The Cursor plugin
The weft plugin for Cursor does what the Claude Code plugin does, with the same scripts and the same MCP server: four skills you can type, one skill the agent loads on its own, and a rule that is attached whenever a .weft file is in context.
| Skill | What it does |
|---|---|
/weft-import <page.html> [out.weft] | Turns an HTML file into a Weft screen and prints what the import lost. |
/weft-export <screen.weft> [out.jsx] [--name Component] | Turns a Weft screen into a React component. |
/weft-render <screen.weft> [out.html] [--data data.json] [--tokens tokens.json] | Turns a screen into an HTML page and opens it in Cursor's built-in browser. |
/weft-figma-pull <figma link> [out.weft] | Reads a frame of a Figma file through the Figma REST API back into a Weft screen and prints what was lost. The access token comes from the FIGMA_TOKEN environment variable. |
weft-spec (not typed) | Teaches the agent the format from AGENT-SPEC.md, so it writes, patches and repairs valid markup. |
The MCP server gives the agent weft_primer, weft_catalog, weft_schema, weft_validate, weft_format, weft_patch, weft_render and weft_context. The skills read and write files through small scripts; the server never touches files. The scripts are the ones described in the Claude Code page: they never replace a file unless you pass --force, and exit with 0 (done), 1 (the input has errors) or 2 (usage or file problem).
Install
The packages run from this repository's sources, so install the plugin from a clone. First make the clone ready, as in the tour: mise install, pnpm install, moon run root:wasm. node 26.7 or later must be on the PATH that Cursor starts programs with. Then link the plugin folder into Cursor's local plugins and restart Cursor, or run Developer: Reload Window:
ln -s /path/to/weft/plugins/cursor ~/.cursor/plugins/local/weftCursor copies only the plugin folder into its cache, so the folder carries what it runs: the bundled scripts and server in dist/, with the WebAssembly core. They are built once, from plugins/shared, for this plugin and the Claude Code plugin together (moon run shared:build).
Limits
- Installing from a local clone only; the plugin is not listed in a marketplace you can add by name, and the repository has no GitHub address to import from yet.
- It has been checked by tests against Cursor's published plugin format and from a copy of the folder, but not yet inside a signed-in Cursor; the plugin's README lists what remains.
/weft-renderopens the page in the built-in browser. If that browser refuses afile://address, the agent serves the folder on localhost instead.
