# Codex CLI Setup

> Add Slashy MCP to Codex CLI by editing ~/.codex/config.toml.

Codex CLI reads MCP servers from a TOML config file at `~/.codex/config.toml`.

## Setup

<Steps>
  <Step title="Open the Codex config file">
    In your terminal, open the file in your editor:

    ```bash theme={null}
    nano ~/.codex/config.toml
    ```

    If the file does not exist, create it.

  </Step>

  <Step title="Add the Slashy server">
    Paste this block at the end of the file:

    ```toml theme={null}
    [mcp_servers.slashy]
    url = "https://slashy.ctrlcenter.ai/mcp"
    ```

    Save and exit.

  </Step>

  <Step title="Start Codex and approve OAuth">
    Run `codex` in your terminal. On first launch, it opens your browser to the Slashy login page. Sign in with Google and click **Allow**.

    </Frame>
  </Step>

  <Step title="Verify the connection">
    Inside Codex, type `/mcp`. You should see **slashy** listed as connected with its tools visible.

## What happens after setup

Codex caches the OAuth token in `~/.codex/auth/`. It refreshes automatically on expiry.
