Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.04571 |
| Opus 5 | $0.00028 | $0.02286 |
| Sonnet 5 | $0.00011 | $0.00914 |
| Haiku 4.5 | $0.00006 | $0.00457 |
Grade A, and why
novelai-mcp-tools 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 12d 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.

novelai-mcp-tools
Instructions for the agent to follow when invoking NovelAI MCP tools from an MCP host.
When to use
Use this skill when an MCP host (Claude Desktop, Cline, or a custom agent) needs to invoke a single NovelAI tool — picking a model, setting parameters, or generating/transforming an image interactively during an agent session. For shell scripting, batch jobs, or headless pipelines, use the novelai-cli skill instead; for multi-step recipes that orchestrate several tools, use the novelai-workflows skill.

Model selection
Model ids live in Model (nai/constants.py). Pick by quality need and
content domain:
Want best overall quality / natural language / multi-character?
→ nai-diffusion-5-full (V5, best quality, EN/JP natural language,
true alpha; vibes not yet supported)
→ nai-diffusion-5-curated (V5 curated, tighter aesthetics)
Solid all-rounder with vibes?
→ nai-diffusion-4-5-full (V4.5, default, supports character_prompts + vibes)
→ nai-diffusion-4-5-curated (V4.5 curated, tighter aesthetics, fewer Anlas)
Good quality, slightly faster, still V4 family?
→ nai-diffusion-4-full (V4)
→ nai-diffusion-4-curated-preview (V4 curated)
Pure anime, fastest, cheapest?
→ nai-diffusion-3 (V3 anime)
Furry content?
→ nai-diffusion-furry-3 (Furry v3)
Inpainting (any family)?
→ append "-inpainting" to the model id, e.g.
nai-diffusion-4-5-full-inpainting, nai-diffusion-3-inpainting,
nai-diffusion-furry-3-inpainting

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.
- 12d ago First seen · 368 lines · 56 tokens per session scan A e959be26c1bd
novelai-mcp-tools is a skill published in the GitHub repository xinvxueyuan/NovelAI-Image-MCP (4 stars, last pushed yesterday), licensed MIT. It adds 56 tokens to every session and 4,571 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
