+### What happened?
+
+The Replit auto‑merge put **two very different things in one file**:
+
+1. **FastMCP server code** (`add / multiply / divide` tools)  
+2. **Client/Agent code** that is supposed to *call* those tools
+
+That hybrid script can’t work correctly:
+
+* The moment `mcp.run()` starts the SSE server loop, the code **after it never executes**, so the `Agent` you created would never run.  
+* Even if it did, you’d be pointing the client back to *itself* on the same port—nothing useful.
+
+---
+
+### Correct separation
+
+| File | Role | Runs in its own process |
+|------|------|-------------------------|
+| **`math_server.py`** | Hosts the tools (`@mcp.tool()`), listens on :8000 | ✅ |
+| **`math_agent.py`**  | Swarms `Agent` that talks to that server | ✅ |
+
+---
+
+#### 1 . `math_server.py` – *server‑only*
+
+```python
+# math_server.py
+from fastmcp import FastMCP
+import time
+
+mcp = FastMCP("Math‑Mock‑Server")
+
+@mcp.tool()
+def add(a: int, b: int) -> int:
+    time.sleep(0.1)
+    return a + b
+
+@mcp.tool()
+def multiply(a: int, b: int) -> int:
+    time.sleep(0.1)
+    return a * b
+
+@mcp.tool()
+def divide(a: int, b: int) -> float:
+    if b == 0:
+        raise ValueError("Cannot divide by zero")
+    time.sleep(0.1)
+    return a / b
+
+if __name__ == "__main__":
+    print("🚀 Math MCP server on :8000")
+    mcp.run(transport="sse", host="0.0.0.0", port=8000)
+```
+
+(`server.py` never imports `Agent` or `MCPServerSseParams`.)
+
+---
+
+#### 2 . `math_agent.py` – *client/agent‑only*
+
+```python
+# math_agent.py
+from swarms import Agent
+from swarms.tools.mcp_integration import MCPServerSseParams
+
+MATH_SERVER = MCPServerSseParams(
+    url="http://127.0.0.1:8000",           # no “/mcp” path required
+    headers={"Content-Type": "application/json"},
+)
+
+agent = Agent(
+    agent_name="Math-Processing-Agent",
+    agent_description="Specialised agent for basic math ops",
+    system_prompt=(
+        "You can use the add, multiply and divide MCP tools "
+        "to answer any arithmetic question."
+    ),
+    max_loops=1,
+    mcp_servers=[MATH_SERVER],
+    model_name="gpt-4o-mini",
+    output_type="final",
+)
+
+if __name__ == "__main__":
+    answer = agent.run("Use the add tool to add 2 and 2")
+    print("Agent replied ➜", answer)
+```
+
+---
+
+### How to run (locally or on Replit)
+
+```bash
+# Terminal 1  (or first Replit tab)
+python math_server.py
+
+# Terminal 2  (second tab)
+python math_agent.py
+```
+
+Expected console:
+
+```
+🚀 Math MCP server on :8000
+Agent replied ➜ 4
+```
+
+---
+
+### Key points to remember
+
+1. **Never start an Agent in the same process that is serving MCP**—keep client and server separate.  
+2. `MCPServerSseParams.url` points to the **root** of the FastMCP server, not `/mcp`.  
+3. The Swarms base `Agent` already knows how to wrap the JSON‑RPC call; you only supply `mcp_servers=[…]`.
+
+Follow that structure, and your manager’s “initialize the agent like this” requirement is fully satisfied.
