I submitted PR #4646 adding an external tool guide under Advanced, but closed it — it was a product page for an external tool rather than a CrewAI feature guide.

PR fix notes

PR #4674: docs: add security best practices guide for CrewAI agents

Description (problem / solution / changelog)

Summary

  • add a new Advanced docs guide covering CrewAI-native security controls for production agents
  • include guidance for execution bounds (max_rpm, max_iter, max_execution_time), tool least-privilege, delegation risks, output constraints, and human approval gates
  • add the new guide to the English docs navigation

Closes #4651.

Validation

  • uv run python -m json.tool docs/docs.json
  • verified frontmatter and content structure for docs/en/guides/advanced/security-best-practices.mdx
<!-- CURSOR_SUMMARY -->

[!NOTE] Low Risk Low risk documentation-only change that adds a new page and updates navigation; no runtime or API behavior is modified.

Overview Adds a new Advanced guide, security-best-practices.mdx, documenting CrewAI-native security controls for production agents (execution bounds, least-privilege tool access, delegation considerations, structured outputs, and human approval checkpoints).

Updates docs/docs.json to include the new guide in the English Guides → Advanced navigation.

Context

I submitted PR #4646 adding an external tool guide under Advanced, but closed it — it was a product page for an external tool rather than a CrewAI feature guide.

Proposal

Would a security best practices guide be useful in the CrewAI docs? With EU AI Act enforcement starting August 2026, developers building production agents need to think about security patterns. A guide focused on CrewAI-native configuration would cover:

  • Bounding crew execution — setting max_rpm, max_iter, and max_execution_time on Agents to prevent runaway loops
  • Tool access control — restricting which tools each Agent can access, avoiding over-permissioned crews
  • Delegation risks — security considerations when agents delegate to other agents (allow_delegation=True)
  • Input/output validation — using output_pydantic and task expected_output to constrain agent outputs
  • Human oversight — patterns for requiring human approval before high-stakes tool execution

This would be a guide about using CrewAI's own APIs securely, not a product page for external tools. Could mention available static analysis and runtime monitoring options briefly at the end.

Happy to draft this if it fits the docs roadmap.

Fix Plan

To create a security best practices guide for CrewAI, follow these steps:

  • Create a new Markdown file in the documentation repository, e.g., security-best-practices.md
  • Add sections for each of the proposed topics:
    • Bounding crew execution
    • Tool access control
    • Delegation risks
    • Input/output validation
    • Human oversight
  • Include code snippets to illustrate secure configuration, such as:
# Bounding crew execution
agent = CrewAI(
    max_rpm=100,
    max_iter=1000,
    max_execution_time=300  # 5 minutes
)

# Tool access control
agent.restrict_tools(['tool1', 'tool2'])

# Input/output validation
from pydantic import BaseModel

class ExpectedOutput(BaseModel):
    result: str

task = CrewAI.task(expected_output=ExpectedOutput)
  • Briefly mention available static analysis and runtime monitoring options at the end of the guide

Verification

To verify the guide is effective, review it for completeness and accuracy, and test the code snippets to ensure they work as expected.

Extra Tips

  • Consider adding examples of common security pitfalls and how to avoid them
  • Provide links to relevant CrewAI documentation and external resources for further reading
  • Review and update the guide regularly to reflect changes in CrewAI's APIs and security best practices
