mcp.json
{
  "mcpServers": {
    "elysiatools-audio-vinyl-crackle": {
      "name": "audio-vinyl-crackle",
      "description": "Add vinyl crackle noise to an audio file",

      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

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-vinyl-crackle",
    "arguments": {
  "audioFile": "https://example.com/file.ext",
  "crackleType": "light",
  "intensity": 0.4,
  "density": 0.6,
  "frequencyRange": "mid",
  "warmth": 0.3,
  "mix": 0.7,
  "outputFormat": "mp3"
}
  }
}
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).
File parameters accept a public file URL only (https://…). Local paths, data: URIs, and Base64 strings are not supported.
