What is mcp-picnick CLAUDE.md?

Project instructions for an MCP server that searches Google Images and downloads selected images. MCP, or Model Context Protocol, is a way for an AI assistant to use tools provided by another program.

Use it when developing this project: build the server, run its tests, check code style and TypeScript types, or understand its tools and folder structure.

It gives contributors one reference for building, testing, checking, and understanding the server. This avoids guessing which commands to run or where the main code and tools are located.

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	$0.00712	$0.00712

Security

Grade A, and why

mcp-picnick 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 7d 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.

Project Overview

This is an MCP (Model Context Protocol) server for Google Images Search that allows searching and downloading images through Google Custom Search API. The server provides two main tools: search_image for finding images and persist_image for downloading them to local storage.

Development commands

building

pnpm build - Production build using ncc (creates dist/cli.js executable)
pnpm build:tsc - TypeScript compilation with alias resolution
pnpm dev - Development mode with file watching (uses chokidar to recompile on changes)

testing and quality

pnpm test - Run tests using Vitest
pnpm lint - Run ESLint checks
pnpm lint:fix - Fix ESLint issues automatically
pnpm tsc - TypeScript type checking without emitting files

Architecture

key dependencies

@modelcontextprotocol/sdk - MCP server framework
winston - Logging (logs to logs/info.log)
zod - Schema validation for tool parameters

core Structure

Entry Point: src/index.ts - Sets up MCP server with Winston logging and registers tools
Tools: Located in src/tools/ directory with separate folders for each tool
Utilities: src/utils/tryCatch.ts - Error handling utility for async operations

tool architecture

Each tool follows a consistent pattern:

index.ts - Exports schema and handler factory function
utils.ts - Business logic and API integration
README.md - Tool documentation

error handling

The codebase uses a custom tryCatch utility that wraps operations in a Result-like pattern returning [error, data] tuples. This provides type-safe error handling without throwing exceptions.

environment variables

API_KEY - Google Cloud API key
SEARCH_ENGINE_ID - Google Custom Search Engine ID

Tool Details

search_image

Purpose: Search for images using Google Custom Search API
Location: src/tools/search_image/
Key Parameters: query (required), count (1-10), safe search settings
Returns: Image metadata with thumbnails and full-size links

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.
