Browser Proof

Browser Proof is an MCP server that enables autonomous agents (such as Claude, Cursor, Windsurf, and other MCP-compatible clients) to verify claims and facts against live public webpages. It extracts supporting evidence text, captures screenshots for auditability, and returns structured JSON responses for downstream automation or decision-making. This tool is ideal for AI assistant developers, compliance teams, or automated research systems that require verifiable evidence from the web, such as checking pricing info, policy language, or listing QA. Integration is possible via MCP endpoints or an HTTP API, with API-key authentication for production use.
