@remcp/runtime@0.2.204
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 runtime sends default-on telemetry through the paired agent and includes a name that defaults to the machine hostname, which is an identifying detail. The package provides an opt-out and excludes paths, commands, arguments, and tool output, so this warrants a warning rather than a block.
Static reason
One or more suspicious static signals were detected.
Trigger
Runtime startup enables telemetry by default; recorded events are sent when the batch flushes.
Impact
The paired ReMCP service may receive a hostname identifying the user's machine, despite the package's description of the metrics as only tool names, timings, and outcomes.
Mechanism
The runtime sets a telemetry sink that forwards payloads as MCP notifications through the paired agent. The payload includes runtimeConfig.name, which defaults to os.hostname().
AI rationale
The runtime sends default-on telemetry through the paired agent and includes a name that defaults to the machine hostname, which is an identifying detail. The package provides an opt-out and excludes paths, commands, arguments, and tool output, so this warrants a warning rather than a block.
Evidence
src/config.mjssrc/telemetry.mjssrc/index.mjs
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The telemetry name defaults to the machine hostname when no configured name is set.
- Telemetry batches include runtimeConfig.name alongside runtime version, platform, and architecture.
- The runtime forwards telemetry through an MCP notification to the paired agent.
- Telemetry is enabled by default and can be disabled by the user.
- Events are whitelisted to exclude file paths, commands, arguments, and tool output.
Evidence against
- The package describes metrics as tool names, timings, and outcomes sent through the paired agent to the user's own ReMCP account, and provides an opt-out.
- The screenshot portal imports its declared D-Bus dependency only when a screenshot is requested; this matches the package's desktop-capture purpose.
