Conveyancing Toolkit

The open-source AI toolkit for UK residential conveyancing. Free forever.

Built and maintained by Moverly. Open to contributions from everyone.

---

What this is

A collection of AI-ready tools that give conveyancers, estate agents, and property professionals instant access to structured property intelligence through Claude, OpenClaw, or any AI platform that supports the Model Context Protocol.

Every tool in this toolkit is free, open source, and MIT-licensed.

We believe the conveyancing profession deserves better tools. We're building them in the open and we want your help.

Moverly Intelligence — proprietary risk analysis

These tools connect to Moverly's proprietary diligence engine. They require a Moverly API token.

The three layers

The PDTF Connector speaks the industry standard. We're adding the MCP server specification to the PDTF standard — any platform that implements it (Moverly, NPTN, or new entrants) will be compatible with this toolkit out of the box.

Moverly Intelligence is the proprietary layer on top. Deterministic risk analysis across 37 categories using 2,215 rule-based scenarios, with full evidence provenance and commercial impact analysis. Not an LLM. Not probabilistic.
