Free tool - AI-era only
MCP exposure checker
Most security scanners don't know what MCP is. Vysiro does. Find unauthenticated Model Context Protocol endpoints and leaky llms.txt content on your domain before an AI agent discovers them for you. Free, no signup.
We probe public MCP paths and read your llms.txt from the outside. No signup, nothing installed. Your domain is never stored.
MCP endpoint discovery
Probes common MCP paths (/api/mcp, /.well-known/mcp, /mcp/sse) and reports which respond.
Authentication gap detection
Flags endpoints that respond without an Authorization header - the most common MCP misconfiguration.
llms.txt audit
Reads your llms.txt and surfaces leaks: secret URLs, deprecated routes, or stale claims AI assistants will repeat.
Tool inventory diff
Compares the tool list your MCP server advertises against what's safe to expose.
