Perplexity

Control the CaptionHub MCP Server from chat.

Project management usually means clicking through ten different browser tabs. You just ask Claude to pull up your pending video localizations. The agent runs `list_projects` and shows you exactly what needs attention today. Need to kick off a new batch? Tell your AI client to spin up the work. It hits `create_project` with your source video details, then fires `transcribe_video` to get the base text rolling immediately.

Review and approve caption sets instantly.

Waiting for translations slows down the whole release cycle. Claude checks the status of specific languages using `get_project_details`. You see the exact progress metrics right in your conversation window. When the text looks good, you tell the agent to greenlight it. Running `approve_captions` locks in the translation, and `export_captions` hands you the final URL to download the subtitle files.

Keep your workspace organized.

Old localization tasks clog up your dashboard over time. You can clear out the noise by asking Claude to run `archive_project` on anything completed last quarter. Administrators also get quick visibility into the backend via the MCP integration. Firing `list_webhooks` lets you verify your routing is still active, while `get_account_info` pulls your current usage limits without making you dig through billing settings.
