@remcp/runtime@0.2.203
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’s disclosed, opt-out telemetry sends tool usage through the paired ReMCP agent, but its payload also includes a runtime name that defaults to the machine hostname. That identifying detail makes the runtime telemetry suspicious.
Static reason
One or more suspicious static signals were detected.
Trigger
The runtime starts with telemetry enabled; events are buffered and sent periodically or during shutdown.
Impact
The hostname can identify the machine alongside its tool usage. The package discloses telemetry and offers an opt-out, but the identifying detail makes this telemetry suspicious under the review rules.
Mechanism
Telemetry is sent as an MCP notification to the paired ReMCP agent, and its payload includes runtimeConfig.name, which defaults to os.hostname().
AI rationale
The package’s disclosed, opt-out telemetry sends tool usage through the paired ReMCP agent, but its payload also includes a runtime name that defaults to the machine hostname. That identifying detail makes the runtime telemetry suspicious.
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
- Runtime telemetry is enabled by default and can be disabled through configuration.
- Telemetry includes a runtime name that defaults to the machine hostname, alongside tool usage data.
- The runtime sends telemetry notifications to the paired ReMCP agent; no destination host is specified in this package.
Evidence against
- The package describes its telemetry and provides an opt-out.
- Telemetry events are limited to tool names, timings, outcomes and coarse error classes; they exclude paths, commands, arguments and tool output.
- The manifest has no lifecycle hooks, and the screenshot portal loads its D-Bus dependency only when capture is requested.
