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 | $0.01424 | $0.01424 |
| Opus 5 | $0.00712 | $0.00712 |
| Sonnet 5 | $0.00285 | $0.00285 |
| Haiku 4.5 | $0.00142 | $0.00142 |
Grade A, and why
comfyui-mcp CLAUDE.md scanned grade A with 0 findings 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 6d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.
comfyui-mcp
TypeScript MCP server (stdio) giving Claude Code 16 tools to drive ComfyUI on the spark DGX box — queue workflows, see outputs as MCP image blocks, iterate without the web UI.
Run / test
npm run build— tsc todist/.dist/index.jsis what Claude Code runs (registered as thecomfyuiserver in~/.claude.json). Rebuild after every src change; restart Claude Code to pick it up.npm test— node test runner via tsx (tests/*.test.ts+tests/tools/*.test.ts), all offline (handlers take injectable deps).npm run smoke -- --live— hits spark for real (system_stats, ssh ping, output listing). Without--liveit exits immediately.
Connection to spark
All defaults live in src/config.ts, overridable by env (set in the ~/.claude.json server entry):
COMFYUI_HOST—http://<gpu-host>:8188(HTTP for queue/view/history/stats)SPARK_SSH_ALIAS—spark(from~/.ssh/config; SSH for workflow JSON r/w, output listing, model downloads via remote aria2c, comfyscript execution)SPARK_COMFYUI_ROOT— the ComfyUI checkout on the GPU host;SPARK_COMFYUI_PYTHON— the comfyui venv python;LLAMASWAP_HOST— the llama-swap endpoint for the GPU-yield handshakeCIVITAI_API_TOKEN/HF_TOKEN— optional, for gated model downloads. Never hardcode.
Tool surface (16 tools, one file per group in src/tools/)

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.
