First-party ReMCP local device runtime: filesystem, terminal, computer-use, browser, diagnostics and document tools over MCP.
AI Security Review
scanned 7d ago · by lpm-firewall-aiInspected source shows an explicitly started MCP runtime with local device and file operations, and no install hook or concrete attack behavior. The flagged DBus bridge supports desktop portal access, while the inspected dependency source shows ordinary MCP transport behavior.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user or configured MCP client starts the runtime and invokes an available tool.
Impact
These operations support the runtime's stated local device functions; inspected source did not establish covert collection, unrelated data transfer, or unconsented installation behavior.
Mechanism
Runtime handlers perform device operations, local screenshot capture, file operations, or desktop portal access.
AI rationale
Inspected source shows an explicitly started MCP runtime with local device and file operations, and no install hook or concrete attack behavior. The flagged DBus bridge supports desktop portal access, while the inspected dependency source shows ordinary MCP transport behavior.

Decision evidence
public snapshotAI called this Clean at 96.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json exposes an explicitly started CLI and declares runtime libraries; it has no install lifecycle hook.
- The system handlers expose device information, process listing, and process termination through runtime tools.
- Screenshot support invokes detected local screenshot utilities for the requested capture.
- The portal loads the DBus library for local desktop portal interaction.
- The inspected MCP server sources implement event subscription and stdio transport; the server package scripts shown are development tasks.
- File writes are bounded by the configured maximum size.
Evidence against
- The flagged dependency bridge is used for a local Wayland desktop portal, and the inspected files show no unrelated recipient or installation-time behavior.
- The flagged system and screenshot operations are exposed as runtime tools or invoked for capture; no concrete attack behavior was identified.

Copied Package Dependency Bridge
Package metadata claims a different repository identity while copied source loads a runtime dependency bridge.
