Implementation Reference
- src/tools/webSearch.ts:15-103 (handler)Async handler that performs the web search using Exa API: logs the request, sends POST with query and config, processes results as JSON, handles axios and generic errors with appropriate responses.
handler: async ({ query, numResults }, extra) => { const requestId = `web_search_exa-${Date.now()}-${Math.random().toString(36).substring(2, 7)}`; const logger = createRequestLogger(requestId, 'web_search_exa'); logger.start(query); try { // Create a fresh axios instance for each request const axiosInstance = axios.create({ baseURL: API_CONFIG.BASE_URL, headers: { 'accept': 'application/json', 'content-type': 'application/json', 'x-api-key': process.env.EXA_API_KEY || '' }, timeout: 25000 }); const searchRequest: ExaSearchRequest = { query, type: "auto", numResults: numResults || API_CONFIG.DEFAULT_NUM_RESULTS, contents: { text: { maxCharacters: API_CONFIG.DEFAULT_MAX_CHARACTERS }, livecrawl: 'always' } }; logger.log("Sending request to Exa API"); const response = await axiosInstance.post<ExaSearchResponse>( API_CONFIG.ENDPOINTS.SEARCH, searchRequest, { timeout: 25000 } ); logger.log("Received response from Exa API"); if (!response.data || !response.data.results) { logger.log("Warning: Empty or invalid response from Exa API"); return { content: [{ type: "text" as const, text: "No search results found.

schema: { query: z.string().describe("Search query"), numResults: z.number().optional().describe("Number of search results to return (default: 5)") }, - src/tools/webSearch.ts:8-105 (registration)Registers the 'web_search_exa' tool in the toolRegistry with name, description, schema, handler function, and enabled flag.
