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-color-picker",
"arguments": {
"imageFile": "https://example.com/file.ext",
"x": 0,
"y": 0,
"sampleRadius": 0,
"outputFormat": "all"
}
}
}
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). | Choose which color format(s) to include in the output |
File-type parameters must be uploaded first via POST /upload/image-color-picker, then the returned filePath is passed to the corresponding file field.
