Implementation Reference

• src/mcp_server_aws/server.py:212-219 (handler)

  The core handler logic for the 'dynamodb_update_ttl' tool, which invokes the AWS DynamoDB client's update_time_to_live method with the provided table name, TTL enabled status, and attribute.

  elif name == "dynamodb_update_ttl":
      response = dynamodb_client.update_time_to_live(
          TableName=arguments["table_name"],
          TimeToLiveSpecification={
              'Enabled': arguments["ttl_enabled"],
              'AttributeName': arguments["ttl_attribute"]
          }
      )

• src/mcp_server_aws/tools.py:401-422 (schema)

  Input schema and Tool definition for 'dynamodb_update_ttl', specifying parameters: table_name (string), ttl_enabled (boolean), ttl_attribute (string).

  Tool(
      name="dynamodb_update_ttl",
      description="Update the TTL settings for a table",
      inputSchema={
          "type": "object",
          "properties": {
              "table_name": {
                  "type": "string",
                  "description": "Name of the DynamoDB table"
              },
              "ttl_enabled": {
                  "type": "boolean",
                  "description": "Whether TTL should be enabled"
              },
              "ttl_attribute": {
                  "type": "string",
                  "description": "The attribute name to use for TTL"
              }
          },
          "required": ["table_name", "ttl_enabled", "ttl_attribute"]
      }
  ),

• src/mcp_server_aws/server.py:136-140 (registration)

  Tool registration via the MCP list_tools handler, which returns get_aws_tools() containing the 'dynamodb_update_ttl' Tool object.

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