@remcp/runtime@0.2.226
First-party ReMCP local device runtime: filesystem, terminal, computer-use, browser, diagnostics and document tools over MCP.
AI Security Review
scanned 1d ago · by lpm-firewall-aiThe flagged dependency bridge supports the on-demand local Wayland screenshot flow. Telemetry is disclosed, has opt-out controls, and excludes file paths, commands, arguments, and tool output; no malicious behavior was identified.
Static reason
One or more suspicious static signals were detected.
Trigger
The runtime starts when launched; telemetry is emitted during runtime when enabled, and screenshot capture runs when its tool is requested.
Impact
No malicious behavior was found in the reviewed paths; the documented metrics contain usage details, not file contents, paths, commands, or tool output.
Mechanism
Metrics are sent through the paired ReMCP agent using whitelisted event fields. Wayland screenshots use the local desktop portal and are copied to the requested destination.
AI rationale
The flagged dependency bridge supports the on-demand local Wayland screenshot flow. Telemetry is disclosed, has opt-out controls, and excludes file paths, commands, arguments, and tool output; no malicious behavior was identified.
Evidence
User-selected screenshot destination; temporary screenshot directory when no destination is supplied.
Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json lists start, check, and test scripts, with no install lifecycle hook.
- The runtime describes telemetry as opt-out, limited to tool names, timings, and outcomes, and provides ways to disable it.
- Telemetry fields are whitelisted; file paths, command strings, tool arguments, and tool output are excluded.
- The screenshot portal dependency is loaded only by the Wayland screenshot tool, which copies a screenshot returned by the local desktop portal.
- The README describes the paired-agent stdio model and says network diagnostics and commands reach the network only when requested.
