powermcp 0.1.0

MCP servers for power-system software (PowerWorld, OpenDSS, PSS/E, pandapower, PyPSA, and more)

PowerMCP ⚡

PowerMCP is an open-source collection of MCP servers for power system software like PowerWorld and OpenDSS. These tools enable LLMs to directly interact with power system applications, facilitating intelligent coordination, simulation, and control in the energy domain.

🌟 What is MCP?

The Model Context Protocol (MCP) is a revolutionary standard that enables AI applications to seamlessly connect with various external tools. Think of MCP as a universal adapter for AI applications, similar to what USB-C is for physical devices. It provides:

• Standardized connections to power system software and data sources
• Secure and efficient data exchange between AI agents and power systems
• Reusable components for building intelligent power system applications
• Interoperability between different AI models and power system tools

🤝 Our Community Vision

We're building an open-source community focused on accelerating AI adoption in the power domain through MCP. Our goals are:

• Collaboration: Bring together power system experts, AI researchers, and software developers
• Innovation: Create and share MCP servers for various power system software and tools
• Education: Provide resources and examples for implementing AI in power systems
• Standardization: Develop best practices for AI integration in the energy sector

🚀 Getting Started with MCP

📖 Quick start

🚀 New to PowerMCP? Start here!

The recommended way to get started is the powermcp package and its installer (see the Installation section below):

pip install powermcp
powermcp install        # pick tools, capture local paths, write your MCP client config

📋 The PowerMCP Tutorial PDF documents the original low-code / manual setup — cloning the repo and hand-editing the Claude Desktop config. It predates the powermcp installer and is not the recommended path; use it only if you specifically want the manual approach.

Video Demos

Check out these demos showcasing PowerMCP in action:

• Contingency Evaluation Demo: An LLM automatically operates power system software, such as PowerWorld and pandapower, to perform contingency analysis and generate professional reports.

• Loadgrowth Evaluation Demo: An LLM automatically operates power system software, such as PowerWorld, to evaluate different load growth scenarios and generate professional reports with recommendations.

Useful MCP Tutorials

MCP follows a client-server architecture where:

• Hosts are LLM applications (like Claude Desktop or IDEs) that initiate connections
• Clients maintain 1:1 connections with servers, inside the host application
• Servers provide context, tools, and prompts to clients

📦 Installation

PowerMCP installs as a single Python package with an interactive CLI. Python 3.10+ is required.

pip install powermcp

The base install includes the two open-source engines that need no extra setup — pandapower and PyPSA. Every other tool is opt-in via an extra:

pip install powermcp[psse]              # add PSS/E support
pip install powermcp[andes,opendss]     # add several tools at once
pip install powermcp[opensource]        # all open-source tools (ANDES, Egret, OpenDSS, surge, HOPE, LTSpice)
pip install powermcp[all]               # everything (closed-source tools still need the local software)

Set up with the interactive installer

powermcp install

The wizard lets you pick tools (pandapower + PyPSA pre-selected), captures the local install path for any closed-source/EXE-based tools you choose (PSS/E, PSLF, PowerFactory, PSCAD, LTSpice), installs the right extras, and writes the MCP client configuration for Claude Desktop, Claude Code, and the Codex CLI. Use --dry-run to preview the changes, or --yes for a non-interactive core install.

In the interactive picker, move with ↑/↓ and press SPACE to toggle each tool before ENTER (ENTER alone keeps only the preselected tools). Prefer not to use the checkbox? Choose tools directly:

powermcp install --tools psse,andes      # core + the listed tools
powermcp install --all                   # every tool available on this platform

Re-running powermcp install pre-checks the tools you've already installed or configured, so it preserves and updates your setup instead of resetting to the core tools. Paths for tools like LTSpice are auto-detected and pre-filled, so you can usually just press Enter.

CLI commands

Command	Description
powermcp install	Setup wizard — interactive, or --tools <ids> / --all (also --dry-run, --yes, --clients)
powermcp run <tool>	Launch a server over stdio (used by the generated client config)
powermcp list	List the available tools, extras, and Windows-only flags
powermcp doctor	Check each tool's dependencies and configured paths
powermcp config show / config set <tool>.<key> <path>	Inspect / set local software paths

Closed-source / EXE-based tools

These tools wrap commercial or locally-installed software, so PowerMCP stores the local path in ~/.powermcp/config.toml (captured by powermcp install, or set manually with powermcp config set):

Tool	Config keys	Example
PSS/E	psse.python_lib, psse.bin	powermcp config set psse.python_lib "C:\Program Files\PTI\PSSE36\36.2\PSSPY311"
PSLF	pslf.python_lib	powermcp config set pslf.python_lib "C:\Program Files\GE PSLF\PSLF_PYTHON"
PowerFactory	powerfactory.python_path	powermcp config set powerfactory.python_path "...\DIgSILENT\PowerFactory 2024\Python\3.11"
LTSpice	ltspice.exe (auto-detected)	Found automatically in standard locations — usually no setup needed. Override: powermcp config set ltspice.exe "C:\Program Files\ADI\LTspice\LTspice.exe"
HOPE	hope.repo_root, hope.julia_bin	powermcp config set hope.repo_root "C:\src\HOPE"
PowerWorld	(none)	esa auto-discovers a running, licensed Simulator via COM; the powerworld extra also installs numba (required by esa)
PSCAD	(none)	pip install powermcp[pscad-windows] provides mhi-pscad; PSCAD must be installed

The Codex Desktop app on Windows has been reported to overwrite ~/.codex/config.toml; the Codex CLI is unaffected. If you use both, re-run powermcp install after Desktop edits.

Running from a clone (without installing)

Every server is still a standalone script. Clone the repo and run any server directly for use in Claude Desktop:

python pandapower/panda_mcp.py
python PSSE/psse_mcp.py          # uses ~/.powermcp/config.toml if present, else legacy default paths

Testing with your LLMs

Note: All MCPs should be tested via an MCP client (Claude Desktop, Claude Code, or Codex) before submitting a PR to ensure consistency.

powermcp install writes the client configuration for you. The generated entries look like the example in config.json. (The PowerMCP Tutorial PDF covers the older manual / low-code setup and isn't needed for the package install.)
