Implementation Reference
- src/index.ts:234-248 (handler)The handler function for the 'get_nearby_notable_observations' tool. It constructs parameters from input args, calls the shared makeRequest function to fetch notable observations near the given lat/lng from the eBird API, and returns the JSON-formatted result.async (args) => { const params: Record<string, string | number | boolean> = { lat: args.lat, lng: args.lng, back: args.back, detail: args.detail, dist: args.dist, hotspot: args.hotspot, sppLocale: args.spp_locale, }; if (args.max_results) params.maxResults = args.max_results; const result = await makeRequest("/data/obs/geo/recent/notable", params); return { content: [{ type: "text", text: JSON.stringify(result, null, 2) }] }; }
- src/index.ts:224-233 (schema)Zod schema defining the input parameters for the tool, including required lat/lng, optional back days, detail level, distance radius, hotspot filter, max results, and species locale.{ lat: z.number().min(-90).max(90).describe("Latitude"), lng: z.number().min(-180).max(180).describe("Longitude"), back: z.number().min(1).max(30).default(14).describe("Number of days back to fetch"), detail: z.enum(["simple", "full"]).default("simple").describe("Level of detail"), dist: z.number().min(0).max(50).default(25).describe("Search radius in kilometers"), hotspot: z.boolean().default(false).describe("Only fetch from hotspots"), max_results: z.number().min(1).max(10000).optional().describe("Maximum observations to return"), spp_locale: z.string().default("en").describe("Language for common names"), },
- src/index.ts:221-249 (registration)Registration of the 'get_nearby_notable_observations' tool using McpServer.tool(), including name, description, input schema, and inline handler function.server.tool( "get_nearby_notable_observations", "Get notable/rare observations near a location.", { lat: z.number().min(-90).max(90).describe("Latitude"), lng: z.number().min(-180).max(180).describe("Longitude"), back: z.number().min(1).max(30).default(14).describe("Number of days back to fetch"), detail: z.enum(["simple", "full"]).default("simple").describe("Level of detail"), dist: z.number().min(0).max(50).default(25).describe("Search radius in kilometers"), hotspot: z.boolean().default(false).describe("Only fetch from hotspots"), max_results: z.number().min(1).max(10000).optional().describe("Maximum observations to return"), spp_locale: z.string().default("en").describe("Language for common names"), }, async (args) => { const params: Record<string, string | number | boolean> = { lat: args.lat, lng: args.lng, back: args.back, detail: args.detail, dist: args.dist, hotspot: args.hotspot, sppLocale: args.spp_locale, }; if (args.max_results) params.maxResults = args.max_results; const result = await makeRequest("/data/obs/geo/recent/notable", params); return { content: [{ type: "text", text: JSON.stringify(result, null, 2) }] }; } );
- src/index.ts:19-36 (helper)Shared utility function used by all tools, including this one, to construct and make authenticated GET requests to the eBird API endpoints.async function makeRequest(endpoint: string, params: Record<string, string | number | boolean> = {}): Promise<unknown> { const url = new URL(`${BASE_URL}${endpoint}`); Object.entries(params).forEach(([key, value]) => { if (value !== undefined && value !== null) { url.searchParams.append(key, String(value)); } }); const response = await fetch(url.toString(), { headers: { "X-eBirdApiToken": API_KEY! }, }); if (!response.ok) { throw new Error(`eBird API error: ${response.status} ${response.statusText}`); } return response.json(); }
