Reference

mcltspice exposes 42 tools, 6 resources, and 8 prompts. This section documents every one of them with parameter types, defaults, return values, and usage notes.

Tools by category

Simulation (7 tools) Run schematics and netlists, sweep parameters, vary temperature, run Monte Carlo analysis, optimize and tune component values.

Waveform (5 tools) Extract signals from .raw files, evaluate math expressions, export data to CSV, and generate SVG Bode and time-domain plots.

Signal Analysis (4 tools) FFT, THD, bandwidth measurement, operating point extraction, and transfer function queries.

Noise (3 tools) Full noise spectral density analysis, spot noise at a frequency, and integrated RMS noise over a band.

Stability and Power (3 tools) Gain and phase margin from loop gain data, power dissipation metrics, and efficiency calculations.

Schematic and Netlist (8 tools) Read, edit, diff, and DRC schematics. Build netlists programmatically, generate from templates, parse Touchstone files.

Library and Templates (7 tools) Browse 6500+ symbols, 4000+ example circuits, search SPICE models and subcircuits, list templates, verify installation.

SpiceBook (5 tools) Publish circuits as interactive notebooks on SpiceBook, run remote ngspice simulations, list and manage published notebooks.

Resources and prompts

Resources (6 URIs) Read-only data sources exposed via MCP resource URIs --- symbols, examples, status, templates, template detail, and SpiceBook status.

Prompts (8 prompts) Guided workflows for filter design, power supply analysis, debugging, optimization, Monte Carlo, circuit creation, troubleshooting, and SpiceBook publishing.
