analog_circuit_simulate_mcp_server by abelzhao - MCP Server

analog-circuit-simulate-mcp-server

A Model Context Protocol (MCP) server for analog circuit simulation

Features

Provides MCP tools for running analog circuit simulations
REST API interface for simulation control
Supports parameterized circuit simulations
Returns simulation results in JSON format

Installation Guide (Linux only)

Install ngspice (required for simulation backend):

sudo apt-get install ngspice  # For Debian/Ubuntu systems

Ensure Python 3.8+ is installed (see .python-version file) and install uv tool:
```
pip install uv
```

Create and activate virtual environment:

uv venv .venv
source .venv/bin/activate  # Linux/macOS

Install dependencies using different methods:

Direct installation with uv:
```
uv pip install -e .
```

Build with uv then install:

uv build && pip install dist/analog_circuit_simulate_mcp_server-${version}-py3-none-any.whl
# or uv build && pip install dist/analog_circuit_simulate_mcp_server-${version}.tar.gz

Traditional pip installation:
```
pip install -e .
```

Usage

Starting the Server

Different ways to run the server:

Using uv run:

uv run analog-circuit-simulate-mcp-server

Using uvx (requires uvx installation):

uvx --from https://github.com/abelzhao/analog_circuit_simulate_mcp_server.git analog-circuit-simulate-mcp-server
