MCP Tool Auditor

Audit any MCP tool description for LLM reliability. Detect smells, scores quality 0-100, and rewrite for better agent accuracy.

Zero external APIs. Pure computation. Built for developers who care about agent reliability.

Why this exists

Research in 2026 shows that 97% of MCP tool descriptions contain at least one "smell" (vague purpose, missing usage guidelines, opaque parameters). When descriptions are weak, AI agents pick the wrong tool or waste steps.

This MCP server lets you (or your agent) audit and fix those descriptions before you publish.

Quick start

# Install & run with any MCP client
npx -y mcpize connect @princeruhulofficial/tool-auditor --client claude

Or add to your Claude / Cursor / other client config:

{
  "mcpServers": {
    "tool-auditor": {
      "command": "npx",
      "args": ["-y", "mcp-tool-auditor"]
    }
  }
}

Tools

Tool	What it does
audit_tool	Score one tool description (0-100), list smells, give fix suggestions
rewrite_tool_description	Generate a high-quality rewritten description ready to paste
audit_tool_list	Audit a full list of tools — detect overcrowding + rank quality
get_best_practices	Return the current best-practice checklist for MCP tool descriptions

Why entrepreneurs care

If you are building AI products or selling MCP servers:

• Agents that pick the wrong tool = wasted tokens + angry users
• High-quality tool descriptions = higher task success rate
• This server is free to run (no API bills) and can be called by your own agents during development

Pricing (when published on MCPize)

• Free: 100 audits / day
• Pro $9/mo: 2 000 audits / day

Development
