Postgres MCP Hardened

Secure read-only PostgreSQL MCP server in Rust — a maintained alternative to the deprecated @modelcontextprotocol/server-postgres. Blocks writes at the AST, not with regexes.

Command execution is bounded: inventory; node child_process (scripts/run-tests.js:22); synchronous shell execution (scripts/run-tests.js:54); node child_process (lib/install.js:16); synchronous shell execution (lib/install.js:84); An inventory of where the code starts another program, not a verdict on this row: whether each one runs a fixed program or whatever it is handed takes a reading by hand.
Licence and provenance: finding; no LICENCE file at the root (.)
Data handling disclosed: finding; no statement of what it reads, writes or sends (README.md)

Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.

How far this has been checked

Static scanned

What it establishes: Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
What it does not: How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
Exactly what was read: Version 0.1.10, the file with digest sha512-XyggcZPOjzG7pFSvuNHP+jcN1qSrxMg5KWfJM68WCrWQs5sSl6sj0QsOd+1zyQz9n4eRFCP3nXVntLy0WXnoHw==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.

How the rungs work

Adding it

Its entry in the official MCP registry says the server is started with arguments this page cannot print without guessing, so there is no command here rather than one that would not start it. The maker's own instructions are at the source linked on this page.

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
