## Quality 73/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2024-11-05; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: cad_export_stl (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cad_batch_add_entities (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cad_run_commands (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 3,811 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 5 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know autocad-site-mcp@0.2.1

- tools: 19, about 3,811 tokens to load them all
- tool set hash: 9706fb1cfcb771fc26e32dc1edf0f476
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.blackmoon87/autocad-site-mcp.svg)](https://protogrid.dev/servers/io.github.blackmoon87/autocad-site-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (19)

- `cad_add_layers`: Creates or configures CAD layers with custom colors (hex), linetypes (Continuous, Hidden, Center, Phantom), and lineweights (0.18, 0.25, 0.35, 0.50, etc.).
- `cad_batch_add_entities`: Fast batch insertion of multiple CAD entities (LINE, LWPOLYLINE, CIRCLE, ARC, ELLIPSE, XLINE, RAY, DONUT, SOLID, TRACE, WIPEOUT, SPLINE, ARRAY (associative rect/polar/path), MLINE (multiline), TABLE (title, header and data cells), IMAGE (picture embedded in the drawing), TEXT, MTEXT, DIMENSION, TOLERANCE, LEADER, HATCH (pattern or gradient), POINT, INSERT, POLYLINE3D). LINE, POINT and POLYLINE3D points take z.
- `cad_create_block`: Defines a reusable Block containing geometric entities and optional attribute definitions (ATTDEF).
- `cad_execute_script`: 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`: Exports the current drawing to a standard AutoCAD 2000 (AC1015) ASCII DXF file compatible with AutoCAD, Civil 3D, SolidWorks, and LibreCAD.
- `cad_export_stl`: Exports the closed 3D solids to a binary or ASCII STL file for 3D printing.
- `cad_export_svg`: Renders the drawing or paper space layout to an SVG vector file for instant preview and inspection.
- `cad_generate_parametric`: Generates complex parametric structures: "structural_grid", "truss", "mechanical_flange", "gear", or "architectural_floorplan".
- `cad_get_stats`: Returns comprehensive statistics of the current drawing: entity count, breakdown by type, layers, bounding box extents, blocks, and layouts.
- `cad_insert_block`: Places an instance (INSERT) of a block into the drawing with transform scale, rotation, and attribute values.
- `cad_list_commands`: 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_new_drawing`: Initializes a fresh CAD drawing space, clearing existing entities and resetting layers.
- `cad_open_dxf`: 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`: Opens a shared drawing from Cloudflare D1 storage into the current CAD session by its share ID or URL.
- `cad_revoke_shared`: Revokes and deletes a shared drawing from Cloudflare D1 storage using its ownerToken.
- `cad_run_commands`: 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`: Shares the current drawing online via Cloudflare D1 storage (autocad.site). Returns view and edit URLs that can be shared with users or other agents.
- `cad_solids`: Inspects 3D solids: list (id, op, volume, bounds), measure (volume, area, centroid) or check (closed, curve error).
- `cad_update_shared`: Uploads and updates the current CAD session drawing to an existing shared drawing using its editToken.
