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 | $0.00388 | $0.00388 |
| Opus 5 | $0.00194 | $0.00194 |
| Sonnet 5 | $0.00078 | $0.00078 |
| Haiku 4.5 | $0.00039 | $0.00039 |
Grade A, and why
e-stats-mcp 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 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.
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
AGENTS.md
Guidance for Codex and other coding agents working in this repository.
Project
This repository implements an MCP server for the e-Stat API using Python, FastMCP, httpx, and Typer. Keep tool return values JSON-serializable unless a tool explicitly returns CSV text.
Commands
Run these before handing off changes:
uv run pytest -q
uv run ruff check .
uv run mypy e_stats_mcp
Use uv run ruff format ... for formatting touched Python files.
API Notes
- Live e-Stat API calls require
E_STAT_APP_ID; do not commit real app IDs. - Prefer the official e-Stat API 3.0 manual and sample forms when checking endpoint names, parameter casing, and response shapes.
- e-Stat parameter names are case-sensitive in practice. Preserve camelCase
names such as
dataSetId,startPosition, andstatsDataId. refDatasetdoes not expose API-sidelimit/startPositionfor dataset list paging.get_datasetapplies list paging inside the MCP server.getDataCataloghas no CSV endpoint in e-Stat API 3.0.get_data_catalog_csvfetches JSON and convertsDATA_CATALOG_INFrecords to CSV locally.- Broad
getDataCatalogsearches can be slow even with a smalllimit. Preferget_stats_listfirst, then retryget_data_catalogwithstats_codeor another narrowing parameter. Keep recovery hints machine-readable.
Testing
Unit tests should mock HTTP with DummyClient and set E_STAT_APP_ID via
monkeypatch. Avoid tests that require a real e-Stat application ID unless they
are explicitly marked or documented as integration tests.
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.

e-stats-mcp AGENTS.md is an instructions file published in the GitHub repository koizumikento/e-stats-mcp (0 stars, last pushed 4d ago), licensed MIT. It adds 388 tokens to every session, about $0.0019 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.
