# Connect Codex to Wikilayer

<!-- block:43582 -->
## Add the MCP server

From a terminal:

```bash
codex mcp add wikilayer --url https://wikilayer.org/mcp
codex mcp login wikilayer
```

The first command stores the Wikilayer endpoint. The second opens browser authorization; sign in to Wikilayer and approve access.

<!-- block:43583 -->
## Check the connection

Start a new Codex session and try [a first question](block:5548). If Codex lists your wikis or their structure, the MCP connection is ready.

<!-- block:43584 -->
## Install the skills

[Wikilayer skills](block:8219) add repeatable lint, review, and translation workflows. To help keep your wikis in order, we recommend installing them:

```bash
codex plugin marketplace add wikilayer/skills
codex plugin add wikilayer@wikilayer
```

Start a new session after installation. The workflows are available as `$wikilayer:lint`, `$wikilayer:review`, and `$wikilayer:translations`.

<!-- block:43586 -->
## Update the skills

Refresh the Git marketplace, then reinstall the plugin:

```bash
codex plugin marketplace upgrade wikilayer
codex plugin remove wikilayer@wikilayer
codex plugin add wikilayer@wikilayer
```

Start a new session to load the updated skills.
