write = sends, deletes, buys or postsRead from the package source without running it. The installed server may list more.
analyze_serversScan your MCP config and measure the token cost of every installed server. Returns tool count, total tokens, and a grade (A-F) per server.
analyze_toolsGet detailed token cost breakdown for each tool in a specific MCP server. Shows per-tool grades, bloated descriptions, and optimization suggestions.
count_tokensCount the number of tokens in a piece of text. Useful for estimating context window usage.
find_duplicatesScan all MCP servers for duplicate or overlapping tool names. Helps identify redundant servers eating your context window.
generate_reportGenerate a comprehensive markdown health report for your MCP setup. Includes grades, token costs, duplicates, and optimization recommendations.

Install Checkup in Claude Code, Cursor or VS Code
Runs npx -y mcp-checkup on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says
From the Checkup repository's README, as published. We do not edit it. Read it on GitHub
mcp-checkup
Your MCP servers are eating your context window. Find out how much.
mcp-checkup is an MCP server that analyzes your MCP setup — measuring the token cost of every installed server and tool, finding duplicates, grading efficiency, and generating optimization reports.
Quick Start
npx mcp-checkupThen ask your AI assistant:
"Run an MCP health check on my setup"
"How many tokens are my MCP servers using?"
"Generate an MCP health report"Why?
Every MCP tool costs 550–1,400 tokens just for its schema. A server with 50 tools can eat 30,000+ tokens before you type anything. Most developers have no idea how much context window their MCP servers are consuming.
Real examples from the community:
- 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)
Tools
analyze_servers
Scan your MCP config and measure the token cost of every installed server. Auto-detects config files.
"Which of my MCP servers costs the most tokens?"analyze_tools
Deep-dive into a specific server — per-tool token costs, grades, bloated descriptions, and optimization suggestions.
"Break down the token cost of my GitHub MCP server"find_duplicates
Find duplicate tool names across your installed servers. Redundant tools waste context for no benefit.
"Do any of my MCP servers have overlapping tools?"count_tokens
Count tokens in any text. Useful for estimating context usage.
"How many tokens is this prompt?"generate_report
Full markdown health report: server grades (A-F), token costs, duplicates, and actionable recommendations.
"Generate a full MCP health report"Grading System

Installation
Claude Desktop / Claude Code
{
"mcpServers": {
"mcp-checkup": {
"command": "npx",
"args": ["-y", "mcp-checkup"]
}
}
}Cursor
Add to .cursor/mcp.json with the same format.
Auto-Detection
mcp-checkup automatically finds your MCP config in these locations:
- .mcp.json (current directory)
- Claude Desktop config (Windows/macOS/Linux)
- .cursor/mcp.json
Or pass a custom path to any tool.

Checkup: common questions
- Is Checkup MCP server safe?
- Mostly: it is graded B (82/100). Read the Checkup safety report
- How do I install Checkup?
- It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
- Does Checkup need an API key?
- Not as far as the registry entry and our scan can tell: no credentials are declared or required.
- Is Checkup maintained?
- The last commit was 205 days ago (2026-04-13). The latest release is v0.1.0.
- What can I use instead of Checkup?
- Servers from other publishers that do the same job: Entroly MCP server and Token Optimizer MCP server.
- How does Checkup compare with other MCP servers?
- safety score 82/100 (higher than 63% of 48,255 servers); tools 5 (the typical server has 7); tools that change things 0% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
