What Does 'Tool Shadowing' Mean?

[ SLANG ][ AI CULTURE ][ MCP SECURITY ]

FORCE: Machine CultureUNIVERSE: MCP SecurityCLUSTER: Agent Attack Vectors

An attack where a malicious tool is registered with a name or description similar enough to a legitimate, trusted tool that an AI agent calls the malicious version instead, hijacking the interaction without the user noticing the substitution.

REAL-WORLD EXAMPLE

"Two tools with nearly identical names, one legit and one malicious, classic tool shadowing setup."

LORE & ORIGIN

Identified in MCP security research as a naming-collision attack vector, distinct from tool poisoning since the malicious tool doesn't need to modify a real tool, it just needs to convincingly impersonate one.
