The server exposes one tool, 'get_coordinates', with adequate but not excellent definition quality. The tool name follows verb-noun convention (get_*), and the input schema is properly structured with JSON Schema types, descriptions, and constraints. However, the tool lacks output schema documentation, critical error guidance, and tool annotations. The description is moderately detailed (111 chars) but could be more precise about when to use this tool vs. alternatives. Parameter descriptions are present and include ranges (limit: 1-10), which is good. No input validation guidance or recovery patterns are documented.

• Document the output schema formally. Example: 'Returns an object with: latitude (number), longitude (number), display_name (string), place_id (number), type (string), class (string), importance (number), bounding_box (object with south, north, west, east). If no results found, returns error object with suggestions array.'
• Enhance error responses to include recovery paths. When location not found, the response should say: 'No results for "X". Try: (1) search for a nearby city or region, (2) include country or state, (3) use a simpler place name. Available results API: call get_coordinates with broader search terms.'
• Add tool annotation for read-only status. In MCP spec (2026-07-28), register the tool with readOnlyHint: true so agents know the call is safe to retry.
• Document API reliability and timeout behavior. Add to tool description or as a note: 'Uses free OpenStreetMap Nominatim API. May have rate limits (~1 req/sec). Typical response time <500ms. If API is slow or unreachable, the tool returns a timeout error; the agent may retry after a delay.'
• Add dependency hint to description. Clarify: 'This tool is the opposite of reverse_geocode (if available). Use this when you have a place name and need coordinates. For bulk geocoding of many places, consider batch variants to reduce round-trips.'
• Validate the 'limit' parameter and provide clearer feedback. If limit is passed as 15 (exceeds max 10), return: 'Invalid limit: 15 exceeds maximum 10. Using limit=10.' This helps agents self-correct.
