What launched
- InstantTranscriber says you can now connect an MCP-compatible AI assistant to it, to transcribe a recording, retrieve a YouTube video's existing captions, or turn a transcript into notes in the same conversation. [1]
How to connect
- The server URL is https://api.instanttranscriber.com/mcp, added as a remote Streamable HTTP MCP server, with OAuth sign-in to an InstantTranscriber account (a Free account works). [1] [2]
- InstantTranscriber notes that your assistant must support remote MCP and OAuth, and that availability depends on the assistant and workspace settings. [1]
- Input is a public audio or video URL, or a file uploaded through the REST API whose transcription ID you give the assistant. Files attached to a chat are not automatically shared with the MCP server. [1]
Allowances
- Stated allowances: Free 1 audio hour per UTC calendar month; Premium 15 audio hours per billing month (up from 8); API Plan 100 audio hours per billing month. API and MCP use draw from the same balance. [1]
YouTube captions vs transcription
- Fetching a video's existing captions uses zero audio hours. Transcribing a video's audio is a normal transcription job and counts against the allowance. [1]
- InstantTranscriber says caption retrieval never silently switches to audio transcription, and that private, restricted and live videos are not guaranteed to work. [1]
Output
- Completed results are available as TXT, SRT or VTT. Long results come back in pages, and the assistant can list recent jobs and check the remaining allowance. [1]
What this page does not cover
We have not connected an assistant to this server. Transcription accuracy and how individual AI assistants handle the connection are not covered here.
