Connect from Claude.ai, ChatGPT or Codex

Metrx has an MCP connector you add by URL and sign in to with your Metrx account. The app you connect registers itself with Metrx’s sign-in server, you approve it once, and no API key is copied into the app.

https://metrxbot.com/api/mcp/connect

The same URL is on Settings → Integrations in the dashboard, with a copy button.

Claude.ai

Pro or Max: open Customize → Connectors, choose + Add → Add custom connector, paste the URL above and save. Then choose Connect, sign in to Metrx and approve.

Team or Enterprise: an owner adds the connector once for the organization: Organization settings → Connectors → Add → Custom → Web, paste the URL, and under OAuth client choose Register automatically. Each member then opens Customize → Connectors and chooses Connect.

ChatGPT

Open the plugins page at chatgpt.com, choose + then Add custom MCP server, paste the URL above as the Server URL and choose OAuth. ChatGPT registers itself with Metrx automatically. Confirm, create it, install it, and sign in to Metrx when asked.

Codex

Add the Metrx marketplace and install the plugin:

codex plugin marketplace add metrxbots/mcp-server
codex plugin add metrx@metrxbots

Sign in to Metrx when Codex asks. The plugin points at the URL above with OAuth and dynamic client registration.

What the connector can do

The connector acts as you, inside your current organization, with your role. A member still cannot do what only an owner or admin can (for example retire an agent).

It serves every Metrx MCP tool except buy_verification, which stays on an API key. Asked for “the workforce review”, it reviews your own org; ask for the Northwind sample to see the demo.

It cannot reach anything the tools do not use. API keys, billing, team members and organization settings stay in the dashboard; the connector is refused on those routes even if you are an owner.

API key instead

Scripts, CI and MCP clients without OAuth keep using an API key against https://metrxbot.com/api/mcp (see MCP Server and The Manager’s Desk). Both endpoints serve the same tools.
