Claude Code: ask. ### `compare_drapes` - The name "compare_drapes" says "compare": a word for reading. - The server marks it as not read-only (readOnlyHint: false). - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text 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_layout` - The name "create_layout" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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_workspace` - The name "create_workspace" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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 The ID and upload/download links grant access; do not publish them. ``` ### `export_pattern` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `import_part` - The name "import_part" says "import": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `load_sample` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Register a built-in sample and return a mesh_id for draping. ``` ### `run_drape` - The name "run_drape" says "run": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `select_faces` - The name "select_faces" says "select": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create a drapable mesh from explicitly chosen STEP face IDs; reports connectedness. ``` ### `suggest_seed` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Suggest a starting point on a mesh. Validate its coverage with an actual drape. ``` ## Only reads (7) Looks things up and changes nothing. Claude Code: allow. ### `get_job` - The name "get_job" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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_fabrics` - The name "list_fabrics" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List fabric IDs, nominal locking angles, tow pitch (mm), thickness and UD settings. ``` ### `list_faces` - The name "list_faces" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `list_samples` - The name "list_samples" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List built-in example parts that can be loaded without uploading a file. ``` ### `list_uploads` - The name "list_uploads" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List files uploaded through this workspace's upload_url; pass an upload_id to import_part. ``` ### `mesh_landmarks` - The description's first verb is "inspect": a word for reading. Description, as the server wrote it: ```untrusted-server-text Inspect 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. ``` ### `server_status` - The name "server_status" says "status": a word for reading. Description, as the server wrote it: ```untrusted-server-text Check the hosted DrapeCut solver and read connection/workspace limits. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `drapecut`: ```json { "permissions": { "allow": [ "mcp__drapecut__list_uploads", "mcp__drapecut__get_job", "mcp__drapecut__list_fabrics", "mcp__drapecut__list_faces", "mcp__drapecut__list_samples", "mcp__drapecut__mesh_landmarks", "mcp__drapecut__server_status" ], "ask": [ "mcp__drapecut__create_workspace", "mcp__drapecut__compare_drapes", "mcp__drapecut__create_layout", "mcp__drapecut__export_pattern", "mcp__drapecut__import_part", "mcp__drapecut__load_sample", "mcp__drapecut__run_drape", "mcp__drapecut__select_faces", "mcp__drapecut__suggest_seed" ], "deny": [] } } ```
