Configure an MCP-compatible host with this URL:
https://app.briefhq.ai/mcpBrief uses OAuth 2.1-style authorization with PKCE and dynamic client registration. Compatible hosts open sign-in on the first tool call, so there is no API key to create, copy, or rotate.
After connecting, call brief_get_onboarding_context at the start of a product task. Use brief_search for product facts and decision history, and brief_ask for judgment or trade-offs.
Create a self-serve account on the Free plan, which includes a monthly usage allowance and requires no credit card. Brief does not currently publish a separate sandbox environment.

Host-specific instructions are available for Cursor, Claude Code, VS Code, Claude Desktop, Codex, ChatGPT, Windsurf, and other MCP clients.
