Parameters

Name	Type	Required	Description

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-hall-reverb",
    "arguments": {
  "audioFile": "https://example.com/file.ext",
  "hallSize": 0.8,
  "decayTime": 2.5,
  "diffusion": 0.7,
  "damping": 0.4,
  "preDelay": 100,
  "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).
