Implementation Reference

• src/index.ts:171-174 (handler)

  The handler function that executes the delete_monitor tool. It accepts an id parameter and makes a DELETE request to the /monitors/{id} API endpoint, returning the response as JSON.

  async ({ id }) => {
    const data = await apiRequest(`/monitors/${id}`, { method: "DELETE" });
    return { content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }] };
  }

• src/index.ts:159-175 (registration)

  The complete registration of the delete_monitor tool with the MCP server, including the tool name, description, schema, hints (destructive), and the handler function.

  server.tool(
    "delete_monitor",
    "Permanently delete a monitor and all its check history. This cannot be undone.",
    {
      id: z.string().describe("Monitor ID"),
    },
    {
  
        readOnlyHint: false,
        destructiveHint: true,
        openWorldHint: false,
    },
    async ({ id }) => {
      const data = await apiRequest(`/monitors/${id}`, { method: "DELETE" });
      return { content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }] };
    }
  );

• src/index.ts:162-164 (schema)

  Zod schema defining the input validation for delete_monitor tool. It requires a single parameter 'id' as a string representing the Monitor ID.

  {
    id: z.string().describe("Monitor ID"),
  },

• src/index.ts:20-42 (helper)

  The apiRequest helper function used by delete_monitor handler to make authenticated HTTP requests to the CronAlert API. It handles API key retrieval, request headers, error handling, and JSON response parsing.

  async function apiRequest(
    path: string,
    options: RequestInit = {}
  ): Promise<unknown> {
    const apiKey = getApiKey();
    const url = `${API_BASE}${path}`;
  
    const response = await fetch(url, {
      ...options,
      headers: {
        "Content-Type": "application/json",
        Authorization: `Bearer ${apiKey}`,
        ...options.headers,
      },
    });
  
    if (!response.ok) {
      const body = await response.text();
      throw new Error(`API error ${response.status}: ${body}`);
    }
  
    return response.json();
  }
