2. MCP Server Setup

First, generate an API key (sk_...) in your account at transcreva.net/conta under Chaves de API e MCP (available on the Ilimitado plan).

Option A: Remote HTTP MCP Server (https://transcreva.net/api/mcp)

Zero local installation required. Works with any MCP client supporting Streamable HTTP:

Claude Code

claude mcp add --transport http transcreva https://transcreva.net/api/mcp \
  --header "Authorization: Bearer $TRANSCREVA_API_KEY" --scope user

Cursor (~/.cursor/mcp.json)

{
  "mcpServers": {
    "transcreva": {
      "url": "https://transcreva.net/api/mcp",
      "headers": {
        "Authorization": "Bearer ${env:TRANSCREVA_API_KEY}"
      }
    }
  }
}

Option B: Local Stdio MCP Server (Supports Local File Uploads up to 2 GB)

Use the local stdio server when you want your AI assistant to directly upload and transcribe local .mp3, .m4a, .wav, .ogg, .opus, .mp4, .mov, or .webm files from your disk:

{
  "mcpServers": {
    "transcreva": {
      "command": "node",
      "args": ["/path/to/transcreva-mcp/bin/transcreva-mcp.mjs"],
      "env": {
        "TRANSCREVA_API_KEY": "sk_..."
      }
    }
  }
}
