Mcp Audit

This analyzes your active MCP servers and calculates how much token overhead each one adds to every single API request. The insight here is simple but easy to miss: a server with 20 tools burns 2-4K tokens per request whether you use those tools or not. Run this when sessions feel sluggish or before adding new servers. It counts tools per server, checks which ones you actually use, identifies overlaps, and recommends what to disable. The output includes estimated savings in both tokens and dollars. Good for anyone running more than a handful of MCP servers who wants to understand why their context window fills up faster than expected.

MCP Audit

Analyze MCP server overhead and recommend cleanup.

Trigger

Use when:

Sessions feel slow or expensive
Adding a new MCP server
Context fills up quickly
Reviewing project configuration

Key Insight

Each MCP server adds ALL its tool descriptions to every API request. A server with 20 tools adds ~2K-4K tokens per request, regardless of whether you use those tools.

Audit Steps

Step 1: List Active Servers

Check all MCP configurations:

cat .claude/settings.json 2>/dev/null | grep -A 50 "mcpServers"
cat ~/.claude/settings.json 2>/dev/null | grep -A 50 "mcpServers"

Step 2: Count Tools Per Server

For each server, estimate token overhead:

1-5 tools: ~200-500 tokens (low overhead)
6-15 tools: ~500-1500 tokens (moderate)
16-30 tools: ~1500-3000 tokens (high)
30+ tools: ~3000+ tokens (excessive — consider tool filtering)

Step 3: Check Usage

Questions to ask:

Which servers were actually used this session?
Which servers haven't been used in 7+ days?
Are there servers with overlapping functionality?
Are there servers only needed for specific tasks?

Step 4: Recommend Actions
