Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Explicit `agent install claude --apply` upserts a user-scope Claude MCP server.
- The applied configuration launches this package through `npx` with an API-key environment variable.
Evidence against
- package.json has no preinstall/install/postinstall lifecycle hook.
- The installer binary only prints setup instructions.
- Codex and Claude Desktop paths render configuration rather than write it.
