+### Why you’re getting the `ImportError`
+
+`fastmcp` ≥ ​2.0 renamed **`FastClientSession`** → **`Client`** and moved it into the top‑level package.  
+So
+
+```python
+from fastmcp import FastClientSession          # 🚫 no longer exists
+```
+
+now raises the exact error you see.
+
+---
+
+### Quick fix ‑ patch the import
+
+Open **`swarms/tools/mcp_integration.py`** and replace the first import block:
+
+```python
+# OLD
+from fastmcp import FastClientSession as ClientSession
+```
+
+with
+
+```python
+# NEW – works with fastmcp ≥ 2.0
+from fastmcp import Client as ClientSession
+```
+
+*(If you need to stay on fastmcp 1.x, install the old version instead:  
+`pip install "fastmcp<2"` and keep your original import.)*
+
+---
+
+### Minimal working smoke‑test
+
+```python
+# examples/mcp_example/mcp_client.py
+import asyncio
+from swarms import Agent
+from swarms.prompts.agent_prompts import MATH_AGENT_PROMPT
+from swarms.tools.mcp_integration import MCPServerSseParams
+
+# 1. describe the remote MCP server you want to hit
+server = MCPServerSseParams(
+    url="http://localhost:6274",                 # or any public MCP SSE endpoint
+    headers={"Content-Type": "application/json"}
+)
+
+# 2. create a Swarms agent and hand it the server list
+math_agent = Agent(
+    agent_name="Math‑MCP‑Tester",
+    system_prompt=MATH_AGENT_PROMPT,
+    max_loops=1,
+    mcp_servers=[server],        # <‑‑ now recognised
+    output_type="final",
+)
+
+# 3. run a call that should trigger the server’s “add” tool
+result = math_agent.run("Use the add tool to add 2 and 2")
+print("🟢 RESULT:", result)
+```
+
+---
+
+### Extra housekeeping
+
+1. **Expose `mcp_servers`**  
+   In your current `Agent.__init__` the assignment line is commented out:
+
+   ```python
+   # self.mcp_servers = mcp_servers      # <- uncomment
+   ```
+
+   Make sure the attribute exists before it is accessed in `handle_tool_init()`.
+
+2. **Python < 3.11 + `NotRequired`**  
+   Keep
+
+   ```python
+   from typing_extensions import NotRequired
+   ```
+   (You already changed this – good.)
+
+3. **Install / upgrade fastmcp**
+
+   ```bash
+   pip install -U fastmcp           # latest 2.x
+   # or, for the old API:
+   # pip install "fastmcp<2"
+   ```
+
+---
+
+### What if you don’t have your own server yet?
+
+Until you spin up the Browserbase example (or any other MCP server), you can test against the **FastMCP public demo**:
+
+```python
+demo = MCPServerSseParams(url="https://demo.fastmcp.io/sse")
+```
+
+It exposes trivial arithmetic tools (`add`, `multiply`, …) that match the smoke‑test above.
+
+That’s all you need to get your Swarms agent talking to an existing MCP server without touching server‑side code. 🚀
