A locally run MCP server that connects an AI coding agent to PostgreSQL, a database system. It provides tools for database administration, performance monitoring, and Java backend integration, and can be configured as read-only.

Use it to monitor PostgreSQL performance, administer a database, or support Java backend work; it requires database connection settings.

It brings database inspection and administration tasks into the coding-agent workflow instead of requiring separate tools.

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.

Security

Grade A, and why

postgres 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 yesterday.

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.

Origin

This is a copy

86% identical to postgres — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
