Gaff Check

Overview

Gaff Check is a Model Context Protocol server that brings Irish property due diligence directly into your AI assistant. It surfaces planning history, property prices, flood risk, radon levels, zoning information, Building Energy Rating data, and crime context for any address—all the research you'd normally do across multiple websites, now callable as tools.

The server runs locally on your machine via npx -y gaff-check. It's built on the gaff-check npm package at v0.2.0 and requires no credentials or external authentication to operate. The source code lives at iarfhlaith/gaff-check on GitHub.

Gaff Check is listed in the Development category on mcp.site and works with any MCP client, including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. Maintainers from iarfhlaith are invited to claim this listing to verify ownership and keep information up to date.
