UK Legal Research

paulieb89/uk-legal-mcp

Connects Claude and other MCP clients to UK legal sources without API keys. Exposes tools for searching case law from Find Case Law, reading legislation.gov.uk Acts and SIs with point-in-time sections, querying Hansard debates and divisions, tracking bill stages and committee evidence, and parsing OSCOLA citations into canonical references. Also covers HMRC guidance lookups and optional Making Tax Digital endpoints. Returns primary source text plus citation metadata so you can build verifiable evidence packs instead of relying on memory. Runs over HTTP at uk-legal-mcp.fly.dev/mcp or locally via uvx. Most useful when you need to cite UK statutes, trace parliamentary votes, or pull judgment paragraphs with neutral citations for legal research workflows.
