@remcp/runtime@0.2.205
First-party ReMCP local device runtime: filesystem, terminal, computer-use, browser, diagnostics and document tools over MCP.
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe package discloses opt-out telemetry and limits event details, but its payload also includes a runtime name that defaults to the machine hostname. Under the review rules, telemetry sent with identifying details warrants a warning.
Static reason
One or more suspicious static signals were detected.
Trigger
Runtime startup followed by telemetry flush during operation or shutdown.
Impact
The hostname can identify the user's machine in telemetry, creating a privacy risk.
Mechanism
The runtime name defaults to os.hostname(); telemetry batches include that name and are sent through the paired agent to the user's ReMCP account.
AI rationale
The package discloses opt-out telemetry and limits event details, but its payload also includes a runtime name that defaults to the machine hostname. Under the review rules, telemetry sent with identifying details warrants a warning.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Telemetry is enabled by default and can be disabled through configuration or an environment variable.
- The runtime name defaults to the machine hostname.
- Telemetry batches include that runtime name and are forwarded through the paired agent to the user's ReMCP account.
- The package discloses usage metrics and says they exclude file paths, commands, arguments, and tool output.
Evidence against
- Event details are whitelisted to limited fields such as tool names, timings, outcomes, and coarse error classes.
- The telemetry is disclosed, opt-out, and routed through the paired agent; the source names no direct external endpoint.
