Connect Claude API to Nodes2Cloud

The Messages API MCP connector.

Claude 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

Claude 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.

TypeScript

import Anthropic from "@anthropic-ai/sdk";
