# Connect Claude Code

Connect **Claude Code** to your WHMCS through Relyagent's self-hosted **MCP server**, so Claude Code 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 Code accordion with the Endpoint
URL pre-filled and copy-paste steps.

## Add Relyagent as an MCP connector

1. In **Claude Code**, add the server (the Endpoint URL is the same for every connection):

   ```
   claude mcp add --transport http relyagent \
     https://<your-whmcs>/modules/addons/relyagent/public/mcp/endpoint.php
   ```
2. Supply the connection's **Client ID** and **Client Secret** via the OAuth flags — run
   `claude mcp add --help` for the exact option names in your Claude Code version, or use
   `claude mcp add-json` with an `oauth` block.
3. Inside Claude Code, run `/mcp` → **Authenticate** to start sign-in.

## Authorize and consent

Claude Code 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 Code to list its available WHMCS tools. It should show **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 provided **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).
