AI that knows what it doesn't know

Two legs to the catalogue. Skills are ready-made abilities you run locally - a content reviewer, GDPR anonymisation, a devil's advocate, EU law and CJEU search. MCP connectors feed the agent live sources of law - Europe, the Americas, Asia-Pacific - each with a stable identifier and a link back to the source. Pick the room you want to enter.

We count downward: there are more in reality.

How it works

Two paths, both without a terminal

Skills and connectors install with one command, right inside Claude or PATRON - no terminal, no Git. Prefer clicking? A skill also loads via a simple wizard. The rest happens locally.

Skills - one commandAdd the marketplace and install a whole bundle with one command in Claude Code or PATRON. Prefer not to? The MateMatic installer for Windows places the skill itself - no Git, no configuration.
Connectors - one command or one configPlug in the MCP server with uvx/npx, or paste a ready-made block into PATRON or Claude.
Use it on your own documents, locallySkill and connector are available right away - your data stays with you.

Skills and connectors support a lawyer's work; they don't replace their judgement. MateMatic's reading of the GDPR and the AI Act, not the position of any bar or chamber.
