Sentinel vs MCP Server
A side-by-side look at the Sentinel and MCP Server MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
MCP ServerMonitoring · Local subprocess (stdio)Website monitoring that catches pages that look broken even when the site is up (uptime, performance, SSL, DNS, visual regression, content change). 17 tools: DNS lookup, SSL inspection, speed test, website check and service health work without an account; monitor, incident, alert, status-page and server tools need a Visual Sentinel API key (Business and Agency plans). Published as @visualsentinel/mcp-server on npm.57GoodAuth: api key requiredVerdict: choose Sentinel for monitoring work over a hosted endpoint; choose MCP Server for monitoring as a local process. You can also run both side by side in one mcpServers block.
