Quick test with curl

Terminal

curl -s -X POST https://whisper-mcp.marsaplatform.com/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"test","version":"1"}}}'

With a valid key you get the initialize result. Without a key you get 401.

Tools

The original page states: “7 MCP tools”. The full list is generated from tools/list once a read key is configured for this site; until then any MCP client shows it after you connect.

FAQ

What is the difference between a read and a write key?

read covers status and jobs only; write adds transcription and translation.

Maximum length?

Up to two hours or 200 MB for a link, and 25 MB for an uploaded file.

How do I get a key?

Request an access key from the key request page (Arabic form).

401 Unauthorized

The real response for a request without a key:

HTTP/2 401 · application/json

WWW-Authenticate: Bearer

{"error": "unauthorized"}

Send the header exactly as Authorization: Bearer YOUR_API_KEY.
