Analog Circuit Simulate MCP Server tools

Tool list not available yet

This listing does not currently have a tool list to display. This does not mean the server has no tools; check its documentation for supported capabilities.

We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.

Overview

What is analog-circuit-simulate-mcp-server?

This MCP server provides tools for running analog circuit simulations using ngspice as the simulation backend. It exposes a REST API interface, supports parameterized circuit simulations, and returns results in JSON format. It is intended for users who need to simulate analog circuits within an MCP-enabled environment.

How to use analog-circuit-simulate-mcp-server?

Install ngspice (Linux only), Python 3.8+ and the uv tool. Create a virtual environment with uv venv .venv and activate it. Install dependencies via uv pip install -e .. Start the server with uv run analog-circuit-simulate-mcp-server or via uvx. Add an NPX configuration entry pointing to http://${server_ip}:4044/mcp/. Server ports and JSON response can be configured via the environment variables FASTMCP_PORT (default 4044) and FASTMCP_JSON_RESPONSE.

Key features of analog-circuit-simulate-mcp-server

  • Provides MCP tools for analog circuit simulation
  • REST API interface for simulation control
  • Supports parameterized circuit simulations
  • Returns simulation results in JSON format
  • Backed by the ngspice circuit simulator

Use cases of analog-circuit-simulate-mcp-server

  • Running analog circuit simulations from MCP clients

  • Integrating ngspice simulation into development workflows

Frequently asked questions

1

What are the runtime dependencies?

Python 3.8+, the `uv` package manager, and ngspice installed on the system.

2

How is the server configured?

Server configuration is set via environment variables: `FASTMCP_PORT` (default 4044) and `FASTMCP_JSON_RESPONSE` (set to `True` for JSON output).

3

Where can I find an example circuit file?

The repository includes `high_pass_filter.cir` as an example circuit file for simulation demos.

4

How do I start the server?

Run `uv run analog-circuit-simulate-mcp-server` from the project root, or use `uvx` with the Git repository URL.

5

What transport method is used?

The server provides a REST API on port 4044 at the `/mcp/` endpoint. No authentication mechanisms are mentioned.
