Model Context Protocol (MCP) gives Agents the ability to interact with external systems through a standardized interface. You can give your agents access to tools from MCP servers using MCPTools. When using MCPTools within AgentOS, the lifecycle is automatically managed. No need to manually connect or disconnect the MCPTools instance.
mcp_tools_example.py
from agno.agent import Agent
from agno.os import AgentOS
from agno.tools.mcp import MCPTools

# Create MCPTools instance
mcp_tools = MCPTools(
    transport="streamable-http", 
    url="https://docs.agno.com/mcp"
)

# Create MCP-enabled agent
agent = Agent(
    id="agno-agent",
    name="Agno Agent",
    tools=[mcp_tools],
)

# AgentOS manages MCP lifespan
agent_os = AgentOS(
    description="AgentOS with MCP Tools",
    agents=[agent],
)

app = agent_os.get_app()

if __name__ == "__main__":
    # Don't use reload=True with MCP tools to avoid lifespan issues
    agent_os.serve(app="mcp_tools_example:app")
This does not automatically refresh connections that are interrupted or restarted, you can use refresh_connection to do so.
If you are using MCPTools within AgentOS, you should not use reload=True when serving your AgentOS. This can break the MCP connection during the FastAPI lifecycle.
See here for a full example.
