Autonomous AI agents running in **Claude Desktop**, **Cursor**, **Windsurf**, or **Antigravity** are transforming software engineering and sysadmin workflows. However, when an agent completes a 45-minute build, encounters a critical deployment exception, or discovers an uncommitted bug, it has no native, secure way to ping you.

Giving an LLM direct shell execution with raw `curl` commands is notoriously brittle:

The standardized solution is **Model Context Protocol (MCP)**, Anthropic's open protocol for connecting AI models to external tools and services.

In this tutorial, we will walk through how **OmniBridge MCP** was built in pure Python to deliver resilient, multi-channel notifications (Telegram, Discord, WhatsApp, Slack) with offline queueing.

Most naive MCP integrations make direct, synchronous HTTP requests. If the endpoint is down or throttles the connection, the agent throws an unrecoverable tool call error.

OmniBridge implements an enterprise resilience layer:

```
[ AI Agent: Claude / Cursor / Antigravity ]
                      │  JSON-RPC 2.0 (stdio)
                      ▼
            [ OmniBridge MCP Server ]
                      │
           [ Token Bucket Rate Limiter ]

     │                │                │
     └────────────────┴────────────────┘
                      │
           (On API Timeout or 429)
                      ▼
     [ Persistent SQLite WAL Queue ]
                      │
       (Exponential Backoff Worker)
```

Rather than adding heavy framework dependencies, an MCP server can be built with standard JSON-RPC 2.0 over standard input and output (`sys.stdin` / `sys.stdout`).

``` python
import sys
import json
import logging

logging.basicConfig(level=logging.INFO, stream=sys.stderr)

class MCPServer:
    def __init__(self):
        self.server_name = "omnibridge-mcp"
        self.server_version = "1.0.0"

    def handle_request(self, req):
        method = req.get("method")
        req_id = req.get("id")

        if method == "initialize":
            return {
                "jsonrpc": "2.0",
                "id": req_id,
                "result": {
                    "protocolVersion": "2024-11-05",
                    "capabilities": {"tools": {}},
                    "serverInfo": {"name": self.server_name, "version": self.server_version}
                }
            }
        elif method == "tools/list":
            return {
                "jsonrpc": "2.0",
                "id": req_id,
                "result": {"tools": self.get_tools()}
            }
        # Dispatches tools/call...
```

Using `httpx`, we deliver rich messages to Telegram chats and Discord channels:

``` python
import httpx

def send_telegram_alert(bot_token: str, chat_id: str, text: str):
    url = f"https://api.telegram.org/bot{bot_token}/sendMessage"
    payload = {"chat_id": chat_id, "text": text, "parse_mode": "Markdown"}
    with httpx.Client(timeout=10.0) as client:
        return client.post(url, json=payload).json()
```

Connect the server in your `claude_desktop_config.json`:

```
{
  "mcpServers": {
    "omnibridge": {
      "command": "python",
      "args": ["-m", "omnibridge.server"],
      "cwd": "/path/to/omnibridge-mcp",
      "env": {
        "TELEGRAM_BOT_TOKEN": "your_bot_token",
        "DISCORD_WEBHOOK_URL": "https://discord.com/api/webhooks/..."
      }
    }
  }
}
```

Now you can instruct Claude or Cursor:

*"Run the build pipeline. If any test fails, notify me immediately on Telegram with the error trace."*

For business-critical agent setups, missing notifications is not an option. The production tier features:

`delay = (2 ** retry_count) * 5 seconds`
