Analyzes Claude Code session history to identify and eliminate token waste from underutilized MCP servers.
The mcp-audit skill provides a diagnostic layer for your Claude Code environment by scanning your session history to reveal exactly how many tokens are being consumed by idle MCP tool schemas. It ranks your servers by cost and usage frequency, offering actionable insights on whether to restrict server scope to specific projects or convert high-waste tools into on-demand skills. This ensures a leaner, faster, and more cost-effective development workflow by preventing Claude from loading unnecessary context in every turn.
