Transform coordinate systems and map projections using EPSG, WKT, and Proj formats.
This tool is described as a local MCP server for coordinate transformations and map projections, with no declared secrets or remote endpoints; combined with its open-source MIT license, the overall risk appears relatively low. However, it is objectively marked as executing code, and adoption/maintenance signals are limited, so basic isolation and source review are still advisable.
The materials explicitly state that no secrets or environment variables are required, and there is no described collection, storage, or transmission of credentials, so credential abuse exposure appears low.
The materials declare no remote endpoints, and the description is limited to coordinate transformation/projection functions, with no factual indication of user data being sent to external services.
The objective checks mark this tool as executes-code, meaning it runs code/processes locally; this is a normal capability for this class of tool, but it should still be run with least privilege and a limited host exposure surface.
The description does not clearly define its file read/write scope; as a local MCP service, it would typically at least handle input coordinates, projection definitions, or related local resources. There is no evidence of overbroad access beyond its stated purpose, but the data access boundary is not clearly documented.
Positive signals include being open source under an MIT license, allowing source review; however, it comes from a third-party registry, the GitHub repo has 0 stars, and maintenance status is unknown, so community validation and maintenance signals are weak. Supply-chain confidence is therefore limited, but there are no explicit red flags.

Convert these coordinates from EPSG:4326 to EPSG:3857 and return the transformed values with a brief CRS explanation: [(116.397,39.908),(121.4737,31.2304)].
Returns transformed coordinates for each point and explains the source and target coordinate reference systems.
Parse the following WKT coordinate system definition, identify the corresponding EPSG code, and output it as a Proj string.
Provides a structured WKT interpretation, likely EPSG code, and the corresponding Proj expression.
