CourtListener MCP (Official)
Free Law Project's official MCP server — search millions of court opinions, dockets, and judges from your AI assistant.
The official hosted MCP server from Free Law Project, the nonprofit behind CourtListener. Connects an AI assistant directly to one of the largest free collections of American case law: roughly ten million opinions (including the merged Caselaw Access Project corpus), PACER/RECAP dockets, citation networks with citation verification, oral argument recordings, and judge biographies and financial disclosures. Supports keyword and semantic search plus real-time alerts. Sign-in uses OAuth with a free CourtListener account, and API throughput follows your account tier — free accounts have daily limits, paid Free Law Project memberships raise them. Launched May 2026. Being first-party, it tracks CourtListener's API as it evolves.
