CADCraft and AI agents (MCP)
CADCraft speaks the Model Context Protocol over stdio.
Start it
# Headless: an in-process drawing session, no window.
cadcraft-cli mcp
# Bridged to the running app (watch the agent draw):
cadcraft --control 7979 &
cadcraft-cli mcp --connect 127.0.0.1:7979
Example client configuration (Claude Code / Claude Desktop):
{ "mcpServers": { "cadcraft": { "command": "cadcraft-cli", "args": ["mcp"] } } }
Tools
| Tool | What it does |
|---|---|
command_line {text} |
Type at the command line exactly like a person: line 0,0 @10,0 @0,5 c, circle 5,2 1, offset 0.5, zoom e. Spaces act as Enter; empty text is Enter. Returns the new prompt, keywords and output. |
script {text} |
A multi-line script (like .scr files). |
execute {command, params} |
Any command with JSON parameters, never a dialog. list_commands shows ids and parameter docs. |
list_commands {filter?} |
The command catalog. |
inspect_drawing {entities?, limit?} |
Counts, extents, layers, styles, blocks, layouts, selection, undo history and entities. |
query_entities {type?, layer?, window?} |
Filtered entities with handles and geometry. |
render {width?, height?, fit?} |
A PNG image of the drawing. |
new_drawing {metric?}, open {path}, save {path?}, cancel |
Files and Escape. |
screenshot, ui_inspect, ui_click {x, y} |
Only when connected to the app. |
Resources: cadcraft://drawing (inspect JSON) and cadcraft://commands (catalog).
A typical session
command_line {"text": "rectang 0,0 100,60"}execute {"command": "circle", "params": {"center": [10, 10], "radius": 4}}command_line {"text": "dimlinear 0,0 100,0 50,-8"}inspect_drawing {}— verify counts and geometry.render {}— look at it.
The end-to-end test in crates/mcp/src/tests.rs runs a session like this and checks the result
only through MCP.
