# OWASP ASI02 — Tool Misuse & Exploitation

OWASP ASI02 — Tool Misuse & Exploitation: what it does, its label on each agent, what it misses, and examples.

Catalog policy owasp-asi02-tool-misuse, version 0.0.2, labelled advisory on Claude Code.

> Ask the user before running any command on this page: each one changes how their agent or repository behaves.

## What it does

Constrain what an agent's legitimate tools can be made to do. Grant least agency per task, validate tool parameters at the runtime boundary, authorise every invocation rather than only the first, and distrust tool metadata from unverified registries. Use when defining tool schemas, wiring an MCP server, granting shell or cloud-CLI access, or reviewing a tool-calling loop. Do NOT use for the credentials the tool authenticates with — that is \`owasp-asi03-identity-privilege-abuse\`.
