Available components
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
- Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it. View diagnostics → Pass
- 0 of 31 dependencies flagged as unhealthy. View diagnostics → Pass
Provenance & Transparency10
- Repository check failed: the declared repository URL redirects; it must resolve directly. See how to fix → View diagnostics → Fail
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- License check failed: no license is declared. See how to fix → Fail
- Actively maintained (last published 53 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability78
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 326 tokens (~163/item across 2 items; 2 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 Management87
- Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 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

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 →
vdatum_convert ~297
Convert elevation values between vertical datums. Supports conversions between NAVD88, MLLW, MLW, MHW, MHHW, LMSL, xGEOID20b, IGLD85, and LWD using NOAA's coastalmodeling-vdatum. Points outside the datum conversion domain return inf. Args: datum_from: Source vertical datum (e.g. 'navd88', 'mllw'). datum_to: Target vertical datum (e.g. 'mllw', 'navd88'). lat: Latitude(s) as comma-separated values or single value (e.g. '30.0' or '30.0,26.0,27.5'). lon: Longitude(s) as comma-separated values or single value (e.g. '-80.0' or '-80.0,-75.0,-77.5'). z: Elevation(s) in meters as comma-separated values or single value (e.g. '1.5' or '1.5,0.0,0.1'). online: If true (default), fetch geotiff grids from AWS. Set false for offline/HPC use.
