First-party ReMCP local device runtime: filesystem, terminal, computer-use, browser, diagnostics and document tools over MCP.
AI Security Review
scanned 27d ago · by lpm-firewall-aiSource inspection found no install lifecycle hook or concrete malicious behavior. The flagged source is consistent with the package’s local device runtime, and its browser endpoint is restricted to loopback.
Static reason
One or more suspicious static signals were detected.
Trigger
The executable entry point runs when invoked by a user; document editing and browser operations are requested through runtime tools.
Impact
No confirmed malicious effect or package-triggered install-time action was established.
Mechanism
Document edits use caller-provided paths and operations. Browser debugging requests validate that the endpoint hostname is loopback.
AI rationale
Source inspection found no install lifecycle hook or concrete malicious behavior. The flagged source is consistent with the package’s local device runtime, and its browser endpoint is restricted to loopback.

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 defines start, check, and test scripts but no install lifecycle hook; it identifies the package’s first-party repository.
- src/extended/documents.mjs exposes document editing through caller-supplied paths and operations, resolving paths before editing.
- src/extended/browser.mjs limits the browser debugging endpoint to loopback hosts.
- src/extended/desktop-linux.mjs imports local device and Wayland helpers; the inspected source shows no runtime dependency bridge.

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