What is nytimes-mcp CLAUDE.md?

A Claude Code repository guide for nytimes-mcp, a FastMCP server that provides access to New York Times APIs. It documents the server's five API tools, three reference resources, setup commands, and required NYT_API_KEY.

Use it when developing, testing, or running nytimes-mcp, including configuring its New York Times API key and starting the MCP server.

It tells a coding agent how this repository is structured, installed, run, and tested instead of making it infer those details.

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	$0.01292	$0.01292
Opus 5	$0.00646	$0.00646
Sonnet 5	$0.00258	$0.00258

Security

Grade A, and why

nytimes-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 9d 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 a FastMCP-based Model Context Protocol (MCP) server that provides access to the New York Times APIs. The server exposes 5 tools (one per NYT API endpoint) and 3 reference resources to MCP clients like Claude Desktop.

Development Commands

Environment Setup

# Install dependencies
uv sync

# Install as editable package
uv tool install .

Running the Server

# Development mode with MCP Inspector UI (interactive testing)
uv run fastmcp dev src/nytimes_mcp/server.py:mcp

# Production mode (for use with MCP clients)
uvx nytimes-mcp

# Alternative production mode
fastmcp run src/nytimes_mcp/server.py:mcp

Testing

# Run tests
uv run pytest

Environment Variables

Required environment variable: NYT_API_KEY

Set in .env file: NYT_API_KEY=your_api_key_here
Or export: export NYT_API_KEY=your_api_key_here
Get API keys at: https://developer.nytimes.com/

Architecture

Core Components

server.py - FastMCP server initialization and tool/resource registration

Initializes FastMCP instance with dependencies
Loads environment variables and validates NYT_API_KEY
Registers all MCP tools (5 total) and resources (3 total)
Each @mcp.tool() decorator wraps a corresponding function from tools.py
Each @mcp.resource() decorator wraps a corresponding function from resources.py
Main entry point handles cleanup of HTTP client on shutdown

tools.py - NYT API tool implementations

Defines type aliases for Literal types (NewsSource, SortOrder, PopularityType, PopularityPeriod)
Implements 5 primary tools: search_articles, get_news_wire, get_most_popular, get_archive, get_bestseller_list
Also provides helper functions: get_news_sections, get_bestseller_list_names, get_bestseller_lists_overview
Uses module-level singleton _nyt_client instance for HTTP connection pooling
Calls formatting utilities from utils.py for most endpoints (archive and bestseller return raw responses)
Provides cleanup_http_client() for proper resource cleanup

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.
