What cao_regles_structure_reseaux does on Immobilier
AI agents use cao_regles_structure_reseaux to create or update resources in Immobilier, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Immobilier environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
sol | object | — | Soil assumptions for footings: {contrainte_mpa (default 0.20), hors_gel_mm (default 800)}. |
vmc | boolean | — | Generate single-flow ventilation (extract grilles, air inlets, fan, flows). |
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. |
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). |
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 |
chauffage | boolean | — | Compute room heat losses (NF EN 12831) and size radiators at 55/45 °C. |
plomberie | array | — | Sanitary fixtures (sink, WC, shower…) — used only by cao_pdf. Same positioning as electricite. |
structure | boolean | — | Generate lintels and strip footings, check slab spans. |

Why cao_regles_structure_reseaux is rated Medium
An AI agent can call cao_regles_structure_reseaux faster than any human can review: one bad instruction and it creates or modifies resources in Immobilier by the hundred, each call as confident as the last.

Attacks that exploit this kind of access
The rule that runs cao_regles_structure_reseaux 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_regles_structure_reseaux, this is the rule to start with:
cao_regles_structure_reseaux stays usable, but capped: an agent stuck in a loop can't make hundreds of changes 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_regles_structure_reseaux call is checked against it from then on.
Questions about cao_regles_structure_reseaux
WHEN a building scene must be completed with structure and building services by French rules before BIM export or quoting: lintels over openings of load-bearing walls, strip footings sized from service loads, slab span check (indicative pre-design, to be validated by a structural engineer); NF C 15-100 electrical points per room (outlets, RJ45, lighting with its switch, one smoke detector per level, panel with 30 mA RCD) and circuit count; single-flow mechanical ventilation per the 24 March 1982 decree (extract grilles in wet rooms, air inlets in dry rooms, fan, flows); drainage branches with slopes per NF DTU 60.11; water inlet and 200 L water heater placed where missing; room heat losses per NF EN 12831 and radiators sized at 55/45 °C (NF EN 442). Adds what is missing, never removes. Returns {scene, rapport, controles}; send scene to cao_generer_ifc to get IfcBeam, IfcFooting, IfcOutlet, IfcAirTerminal, IfcPipeSegment, IfcSpaceHeater…. It is categorised as a Write tool in the Immobilier MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
cao_regles_structure_reseaux accepts 12 parameters: sol, vmc, murs, plan, boites, georef, cercles, reseaux, toitures, chauffage, plomberie, structure. 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_regles_structure_reseaux: 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_regles_structure_reseaux is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the cao_regles_structure_reseaux 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_regles_structure_reseaux. 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_regles_structure_reseaux 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.
