mcp-vcd

What is this MCP

This is a Model Context Protocol (MCP) server designed specifically for working with Value Change Dump (VCD) waveform files. It helps manage large waveform data that wouldn't otherwise fit in a model's context window.

How to use this MCP

Install using uv pip install --system mcp-vcd and configure in your claude_desktop_config.json. The main tool get-signal allows you to extract specific signal changes from VCD files, with optional timestamp filtering.

What this MCP can be used for

This MCP is particularly useful for hardware engineers and developers working with digital waveforms, enabling selective analysis of signal changes without overwhelming the model's context window with entire VCD files.
