Numguard

Numguard is a local MCP server that checks a number before an agent states it, covering evals, backtests with Deflated Sharpe, and signed receipts.

What you can do

• Verify a numeric claim before an assistant asserts it.
• Run evaluation checks on reported figures.
• Assess backtest results, including a Deflated Sharpe measure.
• Produce signed receipts for the verification outcome.
• No tool list is published, so exact operations are not documented.

When to use it

Worth adding when an assistant reports metrics, evaluation scores or backtest performance and you want those numbers checked rather than taken at face value, especially where a signed record of the check matters.

Requirements

Runs as a local process on the user's machine, installed from the numguard package on PyPI and started with Python. Desktop only; no web execution. No authentication, environment variables or headers are declared.
