Features
Agentic MCP Risk Intelligence
MCPSafe checks risks unique to AI-connected MCP servers — prompt surfaces, model-controlled tools, credentials, filesystems, and network reachability.
The current scan did not find prompt-injection, agent command, exfiltration, unbounded filesystem, or MCP SSRF patterns.
Tool metadata can steer or hijack AI clients before a user invokes the tool.
Model-selected tool arguments can reach shell/process execution.
Tool context combines credential access with outbound network capability.
AI-controlled paths may access files outside the intended workspace.
AI-controlled URLs may reach local, metadata, or internal network services.
