agent: mcp

When does this happen?

IF Tool definitions lack safety annotations, causing the LLM to misuse read-only or destructive operations.

How others solved it

THEN Add annotations: `readOnlyHint`, `destructiveHint`, `idempotentHint`, `openWorldHint`. This helps the agent select appropriate tools and avoid unintended side effects.
