mcp.json

{
  "mcpServers": {
    "elysiatools-audio-recorder": {
      "name": "audio-recorder",
      "description": "Record audio directly from your microphone with real-time waveform visualization and download options",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=audio-recorder",

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "audio-recorder",
    "arguments": {
  "outputFormat": "webm",
  "sampleRate": "44100",
  "bitrate": "128",
  "enableVisualization": true
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
