Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • analyze_floorplan_imageAnalyze floor-plan imageread-only

    Defer to the MCP host (via sampling) to extract walls, rooms, and approximate dimensions from a floor-plan image. Requires host support for sampling.

  • analyze_room_photoAnalyze room photoread-only

    Defer to the MCP host (via sampling) to extract approximate dimensions, fixtures, and windows from a single-room photograph. Requires host support for sampling.

  • apply_patchApply patchcan change or delete data

    Apply a batch of create/update/delete operations atomically. All patches are validated before any are applied; the entire batch forms a single undo step. Batch-first is the default: prefer one apply_patch call containing all create/update/delete ops for a build step, in stable order so later ops can reference ids created by earlier ops. A single call is atomic (all or nothing) and pays the snapshot and save cost once; do not loop one-op calls. A create whose id already exists fails the whole patch with node_exists; to replace a node, delete it earlier in the same patch. An update cannot change…

  • check_collisionsCheck collisionsread-only

    Assess declared item footprints with a rotation-aware plan AABB test. Supports an explicit minimum clearance and reports units, source dimensions, skipped evidence, and unsupported checks. Optionally scope to one level or floor-standing items.

  • create_from_templateCreate scene from templatecan change or delete data

    Instantiate a seed Pascal scene template into the bridge. Regenerates all ids before applying. When `save: true` and a SceneStore is wired, also persists the new scene and returns the SceneMeta.

  • create_house_from_briefCreate house from briefcan change or delete data

    High-level hosted workflow for external agents: choose a starter house from a brief, create/save/publish it, and return the editor URL. Use semantic tools afterward for exact customization.

  • create_projectCreate project

    Create a browser-visible Pascal project for the authenticated user. Use this before save_scene when the user asks for a new project.

  • create_story_shellCreate story shell

    Create one level-owned building shell from a footprint: the perimeter walls. The floor plate and the ceiling are DERIVED from the rooms the walls enclose — never author a slab or a ceiling here, and never pass boundary/autoFromWalls; createSlab / createCeiling / slabElevation are recorded as room intent instead. Use once per story; do not make first-floor walls span multiple stories.

  • create_unitCreate unit

    Create a named unit in a building, optionally referencing zones across its levels.

  • delete_sceneDelete scenecan change or delete data

    Remove a stored scene by id. In Pascal this never deletes the project: it hides it from Pascal's public listings until it is next saved with content, and answers `deleted: false, hidden: true` with a message; its owner can delete it from the projects page. Only someone who can manage the project may hide it. A local scene store deletes the scene. Optionally pass `expectedVersion` for optimistic concurrency.

  • export_glbExport GLBread-only

    GLB export is not available in headless mode — it requires the Three.js renderer, which is browser-only. Returns a structured `not_implemented` tool error.

  • export_jsonExport JSONread-only

    Return the scene as a serialized JSON string. Pass `pretty: true` to indent with 2 spaces.

  • generate_variantsGenerate variants

    Generate N variations of a base scene by forking and applying seeded mutations. Example: "give me 5 variations of this kitchen". If `save=true`, each variant is persisted via scene operations and returned with an id + URL; otherwise the graph is returned inline.

  • get_project_statusGet project statuscan change or delete data

    Authoritative status/debug call for a Pascal project: editor URL, browser-visible version, latest saved version, published version, node count, and graph hash.

  • get_sceneGet sceneread-only

    Returns the full scene graph: flat node dictionary, root node IDs, collections, and explicit installed plugin IDs when present.

  • list_scenesList scenesread-only

    List scenes in the SceneStore. Optionally filter by `projectId` and cap results with `limit` (default 100).

  • list_templatesList scene templatesread-only

    List the seed Pascal scene templates available to `create_from_template`. Returns the id, display name, one-line description and node count for each.

  • list_unitsList unitsread-only

    List units with their member zones and current area reports, optionally filtered by building.

  • load_sceneLoad scenecan change or delete data

    Load a scene from the SceneStore into the bridge. Returns the scene metadata. Throws `scene_not_found` if the id does not exist.

  • measureMeasureread-only

    Measure the distance (in meters) between two nodes, or the net area of a polygon node when fromId === toId. Distance is between world-space reference points, returned as fromPoint/toPoint: a positioned node's origin in its host's frame (an item's base, a door's or window's centre in its wall), a wall's or fence's midpoint at its base, a slab's, ceiling's or zone's polygon centroid on its plane, a block's or imported mesh's vertex-bounds centre, a level's plan centre on its base plane, and another container's descendants' centre. `approximate` lists nodes whose renderer derives the pose from da…

  • photo_to_scenePhoto to Pascal scenecan change or delete data

    Orchestrator: analyse a floor-plan photo via MCP sampling, translate the structured vision result into a Pascal SceneGraph (site → building → level with walls and zones), optionally save it, and swap the bridge to the new scene. Requires host support for sampling.

  • redoRedocan change or delete data

    Redo the next N previously-undone steps (default 1). Returns the number of steps actually redone.

  • rename_sceneRename scenecan change or delete data

    Rename a scene in the SceneStore. Returns the updated SceneMeta. Optionally pass `expectedVersion` for optimistic concurrency.

  • save_sceneSave scenecan change or delete data

    Save the current scene (or a provided graph) to the SceneStore. Without id or projectId it saves to the project this session is bound to (create_project or load_scene). Defaults to a browser-visible draft save so agents can iterate without creating many project versions. Use saveMode: "checkpoint" for meaningful version history.

  • set_unit_membersSet unit memberscan change or delete data

    Replace the zones referenced by a unit. Every zone must belong to a level in the same building.

  • set_zoneSet zone

    Create a polygonal zone on the given level. label is stored as the zone name and properties are merged into metadata. A polygon along walls that already enclose a room is that room, never a second zone: a room still named "Room N", or already named label, takes the label and properties; a room a person named otherwise is refused (rename it with update_node only when the person asked).

  • undoUndocan change or delete data

    Undo the most recent N steps in the scene history (default 1). Returns the number of steps actually undone.
