ibkr-portfolio-builder-mcp vs ltspice-mcp

ibkr-portfolio-builder-mcp: This is a remote MCP server designed for top-down portfolio construction using Interactive Brokers, specifically built to integrate with LLMs like Claude.ai. It provides a rich research vocabulary including a typed scan catalog and market data, enabling LLMs to perform sophisticated financial analysis and strategy generation.; 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.

Features

ibkr-portfolio-builder-mcp logoibkr-portfolio-builder-mcp
01Typed Scan Catalog with 468 IBKR scan codes across 16 categories and 28 strategy tags.
02Inverse Pair Links for easy strategy polarity flipping (e.g., HIGH_X ↔ LOW_X).
03Per-scan Instrument Map indicating applicable instrument types (STK, ETF, OPT, BOND).
04News and Screeners integrated into a single tool surface for contextual analysis.
05Two authentication modes: OAuth 2.1 for Claude.ai and static bearer token for other clients.

01Simulation 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.
