}
}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": "audio-dual-channel-signal-generator",
"arguments": {
"sampleRate": "48000",
"durationSeconds": 0.5,
"fadeMs": 10,
"noiseSeed": 1,
"leftWaveform": "sine",
"leftFrequencyHz": 440,
"leftEndFrequencyHz": 440,
"leftSweep": "constant",
"leftPhaseDegrees": 0,
"leftLevelDbfs": -18,
"rightWaveform": "sine",
"rightFrequencyHz": 880,
"rightEndFrequencyHz": 880,
"rightSweep": "constant",
"rightPhaseDegrees": 0,
"rightLevelDbfs": -18
}
}
}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).
