- **Supply Chain Security**: 50/100
  - Malware scan not yet available for this package.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it.
  - 1 of 29 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 100/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to gridpin/gridpin).

## Common questions

### What is the GridPin offline geocoder MCP server?

GridPin offline geocoder is an MCP server listed in the public MCP registry as io.github.gridpin/gridpin-mcp. Offline geocoding and reverse geocoding from one local file per country. No API key, no rate limit. This page covers its PyPI package (gridpin-mcp).

### Is the GridPin offline geocoder MCP server safe to use?

GridPin offline geocoder scores 72 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the GridPin offline geocoder MCP server expose?

GridPin offline geocoder exposes 5 tools: list_countries, download_sheet, geocode, reverse, batch. Their descriptions and schemas cost roughly 291 tokens of context every time the server is loaded.

### Is the GridPin offline geocoder MCP server still maintained?

GridPin offline geocoder is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the GridPin offline geocoder MCP server under?

GridPin offline geocoder declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
