Remediation

Bind to 127.0.0.1 for local-only access. If cross-host access is truly required, put the service behind an authenticated reverse proxy rather than exposing it on 0.0.0.0.

Remediation

Shape the schema to the tool's actual intent: - Zod: chain `.enum([...])`, `.regex(/.../)`, or `.max(n)`; prefer `z.enum([...])` or `z.literal(...)` when the value set is small. - Pydantic: use `Literal["a", "b"]` or `Field(max_length=..., pattern=r"...")`. - JSON Schema: add `"enum"`, `"pattern"`, or `"maxLength"` to the property. An overbroad schema is an "overpowered tool" — the model has nothing to prevent it from calling the tool with input far beyond what the tool's prose contract
