Claude Code connects to remote MCP servers over HTTP and signs in with OAuth. Pick one of the two ways below.

​
Option A — the Profit with Purpose plugin

The public Profit with Purpose skills repository is also a Claude Code plugin marketplace. The plugin adds the connector, the skills, and the /ecn-connect and /ecn-status commands, and it updates from the marketplace.
Then run /ecn-connect. The first tool call opens Earth Care Network’s sign-in in your browser.

​
Option B — the connector alone

1

Add the server

2

Sign in

Start Claude Code, run /mcp, choose earth-care-network, and sign in to Earth Care Network in the browser. Pick the scopes the connection may use.
3

Use it

Ask, for example:
Help me get my enterprise on Earth Care Network.

​
Share it with a project

--scope project writes the server to the project’s .mcp.json, so everyone who opens the project gets it. With OAuth there is no secret in that file; each person signs in as themselves.

​
Without a browser (scripts, CI)

Use an API key from the portal (Settings → Developers, open it) as a header instead of OAuth. Use this too if the browser sign-in fails after Claude Code restarts on a new port:
An ecn_mcp_… key acts as you. Never commit one; read it from an environment variable or your secret manager.

​
Remove it

​
Troubleshooting

  • No tools, or “Unauthorized” — the sign-in did not finish. Run /mcp and sign in again. With a key, check the Bearer prefix.
  • Is the server up? curl -s https://www.earthcare.network/mcp/health/ answers {"ok": true, …}. It does not list tools — that needs a signed-in connection.
  • insufficient_scope — reconnect and grant that scope.
  • human_only — working as designed: the answer’s portal_url is where you publish, send or pay yourself.
