What is MCPControl CLAUDE.md?

A project guide for MCPControl, a tool that connects Claude to MCP services. It lists its build, code-checking, testing, and secure HTTPS/TLS run commands.

Use it to build MCPControl, format and lint its TypeScript and JavaScript, run Vitest or end-to-end tests, check coverage, and start secure server connections.

It gives a coding agent the project’s standard commands and rules in one place, reducing guesswork when changing or checking the code.

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	$0.00566	$0.00566
Opus 5.5	$0.00226	$0.00226
Sonnet 5.5	$0.00113	$0.00113
Haiku 4.5	$0.00057	$0.00057

Security

Grade A, and why

MCPControl 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.

MCPControl - Development Guide

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.

Code Style Guidelines

Imports: Use ES module syntax with named imports
Types: Define TypeScript interfaces for inputs/outputs in types/ directory
Error Handling: Use try/catch with standardized response objects
Naming: camelCase for variables/functions, PascalCase for interfaces
Functions: Keep functions small and focused on single responsibility
Comments: Add JSDoc comments for public APIs
Testing:
- Unit tests: Place in same directory as implementation with .test.ts suffix
- E2E tests: Added to the test/ directory
Formatting: Code is formatted using Prettier (pre-commit hooks will run automatically)
Error Responses: Return { success: false, message: string } for errors
Success Responses: Return { success: true, data?: any } for success
Linting: Both TypeScript and JavaScript files are linted with ESLint

Changes

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.
