MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.80). The skill explicitly instructs adding the Clueso connector using "claude mcp add --transport http Clueso https://connect.clueso.io/mcp", which at runtime contacts that external endpoint to enable the assistant to use/execute Clueso MCP tools, so the https://connect.clueso.io/mcp URL is a runtime dependency that enables remote tool execution.
