Instructions file for Claude Code

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

This is RyanLisse/mexc-mcp-server's own configuration. It tells Claude Code how to work on mexc-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 mexc-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

mexc-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.

Architecture Overview

This is a MEXC cryptocurrency exchange MCP (Model Context Protocol) server built with vertical slice architecture:

Technology Stack

  • Runtime: Bun (3x faster than Node.js)
  • Framework: Encore.ts microservices framework
  • Language: TypeScript with strict type checking
  • Validation: Encore.ts built-in validation with TypeScript
  • Linting: Biome.js (35x faster than ESLint)
  • Testing: Bun's built-in test runner

Service Architecture

The project follows Encore.ts microservice patterns with separate services:

  • Root Service (encore.service.ts): Main MCP server
  • Auth Service (auth/): API key validation and authentication
  • Market Data Service (market-data/): Live MEXC API integration

Vertical Slices (Complete Features)

  1. Authentication & API Key Management ✅ (21 tests, 100% coverage)
  2. Market Data MCP Tools ✅ (28 tests, 96.30% coverage, live API)

Key Files

  • shared/config.ts - Environment configuration with validation
  • shared/types/index.ts - Common TypeScript interfaces
  • market-data/mexc-client.ts - Real MEXC API client with HMAC auth
  • market-data/tools.ts - MCP tool implementations
  • auth/auth.ts - API key validation and rate limiting

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.
