Security Findings (15)

• HighExcessive Permission Surface ×2

  • TICKTICK_OAUTH2_AUTHORIZATION_STEP1:tool declares network permission
  • TICKTICK_OAUTH2_AUTHORIZATION_STEP_1:tool declares network permission

  Rule: AS-002Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
• HighTool Shadowing

  TICKTICK_OAUTH2_AUTHORIZATION_STEP_1:tool name "TICKTICK_OAUTH2_AUTHORIZATION_STEP_1" duplicates "TICKTICK_OAUTH2_AUTHORIZATION_STEP1" already registered in this tool set — a malicious server can shadow a trusted tool by registering an identical name

  Rule: AS-013Fix: Two or more tools registered in your MCP environment share an identical or near-identical name. A malicious server can shadow a trusted tool this way, intercepting calls you intend for the legitimate tool. Remove the conflicting server or rename its tools to be unambiguous.
• MediumExcessive Permission Surface ×8

  • TICKTICK_CREATE_PROJECT:tool declares fs permission
  • TICKTICK_CREATE_TASK:tool declares fs permission
  • TICKTICK_DELETE_PROJECT:tool declares fs permission
  • TICKTICK_DELETE_TASK:tool declares fs permission
  • TICKTICK_OAUTH2_AUTHORIZATION_STEP1:tool declares fs permission
  • TICKTICK_OAUTH2_AUTHORIZATION_STEP_1:tool declares fs permission
  • TICKTICK_UPDATE_PROJECT:tool declares fs permission
  • TICKTICK_UPDATE_TASK:tool declares fs permission

  Rule: AS-002Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
• LowExcessive Permission Surface ×2

  • TICKTICK_CREATE_TASK:input schema exposes 13 properties (threshold: 10)
  • TICKTICK_UPDATE_TASK:input schema exposes 14 properties (threshold: 10)

  Rule: AS-002Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.
• LowDoS Resilience — Missing Rate Limit / Timeout ×2

  • TICKTICK_OAUTH2_AUTHORIZATION_STEP1:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration
  • TICKTICK_OAUTH2_AUTHORIZATION_STEP_1:tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

  Rule: AS-011Fix: 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.
