Common questions
Is GridPin offline geocoder safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed today, and the latest version (0.5.0) reached the registry 6 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

gridpin-mcp — offline geocoding for AI agents
An MCP server that lets an agent geocode addresses with GridPin: one memory-mapped file per country, read on your machine. No API key, no rate limit, and no query leaves the machine. The only network step is downloading a country sheet once, verified against the signed GridPin release.
Countries (release v0.7.1): United States, Canada, Germany, France, Italy, Spain, Mexico, Netherlands, Brazil, Serbia.
Add it to an agent
Claude Code:
$ claude mcp add gridpin -- uvx gridpin-mcpAny client that reads an mcpServers config (Claude Desktop, Cursor, ...):
{ "mcpServers": { "gridpin": { "command": "uvx", "args": ["gridpin-mcp"] } } }To keep sheets in another directory, pass GRIDPIN_HOME in the server's own environment:
{ "mcpServers": { "gridpin": { "command": "uvx", "args": ["gridpin-mcp"],"env": { "GRIDPIN_HOME": "/path/to/sheets" } } } }
Exporting it in your shell is not enough. Some MCP clients start the server with only a few environment variables (clients built on the MCP Python SDK pass HOME, LOGNAME, PATH, SHELL, TERM and USER on macOS and Linux), so GRIDPIN_HOME and XDG_CACHE_HOME from your shell never reach it and sheets go to ~/.cache/gridpin.
download_sheet fetches a whole sheet in one tool call, and the larger sheets can take longer than a client allows for one call (mcp-haystack's MCPToolset, for example, stops after 30 s by default). Raise the client's tool timeout, or download the sheet beforehand in a terminal, with the same GRIDPIN_HOME as the server; the tool then returns at once:
$ uvx --from gridpin-mcp gridpin-fetch frStep-by-step setup for agents (requirements, settings, verification): llms-install.md.
If GridPin is useful to you, a star on GitHub helps other people find it.
Tools
| Tool | What it does |
|---|---|
list_countries | covered countries, sheet sizes, which are downloaded |
download_sheet | fetch one country sheet (32-677 MB) once, verify its SHA-256; the only tool that uses the network |
geocode | address text -> ranked candidates with lat, lon, precision, confidence |
reverse | coordinates -> nearest indexed addresses with distance_m |
batch | up to 1000 addresses of one country per call, in input order |
Results are the same as the GridPin CLI, Python and DuckDB return. Treat street or city precision as approximate.
Download a sheet without MCP
$ pip install gridpin-mcp$ gridpin-fetch fr # prints the path, e.g. ~/.cache/gridpin/v0.5.0/france.bin
import gridpinfrom gridpin_mcp import sheets
path = sheets.download("fr") # no-op when already downloaded gridpin.Geocoder(str(path)).geocode("1 rue de la Paix, Paris", 1)
Sheets go to $GRIDPIN_HOME, else $XDG_CACHE_HOME/gridpin, else ~/.cache/gridpin. Sizes and SHA-256 of every sheet are pinned in the package from the signed release attestation; a download that does not match is discarded.
