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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00026 | $0.00494 |
| Opus 5 | $0.00013 | $0.00247 |
| Sonnet 5 | $0.00005 | $0.00099 |
| Haiku 4.5 | $0.00003 | $0.00049 |
Grade A, and why
mcp-audit scanned grade A with 0 findings 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 9d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
MCP Auditor (/mcp-audit)
Perform a thorough pre-implementation audit of connected Model Context Protocol (MCP) servers, available tools, local utility modules, and project dependencies before writing any code.
Usage
/mcp-audit <task_description>
Workflow Instructions
When invoked with a task description, follow these execution steps:
Step 1: Inspect Context & MCPs
- Audit Connected MCP Tools: Query and list all connected MCP servers, available MCP tools, and external integrations available in the environment.
- Audit Workspace Components: Inspect local workspace files, utility functions, libraries, schemas, and dependencies relevant to
<task_description>. - Analyze Reuse Opportunities: Identify overlaps between task requirements and existing components or tools.
Step 2: Generate Report
Output a structured Component & MCP Reuse Report following this format:
# Component & MCP Reuse Report
## Task Overview
[Summary of the task description]
## Reusable Components & MCP Tools
- **MCP Tools**: [List connected MCP tools relevant to this task]
- **Project Modules / APIs**: [List existing local files, modules, or functions]
## Gaps Requiring Custom Implementation
- [List features or components that must be built from scratch]
## Proposed Step-by-Step Strategy
1. [Step 1 leveraging existing tools/modules]
2. [Step 2...]
Step 3: Enforce Hard Stop & Decision Protocol
[!CRITICAL] STRICT ENFORCEMENT RULES:
- DO NOT modify any existing source code or configuration files during this phase.
- DO NOT create new code or resource files.
- DO NOT execute state-modifying shell or build commands.
- MUST NOT ask vague open-ended questions without structure.
- MUST use judgment to present next steps as a clean, structured choice tailored to the context complexity (1, 2, 3, or more choices).
- MUST always end choices with an
Other (specify)option.
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.

mcp-audit is a skill published in the GitHub repository roots-rs/mcp-auditor (0 stars, last pushed 1mo ago), licensed MIT. It adds 26 tokens to every session and 494 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
