README

mcp-comfy-ui-builder

ComfyUI Node Discovery — seed knowledge base and MCP tools for Cursor/Claude.
Publishable to the MCP Registry via server.json and mcpName.

What is this

Knowledge base: Seed knowledge/base-nodes.json and node-compatibility.json from bundled data (62 seed nodes; 100–600+ after sync). No external services required for suggest/build.
Sync: Custom packs from ComfyUI-Manager; nodes from running ComfyUI via sync-nodes CLI or on MCP startup.
MCP server (50+ tools): Node discovery, dynamic workflow builder, 9 templates (txt2img, txt2img_flux, img2img, …), WebSocket real-time execution, batch/chain, model management, plugin system.
Real-time execution: Sub-second progress via WebSocket with automatic polling fallback; ~90% less network traffic for batch runs.

Install

npm install mcp-comfy-ui-builder

Or from source: git clone https://github.com/MIt9/mcp-comfy-ui-builder.git && cd mcp-comfy-ui-builder && npm install

Quick start

Build (postbuild fills knowledge from seed)
```
npm run build
npm run mcp
```

Use knowledge in code

import baseNodes from './knowledge/base-nodes.json' assert { type: 'json' };

Commands

Command	Description
`npm run seed`	Fill knowledge from seed. Use `--force` to overwrite.
`npm run sync-manager`	Update custom packs list from ComfyUI-Manager
`npm run sync-nodes`	Sync nodes from running ComfyUI to knowledge base (requires COMFYUI_HOST)
`npm test`	Run tests (vitest)
`npm run mcp`	Start MCP server (after `npm run build`)
