SubtitlePop MCP — SRT & WebVTT Subtitle Tools
Check subtitle timing, convert SRT/WebVTT, shift timestamps and extract transcripts from your MCP client.
A local, open-source companion from SubtitlePop. No API key, account, model or paid credits are required. The server processes subtitle text over stdio. It does not open paths, fetch URLs, write files or call SubtitlePop's commercial backend.
Quick start
Requires Node.js 22+ and an MCP client that supports local stdio servers.
{
"mcpServers": {
"subtitlepop": {
"command": "npx",
"args": ["-y", "subtitlepop-mcp@0.1.0"]
}
}
}
This is the common mcpServers configuration shape; consult your client's settings for the exact configuration file. Restart or reconnect the client after adding it. On Windows, if your client cannot spawn npx, install the package locally and point command at node and args at the absolute installed src/cli.js path. The package itself does not need a shell.
npx -y subtitlepop-mcp@0.1.0 --help
