Comfyui Mcp Server
Let your coding agent trigger ComfyUI image and generative workflows as MCP tools instead of clicking nodes manually.
Overview
ComfyUI MCP Server is a Build-phase MCP server that maps ComfyUI workflows to tools callable by your AI coding host.
What is this MCP server?
- Turns saved ComfyUI workflows into MCP tools your host can list and invoke
- npm package `@metabrain-labs/comfyui-mcp-server` at version 1.0.1
- stdio transport for standard Claude Code and Cursor MCP configs
- TypeScript implementation repo ComfyUI-MCP-Server-TypeScript on GitHub
- Designed for MCP Host discovery—no custom ComfyUI HTTP scripts per task
- Registry version 1.0.1
- npm identifier `@metabrain-labs/comfyui-mcp-server` with stdio transport
- Single-package MCP registry entry io.github.MetaBrain-Labs/comfyui-mcp-server
Community signal: 9 GitHub stars.
What problem does it solve?
You already invested in ComfyUI graphs but every tweak still means manual UI work disconnected from your agent session.
Who is it for?
Solo builders with a local or LAN ComfyUI setup who want Cursor or Claude Code to run generation workflows as MCP tools.
Skip if: Builders with no ComfyUI instance, or teams that only need a hosted image API with zero graph maintenance.
What do I get? / Deliverables
After registration, your MCP host can invoke named tools that execute ComfyUI workflows without you driving the node editor each time.
- MCP tool surface mirroring selected ComfyUI workflows
- Agent-invokable generation runs without manual graph editing each time
- Repeatable stdio MCP entry documented in your project setup
Recommended MCP Servers
Journey fit
ComfyUI bridges sit on Build because they connect a running creative pipeline to the agent stack during product development. integrations is the right shelf for MCP servers that wrap an external runtime (ComfyUI) into host-callable tools.
How it compares
MCP bridge to ComfyUI workflows, not a bundled diffusion model or a markdown-only skill.
Common Questions / FAQ
Who is ComfyUI MCP Server for?
Developers and creators who already use ComfyUI and want their coding agent to trigger those workflows through standard MCP tool calls.
When should I use ComfyUI MCP Server?
Use it while building or refreshing visual assets when agent-driven batch runs beat manual node edits in the ComfyUI UI.
How do I add ComfyUI MCP Server to my agent?
Install `@metabrain-labs/comfyui-mcp-server` from npm, add an stdio MCP server block in your host config, and point it at your running ComfyUI endpoint per the repo README.
