Implementation Reference
- src/index.ts:271-315 (handler)Implements the core logic of the 'search_all' tool by searching multiple platforms (Stack Overflow, MDN, GitHub, npm, PyPI) concurrently, caching results, and formatting the output.
private async searchAll(query: string, limit: number = 3): Promise<string> { const cacheKey = `all:${query}:${limit}`; const cached = cache.get<string>(cacheKey); if (cached) return cached; try { // Execute non-GitHub searches first const [so, mdn, npm, pypi] = await Promise.all([ this.searchStackOverflow(query, limit).catch(error => `Error: ${error instanceof Error ? error.message : 'Unknown error'}` ), this.searchMDN(query).catch(error => `Error: ${error instanceof Error ? error.message : 'Unknown error'}` ), this.searchNpm(query, limit).catch(error => `Error: ${error instanceof Error ? error.message : 'Unknown error'}` ), this.searchPyPI(query).catch(error => `Error: ${error instanceof Error ? error.message : 'Unknown error'}` ) ]); let results = `=== Stack Overflow Results ===\n${so}\n\n` + `=== MDN Documentation ===\n${mdn}\n\n`; // Try GitHub search separately try { const gh = await this.searchGitHub(query, undefined, limit); results += `=== GitHub Results ===\n${gh}\n\n`; } catch (error) { results += `=== GitHub Results ===\nGitHub search currently unavailable\n\n`; } results += `=== npm Packages ===\n${npm}\n\n` + `=== PyPI Packages ===\n${pypi}`; cache.set(cacheKey, results); return results; } catch (error) { throw new McpError( ErrorCode.InternalError, `Search all platforms error: ${error instanceof Error ? error.message : 'Unknown error'}` ); } } - src/index.ts:415-430 (schema)Defines the input schema for the 'search_all' tool, including required 'query' string and optional 'limit' number with constraints.
