Server configuration
Add this block to your MCP client configuration:
mcp.json
{
"mcpServers": {
"elysiatools-image-channel": {
"name": "image-channel",
"description": "Extract, manipulate, and analyze individual color channels (RGB, Alpha, Luminance) with professional processing options",
"baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=image-channel",
"command": "",
"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": "image-channel",
"arguments": {
"imageFile": "https://example.com/file.ext",
"channel": "red",
"operation": "extract",
"intensity": "100",
"outputMode": "single",
"format": "original",
"quality": 95
}
}
}
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). | quality | number | No | Output quality for lossy formats |
File-type parameters must be uploaded first via POST /upload/image-channel, then the returned filePath is passed to the corresponding file field.
