search_law日本の法令をキーワード・略称・分野で検索する。e-Gov法令API v2 を使用。略称辞書による正式名称への自動補完あり。
get_law日本の法令から条文を取得する。略称（消法・所法・労基法 等）対応。条/項/号レベル指定可能。
get_toc法令の目次（編・章・節・条の構造）のみを取得する。トークン節約用。depth で階層を浅く打ち切れる（民法・会社法のような大規模法令の概観把握向け）。
search_fulltext法令本文をキーワードで横断全文検索する。HOUKI_HUB_BULK_CACHE=1 環境時に SQLite FTS5 で動作。未有効時は API フォールバック。
resolve_abbreviation略称・通称から正式な法令名と law_id を解決する。略称辞書の内容を確認するための診断ツール。
get_law_revisions法令の改正履歴を取得する。e-Gov v2 /law_revisions を使用。各改正の公布日・施行日・改正法令番号・状態（現行/旧法/未施行）等を返す。
explain_law_type法令種別（憲法・法律・政令・省令・規則・条例・告示・通達 等）の制定主体・階層上の位置・国民への拘束力・実務上の注意点を解説する。法務専門家でない利用者が「政令と省令の違い」「通達は守らなくていいのか」等を確認するための知識ツール。
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
fast-xml-parser has an entity encoding bypass via regex injection in DOCTYPE entity names
When Vitest UI server is listening, arbitrary file can be read and executed
Vitest allows Remote Code Execution when accessing a malicious website while Vitest API server is listening
fast-xml-parser affected by numeric entity expansion bypassing all entity expansion limits (incomplete fix for CVE-2026-26278)
fast-xml-parser affected by DoS through entity expansion in DOCTYPE (no expansion limit)
HOUKI_EGOV_BULK_RETRYHOUKI_EGOV_CONCURRENCYHOUKI_EGOV_DB_PATHDB のデフォルト配置は ${XDG_CACHE_HOME:-~/.cache}/houki-egov-mcp/laws.db（ で変更可）。HOUKI_EGOV_INCREMENTAL_LIMIT_DAYSHOUKI_HUB_BULK_CACHEHOUKI_HUB_EXTENSIONSXDG_CACHE_HOMEDB のデフォルト配置は ${:-~/.cache}/houki-egov-mcp/laws.db（HOUKI_EGOV_DB_PATH で変更可）。Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
7/7 tools missing one or more hints — search_law (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_law (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_toc (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Shell command execution
5 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
1 critical, 2 high severity in production deps — fast-xml-parser@4.5.0 (critical), fast-xml-parser@4.5.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
