MCP Sprawl Audit

Audit MCP server sprawl on this machine for Claude Code, Codex CLI and Grok CLI. Counts how many copies of each MCP server the running agent sessions hold, what they cost in memory, which ones are duplicates, unused, unpinned or bundled in plugins, and which can run as one shared HTTP copy instead. Use when the machine is slow with many agent sessions open, when someone asks how much memory MCP servers use, or before adding more MCP servers. Read-only; it writes a plan and changes nothing.

# MCP sprawl audit

Each agent session starts its own copy of every local (stdio) MCP server in its config.
Fifty sessions means fifty copies, plus an idle npx or uvx launcher above each one. This
skill measures that and proposes a plan. It never edits a config, starts or stops a
process, or prints a secret value. From a command line it prints only a package name or a
script's file name.

## 1. Run the audit

```sh
python3 <this skill's folder>/scripts/audit.py          # Markdown report
python3 <this skill's folder>/scripts/audit.py --json   # the same data, structured
```

Python 3.11 or newer reads every config. On older Python, Codex and Grok servers that
exist only in their `config.toml` are missed, and the script says so. Reading 30 days of
session logs takes a few seconds; `--no-usage` skips it, `--days N` changes the window.

What it reads, all locally:

| Agent | Config | Usage (tool calls per session) |
|---|---|---|
| Claude Code | `~/.claude.json` (user and local scope), each project's `.mcp.json`, enabled plugins, managed-mcp.json | `~/.claude/projects/**/*.jsonl` |
| Codex CLI | `codex mcp list --json` (includes plugin servers), else `~/.codex/config.toml` | `~/.codex/sessions/**/*.jsonl` |
| Grok CLI | `~/.grok/config.toml` and project ones, then Claude's, Cursor's and the project `.mcp.json`, which Grok loads by default | `~/.grok/sessions/**/updates.jsonl` |

Processes come from `ps`. A copy is a process an agent started that matches a configured
