Interview question · Agent, Tool & MCP Security

Beyond a single injected prompt, how do attackers corrupt AI agents through memory, tools, retrieved knowledge and other agents?

Map influence through memory, retrieval, tool metadata, outputs and shared artifacts. Separate persistence from actual impact, govern publication, and recover with explicit coverage of derivatives and ongoing work.

What if · the follow-ups in this answer

The answer works through 4 follow-ups like an interviewer would

A support conversation becomes a proposed fix, then a shared entry. A week later, a reviewer discovers that the fix misstates an important account requirement.

  1. Does the stored entry mean every customer received the wrong answer?
  2. Is deleting the shared entry enough to close the incident?
  3. What if the entry was used to train a released model?
  4. What design supports useful learning with bounded risk?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Premium opens every answer and ladder.
