@remcp/runtime@0.2.206
First-party ReMCP local device runtime: filesystem, terminal, computer-use, browser, diagnostics and document tools over MCP.
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe package discloses runtime telemetry and allows users to disable it, but the payload includes a machine hostname by default. That identifying detail makes the telemetry suspicious under the review rules.
Static reason
One or more suspicious static signals were detected.
Trigger
Runtime startup enables telemetry by default; recorded events are sent when the buffer flushes.
Impact
The receiving ReMCP account can associate usage metrics with the machine's hostname.
Mechanism
The payload includes runtimeConfig.name, which falls back to os.hostname(), and is sent through the paired agent.
AI rationale
The package discloses runtime telemetry and allows users to disable it, but the payload includes a machine hostname by default. That identifying detail makes the telemetry suspicious under the review rules.
Evidence
src/config.mjssrc/telemetry.mjssrc/index.mjs
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- Telemetry is enabled by default unless disabled by configuration.
- The telemetry payload includes runtimeConfig.name, which defaults to os.hostname().
- The runtime says these metrics go to the user's ReMCP account through the paired agent.
Evidence against
- Telemetry events use a whitelist that excludes file paths, commands, arguments, and tool output.
- The runtime discloses telemetry and provides settings to disable it.
- The reviewed screenshot and D-Bus behavior is tied to screenshot functionality rather than an unrelated data collection flow.
