security-audit

A repository-wide security review that examines authentication, permissions, input handling, data protection, APIs, dependencies, and common vulnerability patterns.

In plain words
What is it for?
Use it for a security audit, compliance review, or vulnerability assessment of an entire codebase.
Why use it?
It helps locate security weaknesses and shows how security-sensitive code connects across the system.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 184 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

security-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 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.

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

Complete Security Audit

Perform a comprehensive security analysis of the entire repository.

This command conducts a full security audit by:

  1. Identifying all authentication and authorization patterns
  2. Finding data validation and sanitization throughout the codebase
  3. Analyzing all API endpoints and their security measures
  4. Mapping security-related dependencies across the system
  5. Checking for common vulnerability patterns

Follow these steps:

  1. Use nodes-semantic-search with security-related queries (auth, validation, sanitization, encryption, password, token)
  2. Get implementation details of all security-critical functions with get-code
  3. Analyze security dependencies with get-usage-dependency-links
  4. Find security flow connections with find-direct-connections
  5. Search for security documentation with docs-semantic-search
  6. Generate a comprehensive security report with recommendations

This command is ideal for: security audits, compliance checks, and vulnerability assessments.

Changes

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.

security-audit is a command published in the GitHub repository diffbot/mcp-code-graph (402 stars, last pushed 9mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 184 tokens. 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 2026-08-30.
