Overview

This MCP server bridges AI assistants with Weblate, enabling natural language interaction for translation management, project oversight, and content updates.

This MCP server provides both read and write access to Weblate data, making it convenient but requiring careful configuration. It's safe when used with a well-defined AI assistant and secure API token management. Risky scenarios involve poorly configured AI leading to unintended data modifications.

Performance depends on the Weblate API's responsiveness. Efficient filtering using searchUnitsWithFilters is crucial for large projects.

Cost is primarily determined by Weblate API usage. Be mindful of the number of API calls, especially when performing bulk operations.

Known Risks

!Exposure of Weblate API token if not properly secured.
!Unintended modifications to translations due to AI errors.
!Potential for denial-of-service if rate limiting is insufficient.
!Data breaches if the Weblate instance itself is compromised.

Safety Score

moderate risk

Positive

+API token authentication required
+Input validation with Zod schemas
+Rate limiting and retry logic implemented
+HTTPS support for secure communication

Risks

-Write access to translation data
-Potential for unintended modifications via AI
-Exposure of API token if not handled securely
-No explicit RBAC beyond Weblate's own system
-No sandboxing of execution environment

FAQ

How do I secure my Weblate API token?

Store the API token as an environment variable and restrict access to the server's configuration.

Can I use this server with a self-hosted Weblate instance?

Yes, configure the `WEBLATE_API_URL` environment variable to point to your instance.

What happens if the Weblate API is unavailable?

The server implements retry logic, but prolonged outages may result in errors.

How can I limit the AI's access to specific projects?

Configure the AI assistant to only use tools with the appropriate project slugs.

Does this server support OAuth?

No, it currently only supports API token authentication.

How do I troubleshoot connection issues?

Check the `WEBLATE_API_URL` and `WEBLATE_API_TOKEN` environment variables, and verify that the Weblate instance is accessible from the server.

Can I use this server to translate files directly?

No, this server interacts with Weblate's API, which manages translations within the platform.
