In plain words
What is it for?

Why use it?
It gives a coding agent the repository context needed to work on the project without guessing how its parts fit together.

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is brentmid/evernote-mcp-server's own configuration. It tells Claude Code how to work on evernote-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything evernote-mcp-server configures →

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.

Security

Grade A, and why

evernote-mcp-server 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 8d 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 local Evernote MCP (Model Context Protocol) server that connects Claude Desktop with Evernote accounts. It provides read-only access to Evernote notes through MCP calls like createSearch, getNote, and getNoteContent. Version 2.0 includes production-ready containerization and enhanced MCP protocol compliance for both local stdin/stdout and remote HTTP/JSON-RPC integration.

Architecture

  • Language: Node.js with Express framework
  • Container base images: Red Hat Project Hummingbird Node.js images (quay.io/hummingbird/nodejs:latest-builder for build stage, quay.io/hummingbird/nodejs:latest for production)
  • External services: Evernote API using OAuth 1.0a authentication
  • Main entry point: index.js - HTTPS server with OAuth integration
  • Authentication module: auth.js - handles complete OAuth 1.0a flow
  • Authentication: OAuth 1.0a flow (NOT OAuth 2.0), tokens automatically persisted in .env file
  • Security model: Read-only Evernote access, HTTPS-only server, no third-party data transmission except to Evernote
  • MCP compliance: Implements both stdin/stdout MCP protocol (mcp-server.js) and HTTP/JSON-RPC remote server protocol (index.js /mcp endpoint)
  • Dual integration modes: Local Claude Desktop integration via mcp-server.js or remote integration via HTTPS JSON-RPC at /mcp endpoint

Development Commands

Local Development

  • Install dependencies: npm install
  • Set environment variables: Add EVERNOTE_CONSUMER_KEY and EVERNOTE_CONSUMER_SECRET to the .env file (both index.js and mcp-server.js load .env via dotenv)
  • Enable debug logging (optional): export DEV_MODE=true for detailed API request/response logging
  • Generate SSL certificates: mkdir cert && openssl req -x509 -newkey rsa:4096 -keyout cert/localhost.key -out cert/localhost.crt -days 365 -nodes -subj "/C=US/ST=Local/L=Local/O=Local/OU=Local/CN=localhost"
  • Run server: npx node index.js (requires SSL certificates and Evernote API credentials)

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.
