maskdb

maskdb is a read-only REST gateway that turns a Postgres database into a masked, structured query API for AI agents. List databases, tables, schemas, and indexes, then run structured (non-SQL) reads. Masked columns are returned masked and can never be used to filter or sort.

Official docs: https://github.com/e7h4n/maskdb

When to Use

Use this skill when you need to:

• Discover the databases, tables, columns, and indexes a token can reach
• Run safe, read-only structured queries against a Postgres database
• Read data without exposing sensitive columns (they come back masked)

Prerequisites

Connect the maskdb connector at app.vm0.ai/connectors.
