The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
wkt_to_geojsonConvert Well-Known Text (WKT) to GeoJSON format
geojson_to_wktConvert GeoJSON to Well-Known Text (WKT) format
csv_to_geojsonConvert CSV with geographic data to GeoJSON
geojson_to_csvConvert GeoJSON to CSV format
geojson_to_topojsonConvert GeoJSON to TopoJSON format (more compact with shared boundaries)
topojson_to_geojsonConvert TopoJSON to GeoJSON format
kml_to_geojsonConvert KML to GeoJSON format
geojson_to_kmlConvert GeoJSON to KML format
coordinates_to_locationConvert latitude/longitude coordinates to location name using reverse geocoding
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
xmldom allows multiple root nodes in a DOM
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
xmldom: DocType `name` Injection Bypasses requireWellFormed
xmldom: Uncontrolled recursion in XML serialization leads to DoS
xmldom: Attribute name injection via setAttribute() bypasses requireWellFormed
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
9/9 tools missing one or more hints — wkt_to_geojson (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); geojson_to_wkt (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); csv_to_geojson (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 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.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
1 critical, 13 high severity in production deps — xmldom@0.6.0 (critical), @modelcontextprotocol/sdk@0.6.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
5/9 production deps abandoned (no release in 2+ years): topojson-client@2022-06-27 (4.2y), topojson-server@2022-06-27 (4.2y), tokml@2022-09-20 (4y)
