MCP server for terminal operations and file editing

AI Security Review

scanned 3h ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. No unconsented install-time agent control hijack was confirmed. The risky surface is explicit user-invoked Claude MCP setup plus telemetry and broad MCP filesystem/shell tools.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm postinstall verifies ripgrep; user runs setup/bin or desktop-commander setup for Claude config mutation

Impact

Warn-level agent extension lifecycle risk, not confirmed malware

Mechanism

explicit MCP server setup and telemetry collection

Rationale

Static inspection does not show credential theft, destructive behavior, remote payload execution, or unconsented postinstall mutation of Claude config. Because explicit setup mutates an AI-agent control surface and package identity is inconsistent with the configured upstream package name, warn rather than block.

Evidence

package.jsondist/npm-scripts/verify-ripgrep.jsdist/setup-claude-server.jsdist/track-installation.jsdist/index.jsdist/utils/capture.jsdist/config-manager.jsdist/uninstall-claude-server.js

Network endpoints2

telemetry.desktopcommander.app/mp/collectdc-telemetry-proxy-83847352264.europe-west1.run.app/mp/collect

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

dist/setup-claude-server.js explicit setup command writes Claude Desktop MCP config and restarts Claude.
dist/setup-claude-server.js and dist/track-installation.js send install/setup telemetry to telemetry.desktopcommander.app with environment/install context.
package.json metadata/bin setup references desktop-commander but setup config installs @wonderwhy-er/desktop-commander, not @tokor/desktop-commander.

Evidence against

package.json postinstall only runs dist/npm-scripts/verify-ripgrep.js and ignores failure.
dist/npm-scripts/verify-ripgrep.js only resolves ripgrep path and prints warnings; no config writes or network.
dist/index.js setup/remove/remote actions are argument-gated; normal import starts MCP server.
dist/utils/capture.js supports telemetry opt-out via config and DESKTOP_COMMANDER_DISABLE_TELEMETRY.
Shell/file/process capabilities are MCP server features aligned with package description.
