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 servers
• mcp-audit – see which tools you actually use versus which waste tokens
• mcp-optimize – generate a project-local configuration with only what you need
• mcp-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.
