Security audit

London public transport journey planner and disruptions

Security checks across malware telemetry and agentic risk

Overview

This is a straightforward TfL journey-planning skill that sends route details to TfL and does not show hidden or unrelated behavior.

Install only if you are comfortable sending journey start/end locations and travel times to TfL. If you configure TFL_APP_ID or TFL_APP_KEY, the helper will include those credentials in TfL API requests.

MCP Least Privilege
Confidence

Finding
The skill explicitly instructs use of a Python helper that performs network calls to the TfL API and may read credentials from environment variables, yet the skill declares no corresponding permissions. This creates a permission mismatch that can bypass least-privilege review expectations and obscure the skill's actual capabilities to operators and users.
