MCP server that analyzes your MCP setup: token costs, bloated schemas, duplicate tools, and optimization tips
MCP server that analyzes your MCP setup: token costs, bloated schemas, duplicate tools, and optimization tips. The mcp checkup mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 6 defined tools rather than through you.
Your MCP servers are eating your context window. Find out how much.
mcp-checkup on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Everything the assistant can do here goes through one of these:
analyze_servers — Scan your MCP config and measure the token cost of every installed server. Auto-detects config filesanalyze_tools — Deep-dive into a specific server — per-tool token costs, grades, bloated descriptions, and optimization suggestionsfind_duplicates — Find duplicate tool names across your installed servers. Redundant tools waste context for no benefitcount_tokens — Count tokens in any text. Useful for estimating context usagegenerate_report — Full markdown health report: server grades (A-F), token costs, duplicates, and actionable recommendationsCursor — The Cursor tool exposed by this serverPlenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MCP Checkup's toolset — analyze_servers, analyze_tools, find_duplicates and 3 more — is a fair guide to whether it matches your workflow. It is maintained by yifanyifan897645; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
