Google ADK

Install

Code
pip install google-adk

---

Connect

Code
import asyncio
from google.adk.tools.mcp_tool import MCPToolset
from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams

MEWCP_API_KEY = "API_KEY"

async def main():
    toolset = MCPToolset(
        connection_params=StreamableHTTPConnectionParams(
            url="https://gateway.mewcp.com/personal/mcp",
            headers={"Authorization": f"Bearer {MEWCP_API_KEY}"},
        )
    )

    tools = await toolset.get_tools()
    print("Available tools:", [t.name for t in tools])
    # -> ["search", "get_schema", "list_accounts", "call_tool"]

    await toolset.close()

asyncio.run(main())

You get four tools rather than the tools of each app. Your agent uses them to reach every app you have connected. See How MewCP works.

Call a tool directly

Code
call_tool = next(t for t in tools if t.name == "call_tool")

result = await call_tool.run_async(
    args={
        "server_maskedId": "google-calendar",
        "tool_name": "list_events",
        "args": {
            "calendar_id": "primary",
            "time_min": "2026-01-15T00:00:00Z",
            "time_max": "2026-01-16T00:00:00Z",
        },
    },
    tool_context=None,
)
print(result)

If you have connected more than one account for the same app, add "alias": "work" to select one.

Use with an LLM agent

Pass the toolset to an LlmAgent and ADK calls tools automatically based on the model's decisions:

Code
from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool import MCPToolset
from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams

toolset = MCPToolset(
    connection_params=StreamableHTTPConnectionParams(
        url="https://gateway.mewcp.com/personal/mcp",
        headers={"Authorization": f"Bearer {MEWCP_API_KEY}"},
    )
)

agent = LlmAgent(
    model="gemini-2.0-flash",
    name="assistant",
    instruction="You are a helpful assistant with access to the user's connected apps.",
    tools=[toolset],
)

---

B2B: per-user credential routing

To route calls for different audience members, use a header_provider callable instead of static headers:

Code
MCPToolset(
    connection_params=StreamableHTTPConnectionParams(
        url="https://gateway.mewcp.com/personal/mcp",
    ),
    header_provider=lambda ctx: {
        "Authorization": f"Bearer {MEWCP_API_KEY}",
        "x-mewcp-enduser-id": ctx.session.state["user_id"],
    },
)

Where to find your values

Value	Where to get it
API_KEY	Dashboard -> API Keys
Connected apps	Dashboard -> Servers
