API access

Get a free API key

One key for the REST API and the hosted MCP server — the whole structured MPEP, machine-side. Free tier is 60 requests a minute and 5,000 a day. Confirm your email and we’ll reveal your key.

Have a PatentReply account? You don’t need a key for MCP: add https://api.mpep.io/mcp to Claude, Cursor or any MCP client and sign in when prompted. Keys are for scripts, CI and REST calls without an account.
