ChatGPT

Connect ChatGPT to emisar through Developer mode over remote MCP. OAuth signs you in — you do not need to copy an agent key.

Using Claude Code, Cursor, Claude Desktop, or a CLI instead? Those connect through the emisar-mcp stdio bridge — see Connect a CLI agent. For Claude.ai, see Claude.ai.

Add the connector#

ChatGPT reaches a custom MCP server through Developer mode. Access depends on your account and workspace policy.

1. Open Settings → Security and login. Turn on Developer mode.
2. Open ChatGPT Plugins and select the small + button just right of the search box — it is easy to miss.
3. Fill the form:
   • Name — paste the name below
   • Description (optional) — "Run approved infrastructure actions on my fleet."
   • Connection → Server URL — paste the URL below
   • Authentication — choose OAuth. There is no client ID or secret to paste; emisar registers the connector itself.

   Select Create, then review the discovered tools and metadata.

4. ChatGPT opens the emisar sign-in page. Sign in and choose Authorize. ChatGPT then lists the emisar tools.
5. Review the connection permissions. emisar policy, approvals, and audit still apply to every call.
6. Start a new chat. Add emisar from the tools menu. A listed tool means metadata access only. Adding the connection lets the chat call those tools.
7. After a tool metadata change, open the plugin connection. Refresh its tool metadata before the next test.

Verify the connection#

1. Ask the client to run linux.uptime on any one of the connected runners.
2. Confirm that the client returns the action output.
3. Open Audit. Confirm that the event records the client, runner, action, and reason.

What the sign-in grants#

The consent screen mints a key bound to your membership. The connector acts as you. Every call is attributed to you and the agent you are using. It reaches only the runners and actions your own access already allows (how a key inherits its operator's scope). Revoke it any time from AI agents in the console, or from the connector settings in Claude or ChatGPT.
