@remcp/runtime@0.2.200
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 routed through the paired agent, but its payload also includes a name that defaults to the host name. This is identifying telemetry not covered by the stated collection description, so it warrants a warning rather than a block.
Static reason
One or more suspicious static signals were detected.
Trigger
Runtime telemetry is enabled by default; buffered events are sent when the telemetry sink flushes them.
Impact
The host name can identify the user's machine when associated with their ReMCP account; this collection is not disclosed in the CLI's stated list of telemetry fields.
Mechanism
The telemetry payload includes runtimeConfig.name, whose default is os.hostname(), and the entry point forwards the payload as an MCP telemetry notification.
AI rationale
The package discloses opt-out telemetry routed through the paired agent, but its payload also includes a name that defaults to the host name. This is identifying telemetry not covered by the stated collection description, so it warrants a warning rather than a block.
Evidence
src/config.mjssrc/telemetry.mjssrc/index.mjs
Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Runtime telemetry is enabled by default unless disabled by configuration.
- The telemetry payload includes runtimeConfig.name, which defaults to os.hostname() when no custom name is set.
- The telemetry sink sends the payload as an MCP notification through the paired agent.
- The CLI describes telemetry as including only tool names, timings and outcomes, but the payload also includes the runtime name.
Evidence against
- Telemetry is disclosed and has an opt-out.
- Telemetry fields exclude tool arguments, file paths, commands and output.
- The package declares no install lifecycle scripts; telemetry runs through the paired agent rather than a hard-coded third-party endpoint.
