Connect OpenAI API to Nodes2Cloud

The Responses API's hosted MCP tool.

OpenAI API 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

OpenAI API 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 openai import OpenAI

client = OpenAI()
response = client.responses.create(
    model="gpt-5",
    input="List my Nodes2Cloud workflows.",
    tools=[{
        "type": "mcp",
        "server_label": "nodes2cloud",
        "server_url": "https://api.nodes2cloud.com/mcp",
        "authorization": os.environ["N2C_API_KEY"],
        "require_approval": "always",
    }],
)
print(response.output_text)
