ltspice-mcp vs python-sdk
ltspice-mcp: This project provides an MCP server that bridges LLM assistants with powerful circuit simulators like LTspice and ngspice, along with direct editing capabilities for LTspice schematics. It allows AI assistants to design, verify, and iterate on circuits by interpreting simulation results as structured data and interacting with circuit files directly, avoiding manual rawfile parsing.; python-sdk: The MCP Python SDK provides a robust implementation of the Model Context Protocol, enabling developers to build secure, standardized servers that expose data and functionality to LLM applications. It also includes a client library for connecting to any MCP server, supporting various standard transports like stdio, Streamable HTTP, and SSE.

TL;DR
ltspice-mcpAPI Integration · ★ 65
Automated circuit biasing and characterization: Automatically bias an NMOS stage into saturation, or characterize device parameters like gm/ID versus VGS.
python-sdkAPI Integration · ★ 24.6k
When to choose:
- You want the official, MIT-licensed reference Python SDK maintained directly by the Model Context Protocol project.
- You need full low-level control over MCP primitives (resources, prompts, tools, sampling) and standard transports (stdio, SSE, Streamable HTTP).
When to skip:
- You want higher-level conveniences like automatic client composition or less decorator boilerplate; FastMCP wraps the protocol with extra ergonomics.
- You are exposing an existing GraphQL or FastAPI backend where a gateway or adapter (Grafbase or FastAPI-MCP) requires no manual tool code.

Features
ltspice-mcp01Simulation and structured measurement results: Runs LTspice/ngspice, parses binary output directly, and returns precise measurements (e.g., cutoff frequencies, operating points, stability margins) as structured numbers.
02Schematic and netlist editing: Supports creation and modification of LTspice `.asc` schematics and SPICE `.cir`/`.net` netlists with built-in validation.
03Advanced analysis capabilities: Enables multi-dimensional parameter sweeps and Monte Carlo simulations with component tolerances and process variations.
04Robust job management: Simulations run as cancellable jobs with timeouts and concurrency limits, and results report facts with simulator warnings for agent interpretation.
05Co-design workflow: Facilitates iterative design by allowing assistants and human users to collaboratively edit and verify circuits using standard LTspice and SPICE files.
python-sdk01Build MCP servers to expose tools, resources, and prompts to LLM applications.
02Develop MCP clients to connect to and interact with any MCP server.
03Support for standard transports: stdio, Streamable HTTP, and SSE.
04Simplified server development with Python type hints for schema definition, eliminating manual JSON Schema and validation.
