    How to connect

    How to connect DrapeCut to Claude

    The server address to paste into Claude settings:

    https://drapecut.com/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect DrapeCut to ChatGPT

    The server address to paste into ChatGPT settings:

    https://drapecut.com/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    How to connect DrapeCut to Cursor

    The server address to paste into Cursor settings:

    https://drapecut.com/mcp

    Fastest: click Open in Cursor below and confirm the prompt.

    Manually:

    1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
    2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
    3. Save the file. The server appears in the MCP list; authorize it there if asked.

    Authorization

    If the service needs sign-in, an authorize button appears next to the server in the MCP list.

    Server tool list (16)

    Raw names from tools/list. Only developers need these.

    create_workspaceCreate 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.
    list_uploadsList files uploaded through this workspace's upload_url; pass an upload_id to import_part.
    compare_drapesCompare 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. 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.
    export_patternExport 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.
    get_jobPoll 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.
    import_partImport 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.
    list_fabricsList fabric IDs, nominal locking angles, tow pitch (mm), thickness and UD settings.
    list_facesInspect 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.
    list_samplesList built-in example parts that can be loaded without uploading a file.
    load_sampleRegister a built-in sample and return a mesh_id for draping.
    mesh_landmarksInspect seed landmarks in mm, paged within each category (max 100 per category). Returns centre, corners, edge midpoints and origin intersections. Full section polylines are omitted. Follow next_offset for more points.
    run_drapeDrape 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.
    select_facesCreate a drapable mesh from explicitly chosen STEP face IDs; reports connectedness.
    server_statusCheck the hosted DrapeCut solver and read connection/workspace limits.
    suggest_seedSuggest a starting point on a mesh. Validate its coverage with an actual drape.
