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 | $0.02505 | $0.02505 |
| Opus 5.5 | $0.01002 | $0.01002 |
| Sonnet 5.5 | $0.00501 | $0.00501 |
| Haiku 4.5 | $0.00250 | $0.00250 |
Grade A, and why
simplenote-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 today.
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 — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.
simplenote-mcp-server
MCP server connecting Simplenote to Claude Desktop and other MCP clients. Python ≥3.10, package root simplenote_mcp/.
Commands
# Setup
pip install -e ".[dev,test,all]"
pre-commit install
# Tests — two independent trees, run separately (see tests/AGENTS.md and simplenote_mcp/tests/AGENTS.md for why)
make test-fast # SIMPLENOTE_OFFLINE_MODE=true .venv/bin/pytest tests/ -x -q --timeout=30
make test-legacy # SIMPLENOTE_OFFLINE_MODE=true .venv/bin/pytest simplenote_mcp/tests/ -q --timeout=30 --no-cov
make test # both, via .venv/bin/pytest -q (root testpaths = tests/ only; legacy run separately in CI)
# Quality
ruff check .
ruff format .
mypy simplenote_mcp
bandit -c pyproject.toml -r simplenote_mcp # always pass -c; bare invocation misapplies exclude_dirs
# Evaluations (npm devDependency tree, never shipped — see package.json)
npm install && npm run eval:smoke # eval:basic, eval:comprehensive, eval:all also available
Always invoke .venv/bin/pytest / .venv/bin/ruff / .venv/bin/mypy / .venv/bin/bandit explicitly, or prefix with source .venv/bin/activate && in the same shell call — each Bash invocation is a fresh shell, so a prior activate does not persist and bare commands silently resolve through the pyenv shim to the global environment instead of .venv.

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.

simplenote-mcp-server AGENTS.md is an instructions file published in the GitHub repository docdyhr/simplenote-mcp-server (21 stars, last pushed today), licensed MIT. It adds 2,505 tokens to every session, about $0.0100 per session on Opus 5.5. 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 2026-08-30.
