@sentropic/h2a-runtime@0.97.5
h2a heavy runtime (sessions / k8s / tunnel, node-pty + aws-sdk). Lazily imported by @sentropic/h2a; installed separately.
AI Security Review
scanned 26d ago · by lpm-firewall-aiThe source supports a warning for explicit agent configuration mutation through plugin management. No install hook or concrete malicious behavior was established, so this is not a publish block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user invokes the plugin management command to add or configure a plugin.
Impact
The configured agent may launch the registered plugin server in later sessions; no unconsented install-time mutation or confirmed attack was identified.
Mechanism
The CLI adds MCP server entries to the user's Claude or Codex configuration files.
AI rationale
The source supports a warning for explicit agent configuration mutation through plugin management. No install hook or concrete malicious behavior was established, so this is not a publish block.
Evidence
dist/index.jsdist/plugin.jsdist/config.js~/.claude.json~/.codex/config.toml
Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package has no preinstall, install, or postinstall hook; its CLI is exposed through the package entrypoint.
- The `remote plugin` command supports installing plugins and registering their MCP servers with agent CLIs.
- Plugin registration writes MCP server configuration to the user's Codex and Claude configuration files.
- These writes are reached through explicit plugin commands; no install-time caller was identified.
Evidence against
- The package manifest identifies the `@sentropic/h2a-runtime` package and its CLI entrypoint.
- Hook installation and session migration code are separate from npm installation and are invoked through CLI operations.
- The inspected endpoint in the central MCP module is loopback-only.
