Implementation Reference

• src/index.ts:2277-2283 (handler)

  The core handler logic for the 'list_ssm_parameters' tool. It sends a DescribeParametersCommand to the SSMClient, extracts parameter names, types, and descriptions, and returns them as JSON.
  if (name === "list_ssm_parameters") { // DescribeParameters mainly lists them const command = new DescribeParametersCommand({}); const response = await ssmClient.send(command); const params = response.Parameters?.map(p => ({ Name: p.Name, Type: p.Type, Description: p.Description })) || []; return { content: [{ type: "text", text: JSON.stringify(params, null, 2) }] }; }
• src/index.ts:762-766 (registration)

  Tool registration in the ListToolsRequestSchema handler, including name, description, and input schema (empty object).
  { name: "list_ssm_parameters", description: "Lists SSM Parameters (names only).", inputSchema: { "type": "object", "properties": {} } },
• src/index.ts:76-76 (helper)

  Initialization of the SSMClient used by the list_ssm_parameters handler.
  const ssmClient = new SSMClient({});
• src/index.ts:43-43 (helper)

  Import of SSMClient and DescribeParametersCommand required for the tool implementation.
  import { SSMClient, DescribeParametersCommand } from "@aws-sdk/client-ssm";
