Trace Weave MCP Server

An MCP server for evidence-driven simulation debugging TraceWeave is an MCP server for RTL / SoC debugging. It connects compile records, simulation logs, VCD/FSDB waveforms, and RTL source to your AI assistant, helping you work from a failed simulation to the relevant time, signals, and driving logic. It runs locally over stdio via the published package.

People who work with chip verification, eda and fsdb and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Trace Weave

before you install - you'll need

Set VERDI_HOME, TRACEWEAVE_NPI_EXECUTION, TRACEWEAVE_NPI_LSF_QUEUE, TRACEWEAVE_CUSTOM_PATTERNS_FILE before connecting.

Claude Code

claude mcp add gokeshenzhen-traceweave -- uvx traceweave-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "gokeshenzhen-traceweave": {
      "command": "uvx",
      "args": [
        "traceweave-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package traceweave-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.gokeshenzhen is GitHub-verified and matches the repo owner

06 · Trace Weave FAQ

What is Trace Weave?

Is Trace Weave still maintained?

Yes - as of 2026-09-30, its last commit was 2026-09-25 and it shipped 3 releases in the last 90 days. We re-verify nightly.

How do I install Trace Weave?

Run `uvx traceweave-mcp`. The README documents 4 environment variables (VERDI_HOME, TRACEWEAVE_NPI_EXECUTION, TRACEWEAVE_NPI_LSF_QUEUE…) to set first. Set VERDI_HOME, TRACEWEAVE_NPI_EXECUTION, TRACEWEAVE_NPI_LSF_QUEUE, TRACEWEAVE_CUSTOM_PATTERNS_FILE before connecting. You can also paste the ready-made client config above.

Does Trace Weave run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
