LINE, POINT and POLYLINE3D points take z. ``` ### `cad_create_block` - The name "cad_create_block" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Defines a reusable Block containing geometric entities and optional attribute definitions (ATTDEF). ``` ### `cad_execute_script` - The name "cad_execute_script" says "execute": a word for a change. - The input takes a statement or command to run (input.script), which can change anything it can reach. Description, as the server wrote it: ```untrusted-server-text Executes JavaScript to generate large or procedural geometry (loops, patterns, algorithms) without spending context tokens. Runs in a separate Node process that cannot write files, start programs or read anything outside the CAD sources; 30 s limit. Variables: CAD, M (CADMath), G (CADGeometry), E (CADEntities), S (CADState), D (CADDXF), L (CADLayouts), parametric, solid(recipe) (adds a 3D solid), console. Changes to the drawing are kept. ``` ### `cad_export_dxf` - 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 Exports the current drawing to a standard AutoCAD 2000 (AC1015) ASCII DXF file compatible with AutoCAD, Civil 3D, SolidWorks, and LibreCAD. ``` ### `cad_export_stl` - 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 Exports the closed 3D solids to a binary or ASCII STL file for 3D printing. ``` ### `cad_export_svg` - 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 Renders the drawing or paper space layout to an SVG vector file for instant preview and inspection. ``` ### `cad_generate_parametric` - The name "cad_generate_parametric" says "generate": a word for a change. Description, as the server wrote it: ```untrusted-server-text Generates complex parametric structures: "structural_grid", "truss", "mechanical_flange", "gear", or "architectural_floorplan". ``` ### `cad_insert_block` - The name "cad_insert_block" says "insert": a word for a change. Description, as the server wrote it: ```untrusted-server-text Places an instance (INSERT) of a block into the drawing with transform scale, rotation, and attribute values. ``` ### `cad_new_drawing` - 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 Initializes a fresh CAD drawing space, clearing existing entities and resetting layers. ``` ### `cad_open_dxf` - The name "cad_open_dxf" says "open": a word for a change. Description, as the server wrote it: ```untrusted-server-text Opens an existing ASCII DXF file (AutoCAD R12 to 2018+) in place of the current drawing, so it can be edited with cad_run_commands and saved with cad_export_dxf. Returns counts, what was converted, and a warning listing objects that cannot be read (they would be missing from a saved file). ``` ### `cad_open_shared` - The name "cad_open_shared" says "open": a word for a change. Description, as the server wrote it: ```untrusted-server-text Opens a shared drawing from Cloudflare D1 storage into the current CAD session by its share ID or URL. ``` ### `cad_run_commands` - The name "cad_run_commands" says "run": a word for a change. Description, as the server wrote it: ```untrusted-server-text Runs AutoCAD command-line input in the current drawing, exactly as typed in the app. Statements are separated by ";" or newlines; inside a statement tokens are separated by spaces and the statement ends with Enter. Example: "LINE 0,0 100,0 100,50; CIRCLE 50,25 10; CHPROP ALL; C red; LAYMRG N DOORS; N WALLS Y; DRAWORDER ALL; F". Every statement ends with Enter, so keep the follow-up answers of one command step in the same statement ("CHPROP ALL; LA WALLS C red"; a question asked after Enter goes in the next statement: "LAYDEL N TEMP; Y"). Objects are selected with ALL or P (previous). Returns the command log and any problems. 3D: points x,y,z; 3DPOLY, ELEV, VIEW (Top, Front, SWiso ...), UCS. 3D solids: BOX, CYL, SPHERE, EXTRUDE, REVOLVE, UNION, SUBTRACT, INTERSECT, MASSPROP. Use cad_list_commands to see every command. ``` ### `cad_share_drawing` - Nothing in its name or description says what it does, so it is counted as a write.

Returns view and edit URLs that can be shared with users or other agents. ``` ### `cad_update_shared` - The name "cad_update_shared" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text Uploads and updates the current CAD session drawing to an existing shared drawing using its editToken. ``` ## Only reads (3) Looks things up and changes nothing. Claude Code: allow. ### `cad_get_stats` - The name "cad_get_stats" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Returns comprehensive statistics of the current drawing: entity count, breakdown by type, layers, bounding box extents, blocks, and layouts. ``` ### `cad_list_commands` - The name "cad_list_commands" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text Lists every implemented AutoCAD command with its aliases and description. Optional filter matches the name, an alias or words in the description (for example "layer" or "dim"). ``` ### `cad_solids` - The description's first verb is "inspect": a word for reading. Description, as the server wrote it: ```untrusted-server-text Inspects 3D solids: list (id, op, volume, bounds), measure (volume, area, centroid) or check (closed, curve error). ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `autocad-site`: ```json { "permissions": { "allow": [ "mcp__autocad-site__cad_list_commands", "mcp__autocad-site__cad_solids", "mcp__autocad-site__cad_get_stats" ], "ask": [ "mcp__autocad-site__cad_new_drawing", "mcp__autocad-site__cad_add_layers", "mcp__autocad-site__cad_batch_add_entities", "mcp__autocad-site__cad_create_block", "mcp__autocad-site__cad_insert_block", "mcp__autocad-site__cad_generate_parametric", "mcp__autocad-site__cad_run_commands", "mcp__autocad-site__cad_execute_script", "mcp__autocad-site__cad_open_dxf", "mcp__autocad-site__cad_export_dxf", "mcp__autocad-site__cad_export_svg", "mcp__autocad-site__cad_export_stl", "mcp__autocad-site__cad_share_drawing", "mcp__autocad-site__cad_open_shared", "mcp__autocad-site__cad_update_shared" ], "deny": [ "mcp__autocad-site__cad_revoke_shared" ] } } ```
