Implementation Reference

• src/executor.ts:578-610 (handler)

  The handler function that implements the core logic of the 'api_put' tool by performing a PUT request using the API client.

  async function handleApiPut(client: APIRequestContext, args: any): Promise<{ toolResult: CallToolResult }> {
    try {
      const options = {
        data: args.data,
        headers: args.headers || { 'Content-Type': 'application/json' }
      };
  
      const response = await client.put(args.url, options);
      const responseData = await getResponseData(response);
  
      return {
        toolResult: {
          content: [
            {
              type: "text",
              text: `PUT ${args.url} - Status: ${response.status()}`,
            },
            ...responseData
          ],
          isError: false,
        },
      };
    } catch (error) {
      return {
        toolResult: {
          content: [{
            type: "text",
            text: `PUT request failed: ${(error as Error).message}`,
          }],
          isError: true,
        },
      };
    }

• src/tools.ts:164-179 (schema)

  The tool schema definition including name, description, and input validation schema for 'api_put'.

  {
    name: "api_put",
    description: "Perform a PUT request to an API endpoint",
    inputSchema: {
      type: "object",
      properties: {
        url: { type: "string", description: "API endpoint URL" },
        data: { type: "string", description: "Request body data (JSON string)" },
        headers: { 
          type: "object", 
          description: "Request headers",
          additionalProperties: { type: "string" }
        }
      },
      required: ["url", "data"]
    }

• src/executor.ts:215-216 (registration)

  The dispatch/registration case in the main executeTool function that maps the 'api_put' tool name to its handler.

  case "api_put":
    return await handleApiPut(apiClient!, args);
