postgres

postgres is an MCP server for Cursor from Byron2306/EdgeK-BEAST. Its token cost is not measured, scanned A, original, MIT.

A read-only connection to a PostgreSQL database, a system for storing structured application data. It lets the agent inspect the database structure and run SQL queries without changing data.

In plain words
What is it for?
Use it to inspect tables and relationships, investigate stored data, and answer questions with read-only SQL.
Why use it?
It avoids manually opening database tools or writing exploratory queries yourself, while protecting the database from edits.

MCP server for Cursor

Written for Cursor: installed under .cursor/. Also seen: listed in .cursor/mcp.json.

One of 10 entries in mcp.json upstream. Installing this one merges just its entry into your config; the other 9 are separate, each on its own page.

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 7d 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.

This page is one entry in a file that holds 10. Installing the file brings all of them; each is measured and scanned on its own page.

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.
