What cao_livrer does on Immobilier
AI agents invoke cao_livrer to trigger actions in Immobilier. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
ids | string | — | Optional IDS (XML text) the IFC must satisfy. |
murs | array | — | Walls: plan segments extruded vertically. Every coordinate in this whole scene is in MILLIMETRES, in a single plan frame whose origin you choose — X to the righ |
plan | array | — | 2D reference lines — drawn flat, never extruded and never counted in the quantities. Use them for axes, plot limits or setting-out marks. |
auteur | string | — | Author, copied to the manifest. |
boites | array | — | Boxes (furniture, volumes): a rectangular block placed by its CENTRE, not by a corner. Millimetres, same frame as murs[]. |
georef | object | — | Optional Lambert-93 (EPSG:2154) false origin for IfcMapConversion. Local millimetres are scaled by 0.001 to CRS metres. Do not invent coordinates: omit est/nord |
cercles | array | — | Circles on the 2D plan, alongside plan[] lines: each has a centre and a radius, in the same unit as the plan. Use for round shapes a polyline would render badly |
reseaux | array | — | Plumbing pipe runs (EF/EC/EU/EV/EP/chauffage) — used only by cao_pdf (technical plan + linear-meter quantities per type). |
version | integer | string | — | Version number, copied to the manifest. |
toitures | array | — | Roofs — used only by cao_pdf. WITHOUT this field: a flat roof is auto-generated over the footprint of ALL walls (legacy default). WITH it: compose freely — each |
livrables | array | — | Deliverables to produce. Default: ifc, dxf, metres, nomenclatures. |
plomberie | array | — | Sanitary fixtures (sink, WC, shower…) — used only by cao_pdf. Same positioning as electricite. |

Why cao_livrer is rated High
cao_livrer triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

The rule that runs cao_livrer safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Immobilier, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cao_livrer, this is the rule to start with:
cao_livrer stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Immobilier, apply this rule, and every cao_livrer call is checked against it from then on.
Questions about cao_livrer
WHEN the deliverables of a project must be produced for real (IFC, DXF, drawing sheet, quantities, schedules). Runs the checks FIRST (those of cao_verifier); if any alert is critical, NOTHING is produced and exports_authorized is false. Otherwise produces the deliverables, validates the IFC (IFC 4 schema, buildingSMART rules; an IDS you provide must pass) and returns a manifest: SHA-256 of the scene (sorted JSON, compact separators — compare it with your own), SHA-256 and size of every deliverable, checks run, version, author, date. An unexplained warning forbids a PROFESSIONAL delivery (exports_professionnels_autorises) — explain it in warnings_expliques. professional_review_required lists what remains a pre-study. It is categorised as a Execute tool in the Immobilier MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
cao_livrer accepts 12 parameters: ids, murs, plan, auteur, boites, georef, cercles, reseaux, version, toitures, livrables, plomberie. The full parameter table on this page comes from the server's own tool schema.
Register the Immobilier MCP server in PolicyLayer and add a rule for cao_livrer: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Immobilier. Nothing to install.
cao_livrer is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the cao_livrer rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for cao_livrer. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
cao_livrer is provided by the Immobilier MCP server (https://synergieloc.fr/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
