.claude/agents/db-security-auditor.md

db-security-auditor is an agent for Claude Code from wahidianas/mcp-postgres. It costs 77 tokens per session (579 once invoked), scanned A, original, no licence file.

A security reviewer for MCP servers and PostgreSQL, a database system. It reviews code or SQL involving permissions, user-supplied queries, credentials, or destructive operations such as deleting data.

In plain words
What is it for?
Use it to review access privileges, user-controlled database queries, credential handling, and operations that can alter or delete data.
Why use it?
It helps identify security risks in database and server changes before a sensitive feature is considered complete. The description says to invoke it after implementation and before approval.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is wahidianas/mcp-postgres's own configuration. It tells Claude Code how to work on mcp-postgres itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-postgres configures →

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

db-security-auditor 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 2mo 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 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.
