Implementation Reference
- src/index.ts:311-361 (handler)The primary handler function for the 'insert_data' tool. It validates the input arguments, checks that the SQL query starts with 'INSERT INTO', executes the query using the MySQL connection pool, logs the transaction, and returns a success response with the query result or an error message.private async handleInsertData(request: any, transactionId: string) { if (!isValidSqlQueryArgs(request.params.arguments)) { throw new McpError( ErrorCode.InvalidParams, 'Invalid SQL query arguments.' ); } const query = request.params.arguments.query; if (!isInsertQuery(query)) { throw new McpError( ErrorCode.InvalidParams, 'Only INSERT INTO queries are allowed with insert_data tool.' ); } console.error(`[${transactionId}] Executing INSERT query: ${query}`); try { const [result] = await this.pool.query(query); console.error(`[${transactionId}] Data inserted successfully`); return { content: [ { type: 'text', text: JSON.stringify({ success: true, message: 'Data inserted successfully', result }, null, 2), }, ], }; } catch (error) { console.error(`[${transactionId}] Query error:`, error); if (error instanceof Error) { return { content: [ { type: 'text', text: `MySQL error: ${error.message}`, }, ], isError: true, }; } throw error; } }
- src/index.ts:125-134 (schema)Input schema definition for the 'insert_data' tool, specifying an object with a required 'query' property of type string for the INSERT SQL statement.inputSchema: { type: 'object', properties: { query: { type: 'string', description: 'The SQL INSERT INTO query to execute.', }, }, required: ['query'], },
- src/index.ts:122-135 (registration)Registration of the 'insert_data' tool in the tools list returned by ListToolsRequestSchema handler, including name, description, and input schema.{ name: 'insert_data', description: 'Inserts data into a table in the MySQL database.', inputSchema: { type: 'object', properties: { query: { type: 'string', description: 'The SQL INSERT INTO query to execute.', }, }, required: ['query'], }, },
- src/index.ts:191-192 (registration)Dispatch registration in the CallToolRequestSchema switch statement that routes calls to 'insert_data' to the handleInsertData method.case 'insert_data': return this.handleInsertData(request, transactionId);
- src/index.ts:37-39 (helper)Helper function used by the handler to validate that the provided query is an INSERT INTO statement.// Check if query is for inserting data const isInsertQuery = (query: string): boolean => query.trim().toLowerCase().startsWith('insert into');
