Provides forward geocoding using the OpenStreetMap Nominatim API, converting location queries into coordinates and address details.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@geocoding-mcp geocode the Eiffel Tower"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

Scored across 1 tool
With only a single tool there is no possibility of overlap or misselection; 'geocode' has one unmistakable purpose (forward geocoding a query string).
The lone tool name 'geocode' is clear, lowercase, and well-chosen, but with just one tool there is no verb_noun pattern to demonstrate consistency across the set.
One tool is thin for a service whose domain (Nominatim) naturally includes forward and reverse geocoding plus lookup variants; the surface feels under-built rather than well-scoped.
Forward geocoding is covered, but obvious companion operations such as reverse geocoding (coordinates to address) and batch/multi-result lookup are absent, leaving notable gaps in the geocoding lifecycle.
