What it does
Legal Skills Open is a repository of plugins with skills for legal work. Each skill is one SKILL.md file holding an algorithm: computing a court fee, analysing a claim under a procedural rule, checking a data processing agreement against GDPR Article 28. Skills sit in country/practice folders, over 410 plugins across 54 jurisdictions. You can clone the repository and use the skills in Claude Code as ordinary plugins. The README describes a second route, the ThomasMore MCP server with discover and invoke tools that finds the right skill itself. The author states that the server launch will be announced on the project site.
Who it is for. Lawyers and compliance specialists using Claude Code or Cursor who want reviewable algorithms instead of one-off prompts.
Good fit when
- You need to check a data processing agreement against GDPR.
- A lawyer drafts a claim and computes the court fee under local rules.
- A team works across several jurisdictions and wants one shared set of analysis rules.
- A developer writes a custom legal skill and looks for a file structure to copy.
Not a fit when
- You need advice someone is accountable for: a skill gives a reference analysis and does not replace a lawyer.
- The task concerns a country outside the repository's 54 jurisdictions.
- A closed network forbids external MCP servers, and a local copy of the repository is too large to keep.
Example request
Check this data processing agreement against GDPR Article 28 and list the missing terms with citations to the provisions.Limitations
The repository is large: the tree holds over 40,000 files, so a full clone takes noticeable space and time. The library is community maintained, each skill has its own version and author, and depth differs between countries. Every skill answer carries a disclaimer that it is information and not legal advice. The ThomasMore MCP server address appears in the README, but at the time of checking the author had only announced its launch. The latest commit is from October 2026.
How to disable. Delete the cloned repository or the individual plugin from the plugin directory and restart the agent. If you connected the MCP server, remove it from the client configuration.
FAQ
How is a skill structured in this library?
It is a SKILL.md file with a YAML header (name, title, description, jurisdiction, practice, version, license) and a body with When to apply, Algorithm and Output contract sections. The schema is in schemas/skill-frontmatter.schema.json.
Is Russian law covered?
Yes, the ru folder holds plugins for arbitration, contracts, intellectual property and litigation.
Do I need the MCP server to use the skills?
No. You can clone the repository and use the skills locally as Claude Code plugins. The ThomasMore MCP server is described as a separate option.
Does the library replace a lawyer?
No. The authors state the answer is informational and works as a second pair of eyes for a professional admitted in the relevant jurisdiction.
How do I add a skill for my country?
Create a folder with the ISO 3166-1 country code, for example pt/contracts/skills/, put a SKILL.md there and open a pull request following CONTRIBUTING.md.
