Install once, get 24 superpowers. Claude 101 is an MCP server that gives Claude real computation abilities — statistics, code analysis, SQL parsing, financial math, and more — things LLMs cannot do reliably on their own.

How it works:

You: "Compare React, Vue, and Svelte for our project"
  ↓
Skill tells Claude to call build_comparison_matrix
  ↓
MCP tool computes: Vue 8.1 > React 7.9 > Svelte 7.5 (weighted scoring)
  ↓
Claude writes: "Vue leads by 0.2 points. The result is sensitive to
               the DX weight — if you value Ecosystem more, React wins."

Without claude-101: Claude guesses at numbers and rankings. With claude-101: Claude uses precise computation, then reasons about the results.

Add to your .mcp.json (project root or ~/.claude/.mcp.json):

{
  "mcpServers": {
    "claude-101": {
      "command": "uvx",
      "args": ["--from", "claude-101[mcp]", "claude-101-server"]
    }
  }
}

The Skill teaches Claude *when* to call each tool and *how* to use every field in the result:

mkdir -p ~/.claude/skills
curl -sL https://raw.githubusercontent.com/claude-world/claude-101/main/skills/claude-101-mastery.md \
  -o ~/.claude/skills/claude-101-mastery.md

Done. Start a new Claude Code session and just talk na
