Ollang MCP in Grok Build

Grok Build is xAI’s terminal coding agent, available through the grok CLI. With Ollang MCP, Grok can make localization part of development, release, and CI workflows.

Setup

Install Grok CLI

Install the CLI:

curl -fsSL https://x.ai/cli/install.sh | bash

Grok Build requires SuperGrok or X Premium Plus.

Add Ollang MCP

Create or edit the user-scope ~/.grok/config.toml:

~/.grok/config.toml

[mcp_servers.ollang]
url = "https://mcp.ollang.com/mcp"

The remote server also supports headers and bearer_token_env_var when your setup requires them. You can set common options such as enabled, startup_timeout_sec, tool_timeout_sec, and tool_timeouts.

Inspect and authenticate

Run grok inspect to see the configuration sources and discovered MCP servers. On first use, Grok opens the Ollang OAuth 2.0 + PKCE sign-in flow in your browser.

Start a localization task

Ask Grok to use Ollang from an interactive session, or use -p for a headless script or CI job.

Use Cases

Keep locale files in sync

Compare src/i18n/en-US.json with the existing locale files. For every
missing string, create an Ollang document translation order for fr-FR and
ko-KR. Preserve ICU placeholders and report the order IDs in the pull
request summary.

Localize a product launch video

Use Ollang to create subtitle orders for https://example.com/launch.mp4
in Spanish, French, and Italian, then create AI dubbing orders for Spanish
and French. Apply the "Product Launch" custom instruction and show me the
source and target languages for each order.

Make localization CI-friendly

In headless mode, check Ollang orders from localization-orders.json. For
completed orders, download the translated files into the matching locale
directories. If an order failed, report it without changing the repository.

Project-level .grok/config.toml files can contribute [mcp_servers], [plugins], and [permission] settings. Keep shared Ollang configuration in user scope when you want it available across projects, and use grok inspect before troubleshooting discovery.
