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 (127)

  • MediumAS-003

    🔀Scope Mismatch

    set_subscriber_traffic_restrictions:tool name "set_subscriber_traffic_restrictions" implies local write operation but only remote/network-class permissions were detected

    Fix: Ensure tool names, descriptions, and permission declarations are internally consistent. Use explicit naming conventions that fully reflect actual capabilities.

    ℹ️Missing Rate-Limit / Timeout ×29

    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.

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

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×65

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

    Fix: Review and remediate the identified issue.

  • InfoAS-010

    🔑Insecure Secret Handling

    carrier_ask:input parameter "confirm_token" accepts a credential (informational; not evidence of insecure handling)

    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.

Scan this tool yourself

Reproduce this audit locally, integrate into CI, or let your agent audit its own tools.

Install once, then scan any MCP server:

$ curl -sfL https://raw.githubusercontent.com/AgentSafe-AI/tooltrust-scanner/main/install.sh | bash
$ tooltrust-scanner scan --server "npx -y carrier-mcp"

Adjust the package name if your npm registry name differs from the tool ID. View source
