}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": "enzyme-kinetics-calculator",
"arguments": {
"mode": "velocity",
"vmax": 1.5,
"km": 0.5,
"substrate": 0.5,
"dataPairs": "Format: S,v per pair (space/newline separated).\nExample:\n0.1,0.2\n0.2,0.33\n0.5,0.6\n1,0.8\n2,1.0",
"inhibition": "none",
"inhibitorConc": 0,
"ki": 0,
"decimalPlaces": 4
}
}
}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).
