SimpleLocalize MCP Server
A Model Context Protocol server that enables users to manage translations for their applications through SimpleLocalize's localization platform via natural language prompts in Cursor.
Tools
create_translation_keys
Create translation keys in bulk for a project. This endpoint allows you to create multiple translation keys at once. You can create up to 100 translation keys in a single request. Each key must have a 'key' field, and optionally can include 'namespace' and 'description' fields. Args: keys: List of dictionaries containing key information with fields: - key (required): Translation key (max 500 chars) - namespace (optional): Namespace for the key (max 64 chars) - description (optional): Description for translators (max 500 chars)
update_translations
Update translations in bulk with a single request. This endpoint allows you to update multiple translations at once. You can update up to 100 translations in a single request. Each translation must specify the key, language, and text. Namespace is optional. Args: translations: List of dictionaries containing translation information with fields: - key (required): Translation key - language (required): Language code - text (required): Translation text (max 65535 chars) - namespace (optional): Namespace for the key
README
mcp-simplelocalize
A MCP (Model Context Protocol) server implementation for SimpleLocalize.
Usage
Install
curl -LsSf https://astral.sh/uv/install.sh | sh
- Clone the repository
git clone https://github.com/GalvinGao/mcp-simplelocalize.git
- Install dependencies
uv sync
- Configure Cursor
You may wish to put this at .cursor/mcp.json under your project root, since SimpleLocalize API Key is specific to a single project.
Don't forget to add it to your .gitignore file to avoid exposing your API key.

- Describe your project localization requirements under
.cursorrules. For example:
## Translations
- Put all translations under the `default` namespace
- Language codes supported by this project: `en-US`, `ja-JP`, `ko-KR`, and `zh-Hant`.
- (any other conventions you want the LLM to follow, e.g. key naming style, etc. or just give it some examples would work well)
- Done! Enjoy prompting something like "Localize this component and update it to SimpleLocalize".
