Implementation Reference
- src/index.ts:415-439 (handler)The handler function for the 'list_tables' tool. It ensures a database connection, executes 'SHOW TABLES' query using the MySQL connection pool, logs the operation, and returns the list of tables as a formatted JSON string in the MCP response format.
private async handleListTables(requestId: string) { await this.ensureConnection(); try { console.error(`[${requestId}] Executing SHOW TABLES`); const [rows] = await this.pool!.query('SHOW TABLES'); console.error(`[${requestId}] SHOW TABLES completed, found ${Array.isArray(rows) ? rows.length : 0} tables`); return { content: [ { type: 'text', text: JSON.stringify(rows, null, 2), }, ], }; } catch (error) { const errorMsg = getErrorMessage(error); console.error(`[${requestId}] Failed to list tables: ${errorMsg}`); throw new McpError( ErrorCode.InternalError, `Failed to list tables: ${errorMsg}` ); } } - src/index.ts:236-249 (registration)Registration of the 'list_tables' tool in the ListToolsRequestSchema handler. Defines the tool name, description, and input schema (with no required parameters).
