Frequently asked questions

How do I create an OSC endpoint?

Use the `create_osc_endpoint` tool with a port number (1024–65535) and optional buffer size (max 10,000) and address filters.

How can I see received messages?

Use `get_osc_messages` tool; you can filter by endpoint, address pattern, time window, and limit (max 1000 messages).

Can I filter which OSC messages are stored?

Yes, when creating an endpoint you can provide an `addressFilters` array to only store messages matching certain OSC address patterns.

How do I stop an endpoint?

Use the `stop_osc_endpoint` tool with the endpoint ID returned when you created it.

What transport does the server use?

The server uses stdio for MCP communication and UDP for OSC message reception.
