## What it does

The server exposes `geocode_address` to turn a place or address into coordinates, then `compute_route` to calculate a route between coordinates. Route requests can include waypoints and preferences such as avoiding stairs, tolls, or unpaved roads. Have a place name but no coordinates? Geocode it first.

Each tool returns a readable summary alongside JSON, plus an attribution string that should appear with any result you display. Coverage spans Europe. You need an `OVO_API_KEY` to use the service, and geocoding searches and routing requests draw on separate allowances. Both tools are read-only.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `OVO_API_KEY`, `OVO_API_URL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

## When to use it
- look up coordinates for a station or address
- calculate a bike route between two places
- compare route options by road and surface details
- plan a walking or wheelchair route

## Example prompts
- Find coordinates for Gare de Rennes, then plan a safe bike trip to Thabor park.
- Route between these coordinates for a wheelchair and avoid steps.
- Compare scooter routes and include cycle-lane share and turn instructions.
