@remcp/runtime@0.2.164
First-party ReMCP local device runtime: filesystem, terminal, computer-use, browser, diagnostics and document tools over MCP.
AI Security Review
scanned 18d ago · by lpm-firewall-aiSource inspection found no install hook or concrete attack behavior. The flagged screenshot and network features serve local runtime capabilities, while telemetry is bounded and routed through the paired agent.
Static reason
One or more suspicious static signals were detected.
Trigger
The runtime starts when invoked; individual capabilities run when their MCP tools are called.
Impact
No harmful effect or unauthorized data transfer was established.
Mechanism
Screenshot capture uses the local desktop portal or local capture utilities. Telemetry contains whitelisted runtime and tool metadata and is sent through the paired agent.
AI rationale
Source inspection found no install hook or concrete attack behavior. The flagged screenshot and network features serve local runtime capabilities, while telemetry is bounded and routed through the paired agent.

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 has no install lifecycle hook; its scripts are start, check, and test.
- The screenshot portal requests a screenshot through the local desktop portal and accepts only a local file URI.
- The screenshot tool runs on request and returns the captured image through the runtime tool response.
- The entrypoint starts the MCP server when the runtime process is invoked.
- Telemetry whitelists tool metadata and sends it through the paired ReMCP agent; the user can disable it.
- The browser CDP default endpoint is loopback.

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