PGSandbox: A Postgres Sandbox for Coding Agents
An open-source local Postgres MCP server that gives coding agents isolated, disposable databases for migrations, SQL testing, and backend bug reproduction.
- For
- Developers testing agent-written Postgres changes
- Worth noticing
- Each task receives a temporary database, restricted login role, expiry time, and tracked cleanup workflow.
Field notes
The project separates lifecycle access from query access: administrative connections manage databases while agent SQL uses a restricted role. Its local runtime uses a separate data directory and high port rather than taking over the conventional 5432 port. The homepage also describes row and result bounds, positive TTLs, and ownership metadata intended to contain experiments, while linking to installation documentation, GitHub, a blog, and a changelog.
