Common questions

Is Pgmoat safe?

It passed 2 of 2 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: PGMOAT_DATABASE_URL

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (0.1.2) reached the registry 4 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

pgmoat

Governed Postgres access for AI agents.

pgmoat is an open-source MCP server that gives AI agents read-only access to Postgres. It checks every query with the real Postgres parser, hides the tables and columns you mark hidden, applies row limits and timeouts, binds Row-Level Security to the caller's identity, and writes a tamper-evident audit log.

Requires Node.js 22.12 or newer and Postgres 15 to 18.

Quickstart

Run it against your database with safe defaults, no config file needed:

npx -y pgmoat postgresql://readonly_user:password@localhost:5432/mydb

Add it to Claude Code:

claude mcp add pgmoat -- npx -y pgmoat postgresql://readonly_user:password@localhost:5432/mydb

Or to Claude Desktop (claude_desktop_config.json):

"mcpServers": { "pgmoat": { "command": "npx", "args": ["-y", "pgmoat", "--url-env", "PGMOAT_DATABASE_URL"], "env": { "PGMOAT_DATABASE_URL": "postgresql://readonly_user:password@localhost:5432/mydb" } } } }

Passing the URL through --url-env keeps the password out of process listings.

Use a dedicated read-only role. pgmoat checks the role at startup. With a pgmoat.yaml, it refuses to start if the role is a superuser (PGM-701), has BYPASSRLS while row-level security is configured (PGM-702), or owns a protected table without FORCE ROW LEVEL SECURITY (PGM-703), unless you pass --allow-unsafe-role; every audit entry then records the override. In zero-config mode (a URL and no config file) it warns and continues.

Add descriptions and hide sensitive data

export PGMOAT_DATABASE_URL=postgresql://readonly_user:password@localhost:5432/mydb

npx pgmoat init # writes pgmoat.yaml; auto-hides columns like password_hash and token_hash npx pgmoat validate # checks the file against the schema and the database npx pgmoat doctor # checks the role for unsafe privileges npx pgmoat start # starts the server with ./pgmoat.yaml

A pgmoat.yaml looks like this:

version: 1

server: name: mydb connection: url: ${PGMOAT_DATABASE_URL} schemas: [public] mode: read-only budgets: max_rows: 200 max_query_ms: 5000 tables: users: description: "One row per login account" columns: password_hash: { hidden: true } email: { sensitive: high }

Commands

Command	What it does
`pgmoat`	Start with safe defaults (no config file)
`pgmoat init`	Create `pgmoat.yaml` from your database
`pgmoat start`	Start the MCP server from `pgmoat.yaml`
`pgmoat validate`	Check `pgmoat.yaml` against the schema and the database
`pgmoat doctor`	Check the database role for unsafe privileges
`pgmoat audit verify`	Verify the audit log hash chain
`pgmoat schema-export`	Write the visible schema as Markdown

Run pgmoat --help for all options.

What pgmoat does not do

It does not stop prompt injection. It removes the write path, hides what you mark hidden, and labels returned data as untrusted, but an agent with other tools (web access, email) can still be tricked into sending readable data elsewhere.
It does not replace Postgres permissions. The strongest control is a dedicated role with only the grants it needs.
It does not make RLS policies correct. It sets the session variables your policies read. A flawed policy stays flawed.
It does not guarantee audit delivery to a remote destination during an outage. It buffers, alarms, and records drops.
