Connect Google ADK to Nodes2Cloud

Agent Development Kit's McpToolset.

Google ADK talks to the Nodes2Cloud MCP server at https://api.nodes2cloud.com/mcp over Streamable HTTP. Once connected, your agent can read the node catalogue, write and check workflows, and request deploys that wait for your approval by default.

Use a Personal Access Token

Google ADK connects with a Personal Access Token. Create one in the editor under Integrations → MCP server → Headless & CI Tokens, then Generate Token. Replace n2c_pat_YOUR_TOKEN below with it. The code reads it from the N2C_API_KEY environment variable.

Treat the token like a password and keep it out of source control.

Python

python

import os
from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset

nodes2cloud = McpToolset(
    connection_params=StreamableHTTPConnectionParams(
        url="https://api.nodes2cloud.com/mcp",
        headers={"Authorization": f"Bearer {os.environ['N2C_API_KEY']}"},
    ),
)
# Pass tools=[nodes2cloud] to your Agent.
