Common questions about connecting and running Ground.
What kind of reference data does this server provide?
The Ground MCP server offers classification systems (like ISO standards), real-time world data (exchange rates, geographic info), and unit conversion utilities. Exact datasets available depend on the API's current offerings—check the hosted endpoint documentation for the full catalog.
How do I authenticate with the Ground reference data API?
The server connects via HTTP to https://mcp.ground.fyi/mcp. Authentication requirements (API keys, headers, etc.) are determined by Ground's endpoint configuration. Consult Ground's documentation or contact their support for credential setup.
Is there a cost to use this MCP server?
Pricing is not specified in the server metadata. Visit fyi.ground or contact Ground directly to learn about free tiers, rate limits, and paid plans.
Can I use this for real-time data like stock prices or weather?
The server advertises 'real-time world data,' but the specific datasets available are not detailed in the registry. Unit conversions and classification lookups are confirmed; for real-time feeds, verify Ground's current API offerings.
What happens if the Ground API is unavailable?
Since this is an HTTP-based remote server, your MCP client will receive an error if https://mcp.ground.fyi/mcp is down or unreachable. Implement retry logic and fallback data sources in your application for production use.
