Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.02380	$0.02380
Opus 5.5	$0.00952	$0.00952
Sonnet 5.5	$0.00476	$0.00476
Haiku 4.5	$0.00238	$0.00238

Security

Grade A, and why

ask-google-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is a Model Context Protocol (MCP) server that provides AI-powered Google search using Gemini with search grounding. It enables Claude Desktop and other MCP clients to perform real-time web searches with AI-synthesized answers and citations.

Key Technologies:

MCP SDK (@modelcontextprotocol/sdk) for stdio server transport and JSON-RPC 2.0 communication
Google Generative AI SDK (@google/generative-ai) for Gemini API integration
Node.js native test runner for unit/integration testing
ES modules (type: "module" in package.json)

Development Commands

Running the Server

npm start                    # Start MCP server
npm run start:checked        # Validate .env first, then start
npm run dev                  # Auto-reload mode with --watch flag

Testing

npm test                     # Unit tests only (test/unit/**/*.test.js)
npm run test:integration     # Integration test with live Gemini API
npm run test:all             # All tests (unit + integration)

Running a single test file:

node --test test/unit/tool-handler.test.js

Environment & Security

npm run check-env            # Validate .env configuration
npm run security:audit       # Check for vulnerabilities
npm run security:fix         # Auto-fix security issues
npm run security:update      # Update deps and audit

Architecture

MCP Server Design

The server implements a single-tool MCP server following the stdio transport pattern:

Server Initialization (src/index.js:117-128)
- Creates MCP Server instance with name/version metadata
- Declares tools capability
- Connects to StdioServerTransport for JSON-RPC communication
Tool Registration (src/index.js:131-176)
- Handles ListToolsRequestSchema to expose the ask_google tool
- Tool description is optimized for AI agent invocation with clear trigger phrases
- Input schema includes validation rules and examples

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
