+Both stack‑traces come from very small compatibility issues in **your local copy** of the library.  
+Fixing them just needs two tiny edits.
+
+---
+
+## 1  `'Agent' object has no attribute 'mcp_servers'`
+
+`Agent.__init__()` used to take `mcp_servers`, but in your checkout that
+parameter line is commented out:
+
+```python
+# mcp_servers: List[MCPServerSseParams] = [],
+```
+
+Yet `handle_tool_init()` still refers to `self.mcp_servers`, so the
+attribute is missing when the object is created.
+
+### Patch
+
+```diff
+@@ class Agent:
+-        # mcp_servers: List[MCPServerSseParams] = [],
++        mcp_servers: Optional[list] = None,   # list[MCPServerSseParams]
+
+@@ def __init__(...):
+-        self.tools_list_dictionary = tools_list_dictionary
+-        # self.mcp_servers = mcp_servers
++        self.tools_list_dictionary = tools_list_dictionary
++        self.mcp_servers = mcp_servers
+```
+
+> *Nothing else has to change; the `exists(self.mcp_servers)` check will now
+> work, and you can pass `mcp_servers=[server_one]` from your smoke‑test.*
+
+---
+
+## 2  `ImportError: cannot import name 'NotRequired' from typing`
+
+`typing.NotRequired` only exists in **Python ≥ 3.11**.  
+On 3.10 you have to import it from **`typing_extensions`**.
+
+The top of `swarms/tools/mcp_integration.py` currently has:
+
+```python
+from typing import Any, Dict, List, Optional, TypedDict, NotRequired
+```
+
+### Patch
+
+```diff
+-from typing import Any, Dict, List, Optional, TypedDict, NotRequired
++from typing import Any, Dict, List, Optional
++from typing_extensions import NotRequired, TypedDict
+```
+
+(There is already a `typing_extensions` import later, so you can simply reuse
+it and remove `NotRequired` from the `typing` line.)
+
+> Make sure the wheel `typing‑extensions` is installed:
+> ```bash
+> pip install -U typing_extensions
+> ```
+
+---
+
+### After the fixes
+
+Your smoke‑test script should run:
+
+```python
+from swarms.tools.mcp_integration import MCPServerSseParams
+from swarms.prompts.agent_prompts import MATH_AGENT_PROMPT
+from swarms import Agent
+
+server_one = MCPServerSseParams(
+    url="http://127.0.0.1:6274",
+    headers={"Content-Type": "application/json"},
+)
+
+agent = Agent(
+    agent_name="Math‑Tester",
+    agent_description="Does arithmetic via MCP add tool",
+    system_prompt=MATH_AGENT_PROMPT,
+    max_loops=1,
+    mcp_servers=[server_one],
+    output_type="final",
+)
+
+print(agent.run("Use the add tool to add 2 and 2"))
+```
+
+---
+
+**Summary**
+
+* add the `mcp_servers` parameter back into `Agent.__init__`  
+* import `NotRequired` from `typing_extensions`, not `typing`
+
+After these two edits the “attribute missing” and “ImportError” messages
+disappear and the agent can reach the MCP server for your smoke‑test.
