• CriticalAS-006

  💻Arbitrary Code Execution

  heuristic signal

  blender_mcp_call:tool name or description implies arbitrary script/code execution (evaluate_script, execute javascript, etc.)

  Fix: This tool can execute arbitrary code or shell commands on the host system. Remove it unless strictly required. If kept: (1) restrict access to trusted users/agents only, (2) require human approval before each invocation (Claude Desktop: set approval_required: true; other clients: enable equivalent confirmation), (3) use the most restrictive sandbox or read-only mode available, and (4) never expose this tool to untrusted input sources.

• MediumAS-003

  🔀Scope Mismatch ×6

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

  set_print_speed

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

  set_airduct_mode

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

  set_temperature

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

  set_fan_speed

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

  set_light

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

  set_ams_drying

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

• LowAS-011

  ℹ️Missing Rate-Limit / Timeout ×26

  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.

  ⚠️Excessive Permissions ×6

  input schema exposes 29 properties (threshold: 10)

  slice_with_template

  input schema exposes 33 properties (threshold: 10)

  slice_stl

  input schema exposes 48 properties (threshold: 10)

  print_3mf_bambu_network

  input schema exposes 12 properties (threshold: 10)

  upload_file

  input schema exposes 35 properties (threshold: 10)

  print_3mf

  input schema exposes 14 properties (threshold: 10)

  print_collar_charm

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

  🔑Insecure Secret Handling ×28

  input parameter "bambu_token" accepts a credential (informational; not evidence of insecure handling)

  input parameter "password" accepts a credential (informational; not evidence of insecure handling)

  print_3mf_bambu_network

  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.
