Umowy.AI MCP Server

An official MCP server by Umowy.AI that connects AI models to the Polish Dziennik Ustaw (Journal of Laws). It allows agents to retrieve full text of statutes, check daily in-force status, and verify legal provisions by date, ensuring responses are based on current law rather than model memory.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http umowy-ai-mcp-server https://mcp.umowy.ai/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add umowy-ai-mcp-server --url https://mcp.umowy.ai/mcp

Cursor
