What problem does it solve? Choosing from the large MCP server ecosystem is risky: too many servers slow agents down, and servers handling money or production data can cause irreversible damage. This Skill provides a curated catalog of 50 vetted MCP servers with install commands, safety flags, and selection rules so users pick the right servers without tool bloat or security incidents. ## Core Features & Use Cases - Curated Server Catalog: 50 MCP servers organized into 9 categories (core dev, databases, ops/infra, productivity, fintech, web3, trading, creator tools, reasoning) with install commands for Claude Code, Codex, and Gemini CLI. - Safety Guardrails: Explicit warnings and sandbox/testnet configuration patterns for servers that handle money, production databases, or irreversible on-chain transactions. - Selection Decision Tree: Role-based recommendation logic that enforces a 5-7 server limit and prefers official servers over community ones. - Use Case: A backend engineer asks which MCP servers to install for a Postgres project. The Skill recommends Postgres pointed at a read replica, GitHub, and Sentry, provides the exact claude mcp add commands, and warns against connecting to the production primary database. ## Quick Start Ask the agent to recommend MCP servers for your role, for example: "What MCP servers should I install for web3 development?"
