Implementation Reference
- src/index.ts:610-661 (handler)The main handler function that executes the 'check_version' tool: validates input, fetches EOL cycle data from endoflife.date API for the given product/version, caches the query, and returns the relevant cycle information as JSON.
private async handleCheckVersion(args: CheckVersionArgs) { const { product, version } = args; // Validate product exists if (!this.availableProducts.includes(product)) { return { content: [{ type: "text", text: `Invalid product: ${product}. Use list_products tool to see available products.` }], isError: true }; } try { const response = await this.axiosInstance.get(`/${product}.json`); const cycles = response.data as EOLCycle[]; const filteredCycles = version ? cycles.filter(cycle => cycle.cycle.startsWith(version)) : cycles; this.recentQueries.unshift({ product, version, response: filteredCycles, timestamp: new Date().toISOString() }); if (this.recentQueries.length > API_CONFIG.MAX_CACHED_QUERIES) { this.recentQueries.pop(); } return { content: [{ type: "text", text: JSON.stringify(filteredCycles, null, 2) }] }; } catch (error) { if (axios.isAxiosError(error)) { return { content: [{ type: "text", text: `EOL API error: ${error.response?.data?.message ?? error.message}` }], isError: true }; } throw error; } } - src/types.ts:19-37 (schema)TypeScript interface defining the input arguments for 'check_version' tool and the type guard function to validate them.
export interface CheckVersionArgs { product: string; version?: string; } export interface ListProductsArgs { filter?: string; } // Type guards export function isValidCheckVersionArgs(args: any): args is CheckVersionArgs { return ( typeof args === "object" && args !== null && "product" in args && typeof args.product === "string" && (args.version === undefined || typeof args.version === "string") ); } - src/index.ts:285-302 (registration)Registration of the 'check_version' tool in the ListToolsRequestSchema handler, including name, description, and JSON schema matching CheckVersionArgs.
