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": "video-compressor",
    "arguments": {
  "videoFile": "https://example.com/file.ext",
  "crf": 23,
  "preset": "medium",
  "scalePercent": 100,
  "outputFormat": "mp4",
  "audioBitrate": 128,
  "removeAudio": false
}
  }
}

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).
