# cao_soleil

WHEN a design decision depends on the SUN: how many hours of direct sunlight each window actually receives, where the building casts its shadow on the plot, and whether a neighbouring building or screen blocks the light. From the CAO scene, for the three dates that decide a project (21 June, 21 March, 21 December): sunrise, sunset, maximum altitude, the shadow at solar noon (area and outline), and per window the hours of sun with the first and last hour, its orientation and its azimuth. Obstacles are the building's own walls and roof plus any masques you declare. The site comes from georef (Lambert-93); without it Strasbourg is used and the answer says so. No solar gain in watts and no RE 2020 discomfort hours: those need a dynamic thermal engine.

- Parameters: 12
- Recommended policy verdict: Rate-limited

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `murs` | array | no | 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 | no | 2D reference lines — drawn flat, never extruded and never counted in the quantities. Use them for axes, plot limits or setting-out marks. |
| `annee` | integer | no | Optional year for the three reference dates. |
| `boites` | array | no | Boxes (furniture, volumes): a rectangular block placed by its CENTRE, not by a corner. Millimetres, same frame as murs[]. |
| `georef` | object | no | 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 | no | 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 | no | Plumbing pipe runs (EF/EC/EU/EV/EP/chauffage) — used only by cao_pdf (technical plan + linear-meter quantities per type). |
| `nord_deg` | number | no | Direction of north in the scene, in degrees clockwise from +y (0 means +y is north). |
| `toitures` | array | no | 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 |
| `plomberie` | array | no | Sanitary fixtures (sink, WC, shower…) — used only by cao_pdf. Same positioning as electricite. |
| `decoration` | array | no | Paint/finish per wall — used only by cao_pdf. Colors the elevations (exterior face) and the axonometric view (face auto-detected by orientation relative to the |
| `ouvertures` | array | no | Doors/windows embedded in a wall — used only by cao_pdf (elevations + axonometric view), no effect on dxf/metres. |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "cao_soleil",
    "arguments": {}
  }
}
```

## Why cao_soleil is rated Medium

An AI agent can call cao_soleil 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.

Risk signals: High parameter count (97 properties)

## Use case

AI agents use cao_soleil 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Immobilier:
