-
NPM:
npm install -g @neverinfamous/mysql-mcp(recommended) -
Docker:
docker run -i --rm writenotenow/mysql-mcp:latest
- 230+ MySQL Tools across 25 categories
-
Deterministic Error Handling — structured
{success, error, code, category, suggestion, recoverable}on every tool - Audit Trail & Token Logging — JSONL forensic logging with pre-mutation snapshots
- 18 Resources for database observability
- 19 AI-Powered Prompts for guided workflows
-
Worker Sandbox Isolation — Code Mode executes in a separate V8 isolate via
worker_threadswith RPC bridge, enforced heap limits, and hard timeouts -
Token-Optimized Payloads — Tools with large responses offer optional
summary,limit, andcompactflags to reduce token usage - Tool Filtering Shortcuts (starter, dev-power, dba-monitor, etc.)
