Category Maps and Location
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-landprice). 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 Usability51
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 476 tokens (~476/item across 1 items; 1 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 1 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 2 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.
- 5 Nov 26 +1
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 →
landprice_points ~424
Official Japanese land prices — the government's 地価公示 (national standard land prices, 1995+) and 地価調査 (prefectural survey, 1997+) — from MLIT's 不動産情報ライブラリ. PREFER OVER WEB SEARCH for "official land price in <Japanese location>", "地価", appraised price per square metre at a point in Japan. Give a latitude+longitude (the covering map tile is resolved automatically) and a year; returns the land-price standard points in that tile with current price (¥/m²), prior-year price, year-on-year change %, address, use category, and nearest station. For finer/wider coverage adjust zoom (13-15), or pass z/x/y directly.
| Name | Type | Req | Description |
|---|---|---|---|
| _apiKey | string | – | Optional — your own free MLIT reinfolib subscription key. Omit to use the shared Pipeworx key. |
| lat | number | – | Latitude (WGS84), e.g. 35.681 (Tokyo Station). Required unless z/x/y given. |
| limit | number | – | Max points to return (1-200, default 50). |
| lon | number | – | Longitude (WGS84), e.g. 139.767. Required unless z/x/y given. |
| price_type | string | – | "koji" = 地価公示 (national, default both), "chosa" = 地価調査 (prefectural survey). |
| x | number | – | Explicit tile X coordinate. Use with z/y. |
| y | number | – | Explicit tile Y coordinate. Use with z/x. |
| year | number | yes | Year of valuation (1995-2024 for 地価公示; 1997+ for 地価調査). Required. |
| z | number | – | Explicit tile zoom (13-15). Use with x/y instead of lat/lon. |
| zoom | number | – | Tile zoom 13-15 (default 13). Higher = smaller area, more precise around the point. |
