What is installer-packs?

A manifest-based setup package for ComfyUI, a tool for building image-generation workflows. Each package combines required extensions, downloaded model files, setup scripts, and a workflow to load.

Use it to install a model family in ComfyUI, create setup packages from an installer or workflow, and provide Windows or RunPod installation scripts.

It removes the need to find and install each extension and model separately. The manifest records the setup once and can skip files that are already installed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00056	$0.00932
Opus 5	$0.00028	$0.00466
Sonnet 5	$0.00011	$0.00186

Security

Grade A, and why

installer-packs scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Installer Packs

comfyui-mcp ships installer packs under packs/ — one-command setups for a model family: custom nodes + model weights + a ready workflow. Each pack is driven by a single manifest.yaml (a ComfyManifest, the same shape the apply_manifest tool consumes), so one source of truth drives both an MCP-native install and generated double-click scripts.

packs/<name>/
  manifest.yaml         # custom_nodes + models (url → local_path) — source of truth
  pack.yaml             # metadata: workflow, family, VRAM, sources, notes
  workflow.json         # the graph to load
  install-windows.bat   # GENERATED — never hand-edit
  install-runpod.sh     # GENERATED — never hand-edit

Installing a pack

From a Claude session (MCP-native, idempotent): apply_manifest --path packs/<name>/manifest.yaml (requires COMFYUI_PATH). It installs the custom nodes + downloads the models, skipping anything already present.
One-click for non-MCP users: run packs/<name>/install-windows.bat (or install-runpod.sh) from a ComfyUI root. Then load the pack's workflow.json.
After install, check the pack's pack.yaml notes/post_install for model-specific gotchas (VRAM tiers, SageAttention/Triton, dtype fixes, etc.).

Building or deriving a new pack

Two sources of ground truth, in order of preference:

An upstream installer (*-MODELS-NODES_INSTALL.bat / .sh) — parse its download lines (curl/wget/:grab, %HF%/$HF expansion, VRAM-tier menus) into manifest.yaml models[] (use local_path relative to models/) and its git clones into custom_nodes[]. Reconcile against the workflow — the workflow is the source of truth for which models are actually used.
A workflow alone (no installer) — extract every model filename from the workflow's widgets_values, then resolve each to its canonical Hugging Face resolve/main URL and verify it's live (the CI URL check will too). Never invent a URL — flag what you can't resolve. Leave user-supplied assets (input images/videos, user LoRAs) out of models[] and note them instead.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
