mcp-optimizer reduces token waste from idle MCP servers in Claude Code
mcp-optimizer is a plugin that addresses token waste in Claude Code when using Model Context Protocol (MCP) servers. The problem: every connected MCP server loads its full tool schema into every conversation, even if tools are never used. With three servers, this can waste approximately 6,500+ tokens per session.
Key features
mcp-doctor– health check your MCP serversmcp-audit– see which tools you actually use versus which waste tokensmcp-optimize– generate a project-local configuration with only what you needmcp-to-skills– convert MCP tools into on-demand local Skills (zero idle cost)
The core concept: Skills only load when invoked, while MCP schemas load every time. This optimization reduces unnecessary token consumption.
Installation
Install via the plugin marketplace:
/plugin marketplace add choam2426/mcp-optimizer
/plugin install mcp-optimizerThe plugin is available on GitHub at https://github.com/choam2426/mcp-optimizer.
