MCP-Control CLAUDE.md is an instructions file for Claude Code from ALLezSung/MCP-Control. It costs 1,665 tokens per session, scanned A, a copy of MCP-Control AGENTS.md, MIT.

A repository instruction file for Claude Code, an AI coding tool. It documents build, formatting, linting, testing, end-to-end testing, and HTTPS setup for the MCP-Control project.

In plain words
What is it for?
It is for maintaining MCP-Control, including compiling it, checking code quality, running tests, and starting secure HTTPS connections.
Why use it?
It gives the coding agent the project's expected commands and runtime requirements before it changes or checks code.

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

This is ALLezSung/MCP-Control's own configuration. It tells Claude Code how to work on MCP-Control 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 MCP-Control 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

MCP-Control 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.

Origin

This is a copy

94% identical to MCP-Control AGENTS.md — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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

Build & Test Commands

  • Build: pwsh.exe -c "npm run build" - Compiles TypeScript to JavaScript
  • Lint: pwsh.exe -c "npm run lint" - Runs ESLint to check code quality (TS and JS)
  • Format: pwsh.exe -c "npm run format" - Runs Prettier to format code
  • Format Check: pwsh.exe -c "npm run format:check" - Checks if files are properly formatted
  • Test: pwsh.exe -c "npm run test" - Runs all Vitest tests
  • Run single test: pwsh.exe -c "npm run test -- tools/keyboard.test.ts" or pwsh.exe -c "npm run test -- -t \"specific test name\""
  • Watch tests: pwsh.exe -c "npm run test:watch" - Runs tests in watch mode
  • Coverage: pwsh.exe -c "npm run test:coverage" - Generates test coverage report
  • E2E Test: cd test && ./e2e-test.sh [iterations] - Runs end-to-end tests with Claude and MCPControl

Running with HTTPS/TLS

MCPControl supports HTTPS for secure SSE connections (mandatory per MCP spec for production):

  • node build/index.js --sse --https --cert /path/to/cert.pem --key /path/to/key.pem
  • Default HTTPS port is still 3232 (use --port to change)
  • Both --cert and --key are required when using --https

Note: MCP Servers are typically launched by the Client as a subprocess.

Architecture

Dual Transport

The server always connects via stdio (StdioServerTransport). When --sse is passed, an Express HTTP server is also started on port 3232 (configurable via --port), exposing:

  • GET /mcp — SSE endpoint (each client gets an SSEServerTransport tracked by sessionId)
  • POST /mcp?sessionId=... — bidirectional message handling
  • GET /metrics — Prometheus-style active connection count

Provider Pattern (Core Abstraction)

All system interaction goes through the AutomationProvider interface (src/interfaces/provider.ts), which composes four sub-interfaces defined in src/interfaces/automation.ts:

  • KeyboardAutomation — typeText, pressKey, pressKeyCombination, holdKey
  • MouseAutomation — moveMouse, clickMouse, doubleClick, dragMouse, scrollMouse, clickAt, getCursorPosition
  • ScreenAutomation — getScreenSize, getActiveWindow, focusWindow, resizeWindow, repositionWindow, getScreenshot
  • ClipboardAutomation — getClipboardContent, setClipboardContent, hasClipboardText, clearClipboard

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.
