Instructions

Implementation Reference

• src/tools/webhooks.ts:50-57 (handler)

  Handler function that executes the delete_webhook tool logic. It sends a DELETE request to the OpenWA API with the session ID and webhook ID.

    async ({ sessionId, webhookId }) => {
      const data = await openwaClient({
        method: "DELETE",
        path: `/sessions/${sessionId}/webhooks/${webhookId}`,
      });
      return { content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }] };
    }
  );

• src/tools/webhooks.ts:42-49 (schema)

  Schema and registration for the delete_webhook tool. Defines the input schema with sessionId (string) and webhookId (string) parameters.

  "delete_webhook",
  {
    description: "Delete a webhook from a WhatsApp session",
    inputSchema: {
      sessionId: z.string().describe("Session ID"),
      webhookId: z.string().describe("Webhook ID to delete"),
    },
  },

• src/tools/webhooks.ts:41-57 (registration)

  Registration of the delete_webhook tool via server.registerTool() within the registerWebhookTools function.

  server.registerTool(
    "delete_webhook",
    {
      description: "Delete a webhook from a WhatsApp session",
      inputSchema: {
        sessionId: z.string().describe("Session ID"),
        webhookId: z.string().describe("Webhook ID to delete"),
      },
    },
    async ({ sessionId, webhookId }) => {
      const data = await openwaClient({
        method: "DELETE",
        path: `/sessions/${sessionId}/webhooks/${webhookId}`,
      });
      return { content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }] };
    }
  );

• src/client.ts:10-35 (helper)

  The openwaClient helper function used by the handler to make the HTTP DELETE request to the backend API.

  export async function openwaClient<T = unknown>(opts: RequestOptions): Promise<T> {
    const url = `${BASE_URL}${opts.path}`;
  
    const headers: Record<string, string> = {
      "Content-Type": "application/json",
      "X-API-Key": API_KEY,
    };
  
    const res = await fetch(url, {
      method: opts.method,
      headers,
      body: opts.body ? JSON.stringify(opts.body) : undefined,
    });
  
    const text = await res.text();
  
    if (!res.ok) {
      throw new Error(`OpenWA API ${res.status}: ${text}`);
    }
  
    try {
      return JSON.parse(text) as T;
    } catch {
      return text as T;
    }
  }

• src/index.ts:9-20 (registration)

  const server = new McpServer({ name: "openwa-mcp", version: "1.0.0" });
  
  registerSessionTools(server);
  registerMessageTools(server);
  registerBulkTools(server);
