What is the Leakguard MCP server?

Connect Leakguard to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Static analyzer flagging lookahead bias & data leakage in ML/trading code before backtest. The leakguard mcp server is what makes that connection.

What the server does

Works for any time-series ML code — quant trading (crypto, equities, forex, futures), demand forecasting, energy, weather, IoT sensors — wherever a wrong .shift() or a global normalization silently poisons your results.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • Requirements — The Requirements tool exposed by this server

Credentials and setup notes

  • Python 3.11+ - uv (recommended) or pip

Installation

Installation goes through your MCP client rather than a global install: point it at leakguard-mcp on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Where it fits

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Leakguard's toolset — Requirements — is a fair guide to whether it matches your workflow. It is maintained by doazvjettu; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Leakguard's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Leakguard to MCP-compatible AI assistants such as Claude and Cursor, exposing 1 tool (Requirements) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Leakguard directly.
