Schema-driven generator for **safe, scoped PostgreSQL DML tools** in
[FastMCP](https://github.com/jlowin/fastmcp) agent systems.

Point it at a PostgreSQL database and it introspects the schema and generates one
typed MCP tool per DML operation per table — `insert`, `select`, `update`,
`delete`, plus optional `select_joined`. The agent gets exactly those tools and
nothing else: no raw SQL, no schema changes, no access to tables you didn't
expose.

## Why

Giving an agent database access usually means choosing between read-only access
or risking that the agent runs arbitrary SQL and changes data or settings you
never intended. This project gives you a controlled middle ground: a fixed set
of generated, validated, parameterized tools scoped to the tables and operations
you choose.

## What it does

- Introspects your schema (tables, columns, types, foreign keys, `pgvector`).
- Generates a FastMCP tool per DML operation per table, each with a dedicated
  Pydantic input model derived from the table.
- Supports rich, **injection-safe** filtering (`WhereFilter`) and ordering,
  including vector KNN search.
- Excludes chosen columns from generated tool inputs (e.g. `id`, `created_at`).
- Exposes only the generated tools — never raw SQL or DDL.

## Security model

> [!IMPORTANT]
> The generated tool layer controls *which operations exist*; the PostgreSQL
> role you connect as controls *what those operations can physically do*.
> **Connect as a dedicated least-privilege role, never a superuser.**
> Read [SECURITY.md](SECURITY.md) before deploying.

- Filter/order field names are validated against real columns and emitted…
