.md - `cao_pdf` — Read — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-pdf.md - `cao_rendu` — Read — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-rendu.md - `cao_urbanisme` — Read — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-urbanisme.md - `pack_partenaire` — Read — https://policylayer.com/tools/fr-synergieloc-immobilier/pack-partenaire.md - `annonce_location` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/annonce-location.md - `avenant_revision_irl` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/avenant-revision-irl.md - `avis_echeance` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/avis-echeance.md - `bon_intervention` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/bon-intervention.md - `candidature_locataire` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/candidature-locataire.md - `cao_bcf_ifc` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-bcf-ifc.md - `cao_comparer_versions` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-comparer-versions.md - `cao_conflits_ifc` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-conflits-ifc.md - `cao_copilote` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-copilote.md - `cao_documents` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-documents.md - `cao_famille_essayer` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-famille-essayer.md - `cao_familles_recharger` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-familles-recharger.md - `cao_ferraillage` — Write — https://policylayer.com/tools/fr-synergieloc-immobilier/cao-ferraillage.md - …and 39 more: https://policylayer.com/tools/fr-synergieloc-immobilier.md ## For agents This record is a snapshot.
