What it does
Comfy MCP is an agent skill from autonomous-ai/openharness. Create and inspect generative media projects in the Comfy MCP Harness workspace, including its local starter and optional upstream integration.
Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol and ComfyUI. The repository describes itself as: The ultimate harness for coding agents and beyond. All your agents. All your machines. One command center. Start with code, then follow your curiosity and build across… The licence is MIT.
When your agent uses it
- Tasks that involve MCP servers
Example prompts
- “/comfy-mcp”
What it can do on your machine
Read from SKILL.md and the folder at commit 74c2733. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Comfy MCP loads about 526 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 269 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Variation garden
Read studio.json to understand the current controls; "$STUDIO_TOOLCHAIN/../studio.config.json"
describes their ranges. Run "$STUDIO_TOOLCHAIN/run.sh" generate to make a new result.
Successful artifacts and their measurements are in out/runs/<id>/; out/latest.json names the
current result. A failed run preserves the last success and records the error in the verdict.
The local starter creates deterministic procedural SVG artwork and a contact sheet. It is not diffusion or an AI-generated image claim. The native action submits the saved API workflow to an existing local ComfyUI, polls its result, and collects actual output images. The supplied native workflow uses no model and no paid API.
Use "$STUDIO_TOOLCHAIN/../README.md" for the integration contract and commands. Read the relevant
files under $STUDIO_UPSTREAM before using an upstream API. Keep controls within their documented
ranges, preserve the data needed to reproduce a comparison, and distinguish preview results from
native service or hardware output. The viewer supports history and artifact downloads; tell the
user which run contains the result, and what was actually measured.
Grow a reproducible family
Choose a palette and seed, run generate, then inspect each study and its saved recipe.
The SVG hashes verify reproducibility. These local vector studies do not use a diffusion
model. Keep selected studies and their seed/parameters together when making a new family.
For an installed ComfyUI, read $STUDIO_UPSTREAM/README.md and its src/ tools before
using the MCP workflow. Save API-format nodes in workspace workflow.json. The supplied
EmptyImage/SaveImage workflow needs no model weights. Run comfy against loopback
COMFYUI_URL, inspect its job history, and retain the returned PNGs. A timeout means the
remote queue may still be running; inspect it before resubmitting expensive work.
