  Fix: The set of tools exposed by this server changed between scans of the same version — a sign the package was silently updated without a version bump. Audit the changelog and all tool definitions before trusting this server. Pin to a specific commit hash rather than a floating version tag.

  ⚠️Excessive Permissions ×2

  input schema exposes 13 properties (threshold: 10)

  mailkite_send

  input schema exposes 11 properties (threshold: 10)

  mailkite_update_broadcast

  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 ×12

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

  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.

  🔑Insecure Secret Handling

  mailkite_verify_webhook:input parameter "secret" 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.
