How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-kokkai-diet). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 2 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability61
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1038 tokens (~346/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_speech ~96
Fetch one Diet speech's full text and metadata by its speechID (from search_speeches' "speech_id" field). Returns the complete speech text (search_speeches only gives a preview), speaker, party, house, meeting, date, session, and permalink.
| Name | Type | Req | Description |
|---|---|---|---|
| speech_id | string | yes | A speechID from search_speeches, e.g. "122105261X01720260727_012". |
No output schema declared.
No examples provided.
search_meetings ~408
Search Japanese National Diet meetings/sittings (a meeting = one committee or plenary session on one day) by meeting name, chamber, or date range, via kokkai.ndl.go.jp. Requires at least one of "query", "meeting_name", or "house". Returns each meeting's issueID (for fetching its speeches with search_speeches or get_speech), house, meeting name, session number, issue number, date, and permalink. Queries are Japanese-first: kokkai.ndl.go.jp indexes speeches in Japanese, so Japanese keywords match; English keywords (e.g. "semiconductors" instead of "半導体") will under-match or return zero even when Japanese-language debate on the topic exists. PAGINATION: this endpoint caps results at 10 per request (default 3) — lower than search_speeches. Check "next_start_record"; a null value means this page is the end of the result set, anything else means more meetings exist.
| Name | Type | Req | Description |
|---|---|---|---|
| from | string | – | Earliest meeting date, inclusive, YYYY-MM-DD. |
| house | string | – | Chamber: "衆議院", "参議院", "両院", or "両院協議会". |
| max_records | number | – | Results per request, 1-10 (default 3). The API rejects values outside this range — this cap is lower than search_speeches'. |
| meeting_name | string | – | Meeting/committee name in Japanese, partial match, e.g. "予算委員会" (Budget Committee), "本会議" (plenary). |
| query | string | – | Japanese keyword(s) matched against speech text within the meeting, partial match. |
| start_record | number | – | 1-based offset for pagination (default 1). Use the previous response's "next_start_record" to fetch the next page. |
| until | string | – | Latest meeting date, inclusive, YYYY-MM-DD. |
No output schema declared.
No examples provided.
search_speeches ~477
Full-text search of Japanese National Diet (parliament) speeches back to 1947, via the National Diet Library's kokkai.ndl.go.jp API. Requires "query" and/or "speaker". Returns speaker, party (speaker_group), house, meeting, date, session, and a permalink for each hit — the actual speech text is a short preview here; fetch the full text with get_speech(speech_id). Queries are Japanese-first: kokkai.ndl.go.jp indexes speeches in Japanese, so Japanese keywords match; English keywords (e.g. "semiconductors" instead of "半導体") will under-match or return zero even when Japanese-language debate on the topic exists. PAGINATION: the API caps results at 100 per request (default 30) — check "next_start_record" in the response; if it is not null, more speeches exist beyond this page and were NOT returned. Never treat a page as the complete result set without checking it.
| Name | Type | Req | Description |
|---|---|---|---|
| from | string | – | Earliest speech date, inclusive, YYYY-MM-DD. |
| house | string | – | Chamber: "衆議院" (House of Representatives), "参議院" (House of Councillors), "両院" (joint), or "両院協議会" (joint committee). |
| max_records | number | – | Results per request, 1-100 (default 30). The API rejects values outside this range. |
| query | string | – | Japanese keyword(s), space-separated for AND search, partial match. E.g. "半導体" (semiconductors), "少子化 対策" (declining birthrate AND countermeasures). English keywords under-match — prefer Japanese. |
| speaker | string | – | Speaker name in Japanese, partial match, e.g. "岸田文雄". OR-matched if it has multiple readings. |
| speaker_group | string | – | Political party / parliamentary group (会派) in Japanese, partial match, e.g. "立憲民主党". |
| start_record | number | – | 1-based offset for pagination (default 1). Use the previous response's "next_start_record" to fetch the next page. |
| until | string | – | Latest speech date, inclusive, YYYY-MM-DD. |
