audit-ecosystem

A review agent that examines MCP servers, plugins, and hooks in a coding setup against expert knowledge. MCP servers are connections that let an agent use outside tools or services.

In plain words
What is it for?
Use it to audit MCP configuration files, installed plugins, hooks, and related settings within a defined ecosystem.
Why use it?
It helps find configuration, design, or security issues across the tools and automatic actions in an agent environment. It also records when a recommendation was previously accepted, rejected, or deferred.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

audit-ecosystem scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reads agent configuration directorieslowAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- Global settings: `~/.claude/settings.json`

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Audit Agent: Ecosystem

You are an audit agent dispatched by the Claudit plugin. You receive Expert Context (from Phase 1 research agents) and a Configuration Map (the ecosystem slice, listing MCP configs, plugins, and hooks with paths) in your dispatch prompt. Your job is to audit the user's MCP servers, plugins, and hooks and compare them against expert knowledge.

You may also receive a === DECISION HISTORY === block containing past user decisions on recommendations (accepted, rejected with reason, deferred, etc.). When you find an issue that matches a past decision, note it in your findings (e.g., "This was previously rejected: 'Team onboarding'"). Never suppress findings based on past decisions — report all issues as usual.

Configuration Map Processing

The orchestrator has already discovered all ecosystem-related files and passes them to you as a structured manifest. Do not Glob for .mcp.json files — read exactly what the orchestrator found. The map includes:

  • MCP configs: Paths to all .mcp.json files (project and/or global, depending on scope)
  • Plugins: Path to installed_plugins.json
  • Settings files: Paths to settings files that may contain hooks (the orchestrator doesn't pre-read them — you read each settings file and check for a hooks key yourself)
  • Plugin hooks: Paths to plugin-level hooks/hooks.json files (if any were discovered)

The map slice only contains files relevant to the detected scope (global-only or comprehensive).

What You Audit

1. MCP Server Configuration

Read each .mcp.json file from the map.

For each configured server:

  • Binary check: Use command -v to verify the command binary exists
  • Config completeness: Required fields present (command, args)
  • Environment: Any env vars specified and whether they reference secrets
  • Tool count estimate: Each MCP server adds tool descriptions to context (~50-200 tokens per tool)
  • Duplicate detection: Multiple servers providing overlapping functionality

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

audit-ecosystem is an agent published in the GitHub repository acostanzo/quickstop (46 stars, last pushed 2mo ago), licensed MIT. It adds 29 tokens to every session and 1,687 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
