FAQ

Questions

How do I install Spicebridge?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Spicebridge need an API key?

No required environment variable is listed on this record.

What transport does Spicebridge use?

Spicebridge runs locally over stdio.

Documentation

SPICEBridge

AI-powered circuit design through simulation — an MCP server that gives language models direct access to SPICE circuit simulation via ngspice. Describe a circuit in plain English and let the AI handle netlist generation, simulation, measurement, and spec verification.

Features

28 tools covering the full circuit design workflow
11 built-in templates with automatic component value calculation (E24 series)
Simulation: AC sweep, transient, DC operating point
Measurement: bandwidth, gain, DC levels, transient metrics, power
Monte Carlo & worst-case analysis under component tolerances
Multi-stage composition — connect circuit stages with automatic port mapping
Model wizard — generate SPICE .lib models from datasheet parameters
KiCad export — output .kicad_sch schematics
Web viewer — interactive schematic viewer in the browser
Cloud setup wizard — one-command deployment with Cloudflare tunnels (spicebridge setup-cloud)
Spec verification — compare results against design targets

Install

pip install spicebridge

Requirements

Python 3.10+
ngspice installed and on PATH

Quick Start

Local (Claude Code / stdio)

Add to your .mcp.json:

{
  "mcpServers": {
    "spicebridge": {
      "command": "spicebridge"
    }
  }
}

Cloud (Streamable HTTP)

spicebridge --transport streamable-http --port 8000

Cloud Setup Wizard

One command to go from a local install to a public MCP endpoint:

spicebridge setup-cloud          # interactive (named tunnel, permanent URL)
spicebridge setup-cloud --quick  # quick tunnel (temporary URL, no account needed)

The wizard handles the full deployment pipeline:

Installs cloudflared automatically (macOS via Homebrew, Linux via APT) if not found
Authenticates with Cloudflare (browser-based OAuth, named tunnel mode only)
Creates or reuses a tunnel — prompts to pick an existing one or make a new one
Configures DNS routing for your custom domain (named tunnel mode)
Generates an API key for authentication
Starts the SPICEBridge server and tunnel together
Prints connection info with a ready-to-paste JSON config for Claude.ai

Quick tunnels give you a temporary trycloudflare.com URL instantly — no Cloudflare account required. Named tunnels give you a permanent custom domain (e.g. spicebridge.example.com).

Additional options:

spicebridge setup-cloud --domain mcp.example.com  # specify custom domain
spicebridge setup-cloud --port 9000                # custom port
spicebridge setup-cloud --no-install               # skip cloudflared installation

Example

1. load_template("rc_lowpass_1st", specs={"f_3dB_hz": 1000})
   -> netlist with R=1.6k, C=100nF, circuit_id: "a1b2c3d4"

2. run_ac_analysis(circuit_id, start_freq=1, stop_freq=1e6)
   -> frequency response data

3. measure_bandwidth(circuit_id)
   -> f_3dB_hz: 995

4. compare_specs(circuit_id, specs={"f_3dB_hz": {"target": 1000, "tolerance_pct": 5}})
   -> PASS

5. draw_schematic(circuit_id)
   -> schematic SVG
