What is the MCP Checkup MCP Server?

MCP server that analyzes your MCP setup: token costs, bloated schemas, duplicate tools, and optimization tips

What it actually does

Your MCP servers are eating your context window. Find out how much.

  • Adding GitHub MCP increased one user's token usage from 34K to 80K (source)
  • One developer found 67,000 tokens consumed by just 4 servers before any conversation (source)
  • Context7 (240K weekly downloads) has tool descriptions costing 3x more tokens than necessary (source)

Recorded tools

  • analyze_servers — Scan your MCP config and measure the token cost of every installed server. Auto-detects config files.
  • analyze_tools — Deep-dive into a specific server — per-tool token costs, grades, bloated descriptions, and optimization suggestions.
  • find_duplicates — Find duplicate tool names across your installed servers. Redundant tools waste context for no benefit.
  • count_tokens — Count tokens in any text. Useful for estimating context usage.
  • generate_report — Full markdown health report: server grades (A-F), token costs, duplicates, and actionable recommendations.
