Where possible, screen proposed tool calls against the **original user intent** in a `PRE_TOOL_CALL` hook — without re-feeding the untrusted intermediate content that may have caused drift.

- Email/ticket/CRM ingestion
- Knowledge bases that accept untrusted uploads
- MCP servers that return arbitrary remote content
### Mitigations
- Prefer summaries and structured extracts over raw HTML/Markdown in context when possible.
- Separate **research agents** (read untrusted content, no side-effect tools) from **action agents** (send email, write files, call APIs).
- Hand off only **validated structured state** between them — not raw tool dumps. If both agents share one crew transcript without a gated handoff, untrusted text can re-enter the actor's context.
- Run guardrails on research outputs before an action agent sees them.
- Validate URLs and destinations in tool hooks (domain allowlists; block link-local/private ranges where appropriate to reduce SSRF risk).

Still better for high-risk sends: put research and send in **separate flow steps** (see [Isolation](#8-isolation-between-agents)) and add a tool-hook allowlist plus approval gate on `send_email`.
Prefer separate flow steps for research vs send so the sender never sees raw scraped content.
## 4. Tool abuse
Tool abuse is what happens when a steered agent uses legitimate tools in harmful ways: deleting data, exporting records, spending money, sending messages, or executing code.
### Principle of least privilege
Tool abuse is when a steered agent uses legitimate tools in harmful ways: deleting data, exporting records, spending money, sending messages, or executing code.
- Give each agent the **minimum tool set** for its role.
- Prefer read-only tools for research agents.
- Put irreversible operations behind separate tools with stricter controls.
- Constrain tool arguments in code (paths, SQL, URLs, recipients) — do not rely on the model to "be careful."
- Prefer short-lived, per-tool credentials over one shared high-privilege service account.

### Patterns in CrewAI
1. **Tool-level approval** — block until an operator confirms:
```python
from crewai.hooks import HookAborted, InterceptionPoint, ToolCallHookContext, on
from crewai.hooks import HookAborted, InterceptionPoint, on
@on(InterceptionPoint.PRE_TOOL_CALL, tools=["send_email"])
def require_email_approval(ctx: ToolCallHookContext) -> None:
def require_email_approval(ctx):
response = ctx.request_human_input(
prompt=f"Approve {ctx.tool_name}?",
default_message=(
f"Tool: {ctx.tool_name}\n"
f"Args: {ctx.tool_input}\n"
"Type 'yes' to approve:"
),
default_message=f"Args: {ctx.tool_input}\nType 'yes' to approve:",
)
if response.lower() != "yes":
raise HookAborted(reason="denied by operator", source="approval-gate")
```
Show reviewers the tool name, arguments, and enough context to judge drift from the user's original request — avoid rubber-stamp prompts.
2. **Task-level human input** — set `human_input=True` when a task result must be reviewed before the crew continues:
```python
from crewai import Task
review_task = Task(
description="Draft the outreach email for {topic} using the research notes.",
expected_output="A ready-to-send email draft for reviewer approval",
agent=sender, # action agent from your crew
context=[research_task],
human_input=True,
)
```
See [Human Input on Execution](/en/learn/human-input-on-execution).
3. **Flow-level review** — use `@human_feedback` or Enterprise HITL webhooks for production review queues. See [Human-in-the-Loop](/en/learn/human-in-the-loop) and [Human Feedback in Flows](/en/learn/human-feedback-in-flows).
Other patterns: `human_input=True` on a [Task](/en/learn/human-input-on-execution), or `@human_feedback` / Enterprise HITL webhooks ([Human-in-the-Loop](/en/learn/human-in-the-loop), [Human Feedback in Flows](/en/learn/human-feedback-in-flows)).
<Tip>
Default HITL helpers are often **blocking console** prompts. For production, wire a non-blocking provider or Enterprise webhooks so approvals land in Slack/Teams/your review queue instead of stdin.

## 7. Limiting delegation
Delegation multiplies blast radius: a compromised or confused agent can enlist others with broader tools or access.
Delegation multiplies blast radius.
### Defaults
- Keep `allow_delegation=False` unless collaboration is required (this is the Agent default).
- If you enable delegation, restrict which agents exist in the crew and which tools each one has. There is no separate "delegate only to agent X" ACL — membership and per-agent tools are the boundary.
- Prefer explicit task graphs (sequential processes you design) over open-ended delegation for high-risk workflows.
- In a **hierarchical** process, managers are set up to delegate. Keep high-risk tools on specialists behind hooks and approvals — not on every worker, and not on the manager unless required.
- Treat remote/A2A delegation as a separate security domain. Prefer `A2AClientConfig`, leave `trust_remote_completion_status=False` unless you intentionally trust remote completion, and validate returned content before acting on it. See [A2A Agent Delegation](/en/learn/a2a-agent-delegation).

### Practical isolation patterns
1. **Split read and write privileges** across agents (researcher vs actor).
2. **Separate crews or flow steps** for untrusted ingestion vs privileged action.
3. **Pass validated structured state** between steps, not raw tool dumps.
4. **Scope knowledge** with per-agent `knowledge_sources` when corpora differ in sensitivity. For memory: give an agent its own `Memory` / `MemoryScope`, or disable memory on the **crew** — setting `memory=False` on an agent alone does **not** isolate it if the crew has memory (the agent falls back to crew memory).
5. **Sandbox code execution** with [E2B tools](/en/tools/ai-ml/e2bsandboxtools) (or another external sandbox you integrate) — never run model-generated code on the host. Treat sandbox output as untrusted. Built-in `CodeInterpreterTool` / `allow_code_execution` are removed/deprecated.
6. **Isolate MCP and third-party tool servers** — only connect to servers you trust; prefer least-privilege credentials per server. See [MCP Security](/en/mcp/security).
