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-aiThe manifest has no install hook, and the flagged runtime and dependency code matches local screenshot and MCP transport functions. The inspected source does not establish a malicious attack surface.
Static reason
One or more suspicious static signals were detected.
Trigger
The paired agent invokes the runtime; screenshot capture runs when requested through its MCP tool.
Impact
The inspected paths establish no unauthorized external transfer, install-time mutation, or other concrete attack behavior.
Mechanism
The runtime communicates over stdio, uses session D-Bus for desktop portal screenshots, and forwards telemetry through its MCP server.
AI rationale
The manifest has no install hook, and the flagged runtime and dependency code matches local screenshot and MCP transport functions. The inspected source does not establish a malicious attack surface.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest points the executable to src/index.mjs and lists only start, check, and test scripts; it has no install lifecycle hook.
- The screenshot tool invokes local capture backends on request. On Wayland, it calls the desktop portal and accepts a local file URI.
- The supplied D-Bus dependency exposes a session bus client, matching the runtime’s portal use.
- The supplied MCP server snapshot implements event subscriptions and stdio transport; the inspected subscription filters events before forwarding notifications.
- File writes resolve the requested path and enforce the configured write-size limit.
- The runtime sends telemetry as an MCP notification, and telemetry recording checks the telemetry setting.

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