EPICS Channel Access MCP Server

What the code does

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

            data = yaml.load(text, Loader=_strict_yaml_loader())  # noqa: S506 - a SafeLoader subclass

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: LABMCP_ADDRESS (Instrument address, e.g. serial:///dev/ttyUSB0 or tcp://192.168.1.50:5025), LABMCP_SIMULATE (Set to 1 to use the built-in simulator (no hardware)), LABMCP_READ_ONLY (Set to 1 to disable all state-changing tools), LABMCP_LIMITS (Safety limit overrides, e.g. max_temperature_c=80). The author declared them in the registry entry; get the values from the project itself.
