      "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": "image-trim-color",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "presetColors": "white",
  "trimColor": "Select color to trim...",
  "sampleFrom": false,
  "samplePosition": "top-left",
  "colorTolerance": 30,
  "analyzeOnly": false,
  "format": "original",
  "quality": 90
}
  }
}

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.
