    • Warn

      The server marks "compare_drapes" as not read-only (readOnlyHint: false), and its words say it reads.

      Matched text

      annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "compare_drapes" says "compare": a word for reading.

      What this check looks for
    Description, as the server wrote it
    Compare up to 12 warp angles, sequentially, at one fixed seed and cloth configuration. When omitted, seed is suggested once for the first angle. Results rank by coverage descending, then percentage above lock ascending, then maximum shear ascending. This is a stated comparison rule, not a global optimum. Runs use the requested/preset pitch, never a hidden coarse approximation. Export the chosen result promptly: backend result IDs are temporary.

  • create_layoutStart covering one surface with multiple pieces of the same ply/fabric.No findings

    Why it is in this group

    • The name "create_layout" says "create": a word for a change.
    Description, as the server wrote it
    Start covering one surface with multiple pieces of the same ply/fabric. This is not a laminate stack. overlap is mm; supplied seeds are laid first and additional pieces fill remaining ground, up to max_pieces. Poll the returned job_id with get_job(kind='layout'); export with layout=true.

  • create_workspaceCreate a private two-hour workspace and return its ID and CAD upload page.No findings

    Why it is in this group

    • The name "create_workspace" says "create": a word for a change.
    Description, as the server wrote it
    Create a private two-hour workspace and return its ID and CAD upload page. Start here before loading a sample or importing a user's CAD part. The ID and upload/download links grant access; do not publish them.

    Annotations the server declares

    • destructiveHint: false
    • openWorldHint: false
  • export_patternExport a built-in example as DXF or tiled 1:1 PDF and return a temporary download_url.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Export a built-in example as DXF or tiled 1:1 PDF and return a temporary download_url. Uploaded-part exports require the signed-in website or an authenticated local adapter; this hosted workspace cannot be linked to a website account. Use layout=true with a layout_id to export all example pieces. Download before workspace expiry.

    Annotations the server declares

    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: false
    • readOnlyHint: false
  • import_partImport a file already uploaded to this workspace.No findings

    Why it is in this group

    • The name "import_part" says "import": a word for a change.
    Description, as the server wrote it
    Import a file already uploaded to this workspace. Get upload_id from list_uploads. STEP/STP returns a job to poll with get_job(kind='step'), then inspect and select faces.

    Description, as the server wrote it
    Register a built-in sample and return a mesh_id for draping.

  • run_drapeDrape one fabric at one warp angle (degrees); return statistics and an exportable result_id.No findings

    Why it is in this group

    • The name "run_drape" says "run": a word for a change.
    Description, as the server wrote it
    Drape one fabric at one warp angle (degrees); return statistics and an exportable result_id. Omitted seed is suggested on the surface. Omitted pitch/lock_angle use the fabric preset, including its UD spread/compression settings. pitch/offset are mm; hole_area is mm² (null bridges holes). The API may increase pitch to bound the grid; pitch_used reports the actual resolution. Kinematic shear/locking statistics are not a structural strength calculation.

    Why it is in this group

  • get_jobPoll STEP import or multi-piece layout; retry after a short delay while done=false.No findings

    Why it is in this group

    • The name "get_job" says "get": a word for reading.
    Description, as the server wrote it
    Poll STEP import or multi-piece layout; retry after a short delay while done=false. STEP completion returns a step_id and at most 20 basic face descriptions; use list_faces for geometric descriptions and pagination. Layout completion returns compact per-piece statistics and a layout_id for export_pattern.

  • list_facesInspect STEP face IDs, areas, bounds, centroids, neighbours and planar mesh normals.No findings

    Why it is in this group

    • The name "list_faces" says "list": a word for reading.
    Description, as the server wrote it
    Inspect STEP face IDs, areas, bounds, centroids, neighbours and planar mesh normals. This requires the MCP face-metadata endpoint in the configured backend. Centroids/bounds describe the tessellation; do not assume a closed solid's entire skin is the intended draping surface. Ask for explicit face IDs when the intended surface cannot be identified from this information.

    Description, as the server wrote it
