# Connect Claude.ai

This guide connects **Claude.ai** (the web app) to your WHMCS through Relyagent. Relyagent turns
WHMCS into a self-hosted **MCP server** — an open standard that lets AI assistants call external
tools — so Claude can list and call only the WHMCS tools you allow.

## Prerequisites

* A **connection** created under **Addons → Relyagent → MCP Clients** — see
  [Configuration](/relyagent-whmcs/configuration).
* Its **Client ID** and **Client Secret** (the secret is shown only once at creation).
* The shared **Endpoint URL**:

  ```
  https://<your-whmcs>/modules/addons/relyagent/public/mcp/endpoint.php
  ```

::: tip Grab the exact values from WHMCS
The **Setup** tab (**Addons → Relyagent → Setup**) has a Claude.ai accordion with the Endpoint
URL pre-filled and copy-paste steps.

## Add Relyagent as a custom connector

1. In **Claude.ai**, open **Settings → Connectors**.
2. Add a **custom connector** and paste the **Endpoint URL** above as the connector's server URL.
3. When prompted for credentials, enter the connection's **Client ID** and **Client Secret**.

## Authorize and consent

Claude.ai auto-discovers Relyagent's OAuth endpoints and starts sign-in:

1. You're sent to your **native WHMCS admin login** — your existing 2FA, brute-force and IP
   rules apply, because Relyagent shows no login form of its own.
2. A **consent screen** lists this connection's tools. Approve it to finish.

## Verify it works

Ask Claude what WHMCS tools it has. It should list **only** the tools you ticked for this
connection — nothing more. Any tool outside that set is rejected.

::: warning If it won't connect
Make sure you pasted **both** the Client ID and Client Secret — the Endpoint URL alone isn't
enough. Confirm you signed in at the WHMCS admin login and approved consent, and double-check the
exact Endpoint URL. See the [error reference](/relyagent-whmcs/errors).
