EPICS MCP Server

What is EPICS-MCP-Server?

EPICS-MCP-Server is a Python-based server that integrates with EPICS (Experimental Physics and Industrial Control System) to interact with process variables (PVs). It provides tools for retrieving and setting PV values and fetching detailed PV information, and communicates over stdio using the mcp framework.

How to use EPICS-MCP-Server?

Install dependencies with pip install -r requirements.txt. Ensure EPICS is installed locally and an IOC is running with caget, caput, and cainfo working. Use with Langchain by configuring StdioServerParameters with command="python" and the path to the server script.

Key features of EPICS-MCP-Server

• Retrieve the current value of any EPICS PV via get_pv_value
• Set a new value for any EPICS PV via set_pv_value
• Fetch detailed information about any EPICS PV via get_pv_info
• Returns JSON status objects for each operation (success or error)
• Built on the mcp framework for easy integration

Use cases of EPICS-MCP-Server

• Monitoring hardware parameters in accelerator or experimental control systems
• Controlling software or hardware parameters by setting PV values remotely
• Integrating EPICS PV access into AI‑powered workflows via tools like Langchain
