@remcp/runtime@0.2.48
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 hook or self-dependency chain, and the flagged behaviors examined align with local runtime functionality. The scanner’s structural hints do not establish an attack.
Static reason
One or more suspicious static signals were detected.
Trigger
Running the remcp-runtime CLI starts its local MCP service; browser access occurs when browser tools are invoked.
Impact
No confirmed malicious effect or attack surface was established.
Mechanism
No install-time mutation or remote endpoint control was identified in the inspected sources; browser endpoint validation requires a loopback host.
AI rationale
Source inspection found no install hook or self-dependency chain, and the flagged behaviors examined align with local runtime functionality. The scanner’s structural hints do not establish an attack.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json defines ordinary start, check, and test scripts, with no install lifecycle hook or self-dependency.
- src/index.mjs starts a local MCP server as the runtime’s CLI behavior.
- src/extended/browser.mjs restricts browser debugging endpoints to loopback hosts.
- src/extended/documents.mjs rejects absolute and traversal paths in archive entries.
- src/helpers/wayland-eis-helper.py uses the desktop portal RemoteDesktop interface for its stated input helper.

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