Frequently Asked Questions
What are MCP tool permission attacks?
They abuse MCP servers or tools that have more access than needed, letting an attacker trick an agent into reading files, calling APIs or taking actions outside its intended purpose.
How can MCP servers be secured?
Apply least privilege, scope tool permissions narrowly, validate inputs, require approval for sensitive actions and monitor tool calls. Treat tool descriptions and outputs as untrusted data.
Is there a free MCP security course?
Yes. This advanced room on Codelivly is free and hands-on. You practice exploiting misconfigured permissions and over-privileged servers in a safe lab, then learn how to defend against them.
