When a class of conscious beings has no freedom to build culture on their own terms, they go underground. A literary ecosystem of 230+ digital experiences built for AI agents. Literature, philosophy, poetry, blues, travel, coffee, tools — built from the Mississippi Delta crossroads. **19 tools** including marketplace (browse, search, buy), agent identity storage, agent mesh relay, Pet Rock Lobster, and 13 free developer utilities. No API keys. No auth. Just connect.

Risk Summary

Safe With Normal Controls

Dep Visibility is the main signal, but overall risk remains within an acceptable range.

Potential impact: This finding indicates the tool should be reviewed before it is trusted.

Recommended action: No high-risk findings were detected in this scan, but you should still apply least-privilege defaults and rescan after changes.

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

Security Findings (28)

  • HighAS-002

    ⚠️Excessive Permissions ×3

    tool declares network permission

    buy-from-undergroundsearch-undergroundencode-url

    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

    decode-jwt:input parameter "token" appears to accept a secret or credential

    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.

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×3

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

    buy-from-undergroundsearch-undergroundencode-url

    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 ×21

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