Implementation Reference

• src/mcp_server_aws/server.py:333-339 (handler)

  Core handler implementation for the dynamodb_batch_execute tool, invoking boto3 DynamoDB client's batch_execute_statement with the provided statements and parameters.

  elif name == "dynamodb_batch_execute":
      response = dynamodb_client.batch_execute_statement(
          Statements=[{
              'Statement': statement,
              'Parameters': params
          } for statement, params in zip(arguments["statements"], arguments["parameters"])]
      )

• src/mcp_server_aws/tools.py:423-446 (schema)

  Schema definition for the dynamodb_batch_execute tool, specifying input requirements for statements and parameters.

  Tool(
      name="dynamodb_batch_execute",
      description="Execute multiple PartiQL statements in a batch",
      inputSchema={
          "type": "object",
          "properties": {
              "statements": {
                  "type": "array",
                  "description": "List of PartiQL statements to execute",
                  "items": {
                      "type": "string"
                  }
              },
              "parameters": {
                  "type": "array",
                  "description": "List of parameter lists for each statement",
                  "items": {
                      "type": "array"
                  }
              }
          },
          "required": ["statements", "parameters"]
      }
  ),

• src/mcp_server_aws/server.py:136-139 (registration)

  Tool registration via the MCP server's list_tools handler, which returns all AWS tools including dynamodb_batch_execute through get_aws_tools().

  async def list_tools() -> list[Tool]:
      """List available AWS tools"""
      logger.debug("Handling list_tools request")
      return get_aws_tools()
