Best for
  • Developers who have at least one supported provider CLI installed and authenticated, or the relevant API keys configured
  • Teams that want cross-model code review and plan debate inside their coding workflow
  • Users who need private or offline review via Ollama
  • Users of MCP clients such as Claude Code, Codex CLI, Cursor, and Claude Desktop
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Users without any provider CLI installed or keys configured (the server does not supply model access itself)
  • Environments that cannot install Node.js 20+ or are not Linux/macOS
  • Users expecting a fully hosted, zero-config, or officially supported product
  • Scenarios where outbound data transfer is strictly forbidden and no local provider such as Ollama is available
  • Projects outside the NPM ecosystem (e.g., pure Python/Go)
  • Environments without network access to deps.dev, OSV.dev, and the npm registry
  • Scenarios requiring maintenance by an official upstream vendor
Required permissions
  • Read local workspace files for context (e.g. Claude provider's Read/Glob/Grep-only access, Gemini's @ file syntax)
  • Launch and call installed provider CLIs locally (codex, claude, agy, gemini, agent, etc.)
  • Network access to call the xAI API (when using XAI_API_KEY) and the local Ollama service (default http://localhost:11434)
  • Read API keys from environment variables (e.g. XAI_API_KEY, CURSOR_API_KEY)
  • Cursor Agent runs in read-only ask mode and does not change force/trust/spend settings
  • Network access to the NPM registry and external services (deps.dev, OSV.dev, OpenSSF, npms.io, GitHub)
  • Read access to workspace lockfiles (pnpm-lock.yaml, package-lock., yarn.lock) for cache invalidation
Risks and side effects
  • Code and prompts may be sent to external model providers, creating data-transfer exposure; choose Ollama when local privacy is required
  • Metered endpoints such as the xAI API incur real costs; ASK_GROK_MAX_OUTPUT_TOKENS only bounds spend, it does not make it free
  • Grok and Ollama never fall back to another model, so requests may fail outright
  • Gemini CLI has been enterprise-seat-only since 2026-06-18; non-enterprise accounts get guidance instead of output
  • Antigravity is experimental and one-shot, with limited reliability
  • Plugin workflows such as codex-pair can trigger repeated external calls and costs, requiring an explicit marker and consent
  • This is a third-party, unofficial tool with no affiliation with or endorsement by Anthropic, Google, OpenAI, or xAI
  • Third-party READMEs and changelogs are untrusted external content; they are wrapped in tags with _meta flags but should still be handled cautiously
  • Depends on availability and accuracy of external services
  • Batch requests are capped at 25 packages to prevent registry enumeration; larger sets require batching
  • Third-party open source project, not officially maintained by NPM or Anthropic
