How to Use the Crowdin MCP in Claude Code

Q: How do I check Crowdin translation status from a GitHub Action using Claude Code?

In your workflow YAML, add a step that runs claude mcp with the listprojectfiles tool. You can parse the JSON output to check the translationProgress for each file and act accordingly.

Q: Can I use Claude Code to see which languages are supported by Crowdin?

Yes. Run claude mcp with the listsupportedlanguages tool. It will output a list of all language codes and names that Crowdin can handle.

Q: What's the command to connect the Crowdin MCP server to Claude Code?

Run claude mcp add --transport http crowdin -- . Then you can use claude mcp rpc crowdin.listprojects to start making calls.

Q: Can I use this to back up my Crowdin translation memories with Claude Code?

This server lets you list TMs with listtranslationmemories to get their IDs and segment counts. It doesn't provide a tool for downloading the actual TM file content itself.

Pipe your Crowdin localization data directly into the terminal. This headless MCP server is built for your CI/CD pipelines and shell scripts.

Automate Localization QA in CI

Add a QA step to your build pipeline that checks your Crowdin project status. A simple script can use `list_project_files` to check for files with low translation coverage or `list_project_tasks` to find stalled proofreading tasks. If a file's translation progress is below 90%, you can fail the build. This MCP Server lets your CI system talk directly to Crowdin, catching localization issues before they hit production.

Script Project Health Checks

Write a shell script that runs nightly via cron. It can connect to this MCP server to perform health checks on your entire Crowdin account. Use `list_projects` and `get_project_details` to make sure every project has target languages defined. Chain that with `list_translation_memories` to confirm that each project is linked to a TM. You can pipe the output to a log file or send a notification if something's wrong. It’s set-and-forget monitoring for your localization workflow.

Headless Reporting for Claude Code

Don't log into the web UI just to download a report. Use `claude mcp` with the `list_project_reports` tool to pull data directly into your terminal. Pipe the output to `jq` to parse it or send it to another service. This is perfect for automated financial tracking or for sending weekly progress summaries to a Slack channel. You get the data you need, where you need it, with no manual steps.
