Pgvouch

shubh_sgr · MCP server

Connects an AI assistant to PostgreSQL migration checks through seven read-only tools, and also works from the terminal. It compares a source and a target database for schema drift, verifies data with row checksums, and analyses which locks each statement in a migration needs. It suggests rewrites such as concurrent index builds, tags steps as reversible or data-lossy and generates rollback SQL. An optional language model, off by default, only proposes plans; a parser, rules and a shadow run decide.

Written by ooruby from the README of pgvouch 0.4.4.

Not claimed by its maker. Is this yours? Prove it and answer the findings

Why it's useful

Your agent can check a Postgres migration for drift and lock impact before it runs, with pass or fail decided by rules rather than by the model.

What you could do with it

  1. 1Compare a source and a target database and list the schema differences between them.
  2. 2Run a migration file through the lock analyser to see the lock impact of each statement.
  3. 3Check before a deploy whether a migration would have to wait for locks right now on the live database.

Written from its documentation: what it says it can do, not what our checks found.

Maintenance

Not measured

No release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.

Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured

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 0.4.4, the file with digest sha512-CgEJGVmc1eld5lOjQIUrCtkxXBrywAlOYfH9kmt/e4FezYagI1gpHZ3z/QPAaXEl3seVJ8K9Wyj+0zz3icuegg==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
Authentication
Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
How the rungs work

Adding it

Paste this into your client's MCP configuration.

{
  "mcpServers": {
    "pgvouch": {
      "command": "npx",
      "args": [
        "-y",
        "pgvouch@0.4.4"
      ]
    }
  }
}

Or run it directly.

npx -y pgvouch@0.4.4

Pinned to 0.4.4, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

The badge, if this is your listing

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.
