PreClick — An MCP-native URL preflight scanning service for autonomous agents (formerly URLCheck).
PreClick sits between your AI agent and the open web, scanning URLs for phishing, malware, and intent mismatches before navigation happens. It exposes two main tools via MCP: url_scanner_scan for basic threat analysis and url_scanner_scan_with_intent when you want to verify a link actually matches what your agent is trying to do (like confirming a booking URL is really for hotels, not a lookalike). The hosted endpoint at preclick.ai/mcp runs stateless over streamable-http with a 100 request daily trial, no key required. For tighter integration there are standalone Python and Node clients that handle the async polling without touching MCP protocol details. Reach for this when your agent browses autonomously and you need a security gate that understands context, not just pattern matching.

Install
From registry metadata$ npx add-mcp https://urlcheck.ai/mcp --name urlcheck-mcp --header 'X-API-Key: ${X_API_KEY}'Run in your terminal. add-mcp asks which agents to add it to, then asks for each value it needs. Add -g to install it for every project.
Review the command, arguments and environment values before installing. MCP servers run with your local permissions.
Other ways
Claude Code
$ claude mcp add --transport http urlcheck-mcp https://urlcheck.ai/mcp --header 'X-API-Key: YOUR_X_API_KEY'Run in your terminal. Add --scope user to make it available in every project.
