The ask_google tool is well-defined with explicit schema, good descriptions, and strong tool annotations. The tool exhibits production-grade quality: comprehensive input schema with dual-parameter alias support (question/query), extensive output schema documenting grounding status and citations, parameter descriptions that guide LLM behavior (e.g., 'Prefer current/latest/as of today'), and security/idempotency annotations. Security measures are evident in source URL validation and markdown escaping. However, the single-tool design limits composition opportunities, and the server is STDIO-only which impacts protocol accessibility.

• Migrate from STDIO to HTTP with SSE or Streamable HTTP transport for remote accessibility and integration with hosted MCP clients
• Consider adding optional tools like 'compare_google_results' (side-by-side search on multiple queries) or 'ask_google_with_date_range' to enable richer agent compositions
• Evaluate whether diagnostics (ttft_ms, total_attempts) in output schema are critical for agents; consider moving these to server-side logs or making them optional to reduce token usage
• Add explicit rate-limiting guidance in documentation to prevent runaway agent loops from overwhelming the Google Gemini API

Inferred effective spec: 2026-07-28+.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
