Risk Summary

Needs Approval

Excessive Permissions plus Dep Visibility raises enough risk that this tool should not be auto-trusted.

Potential impact: The agent may gain overly broad access to files, network, databases, or execution capabilities.

Recommended action: Keep this tool behind manual approval and avoid unattended runs until the risky capabilities are narrowed or removed.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

Security Findings (29)

  • HighAS-002

    ⚠️Excessive Permissions ×7

    tool declares network permission

    brave_web_searchbrave_news_searchbrave_image_searchbrave_video_searchbrave_local_searchbrave_llm_contextbrave_place_search

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • HighAS-010

    🔑Insecure Secret Handling ×2

    input parameter "maximum_number_of_tokens" appears to accept a secret or credential

    brave_llm_context

    input parameter "maximum_number_of_tokens_per_url" appears to accept a secret or credential

    brave_llm_context

    Fix: Avoid accepting raw credentials as input parameters. Use secret managers (e.g. 1Password CLI, AWS Secrets Manager) and ensure credentials are never logged or stored in agent traces.

  • MediumAS-002

    ⚠️Excessive Permissions ×2

    tool declares db permission

    brave_local_searchbrave_place_search

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • LowAS-002

    ⚠️Excessive Permissions ×3

    input schema exposes 15 properties (threshold: 10)

    brave_web_search

    input schema exposes 14 properties (threshold: 10)

    brave_llm_context

    input schema exposes 13 properties (threshold: 10)

    brave_place_search

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×7

    tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

    brave_web_searchbrave_news_searchbrave_image_searchbrave_video_searchbrave_local_searchbrave_llm_contextbrave_place_search

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×8

    Tool did not expose metadata.dependencies or repo_url, so supply-chain coverage is limited.

    brave_web_searchbrave_news_searchbrave_image_searchbrave_video_searchbrave_local_searchbrave_llm_contextbrave_place_searchbrave_summarizer

    Fix: Review and remediate the identified issue.

Scan this tool yourself
