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 | $0.00263 | $0.00263 |
| Opus 5.5 | $0.00105 | $0.00105 |
| Sonnet 5.5 | $0.00053 | $0.00053 |
| Haiku 4.5 | $0.00026 | $0.00026 |
Grade A, and why
n8n-mcp-server AGENTS.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 2mo 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.
What it actually says
Guidelines for Coding Agents
These rules apply to all automated contributors working on this project.
Development
- Use TypeScript and ES modules. Source files live under
src/. - Place tests in the
tests/directory mirroring the source structure. Test files must end with.test.ts. - Install dependencies with
npm installand build withnpm run buildwhen required. - Format code using
npm run lintand ensure all tests pass vianpm testbefore committing. - Do not commit files ignored by
.gitignore(e.g.node_modules/,build/,.env). - Follow existing patterns when adding new tools or resources as described in
docs/development.
Commit Messages
- Use short messages in the form
type: description(e.g.feat: add webhook tool,fix: handle null id).
Pull Requests
- Provide a concise summary of changes and reference related issues when opening a PR.
- CI must pass before requesting review.
Environment
- Node.js 20 or later is required.
Continuous Improvement
- After completing a task, review this guide and update it with any lessons learned about the codebase, coding principles, or user preferences.
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.
