# Court Rules

> Court Rules is a free reference for U.S. federal and state court rules: local rules, individual judge standing orders, court holidays and a filing-deadline calculator, with a public API and a remote MCP server. Every rule links back to its source order.

Court Rules reads each judge's order, pulls out the requirements that affect a filing (page limits, courtesy copies, pre-motion letters, AI disclosure, hearing procedures), keeps every version and flags real changes. Coverage is over 600 federal judges' standing orders across 20 federal districts, plus a state-court beta. Read the order itself before relying on a summary.
