Tools & Capabilities Breakdown

Db Conn MCP Tools (23)

list_databases

Configured databases (name, mode, yolo, and `active_port` when a fallback port is in use — **no DSN**).

list_tables

Tables and views in a database. Narrow it in the database rather than after the fact: `pattern` keeps only names containing it (fuzzy, case-insensitive) and `limit` caps the number of rows.

get_table_schema

Columns, types, primary/foreign keys for a table. Pass `include_indexes=true` to also get its indexes (`name`, key `columns` in index order — an INCLUDE payload is not listed — `unique`, `method`); omitted by default.

get_database_schema

The whole database's schema in one deterministic call. `format="json"` (default) returns every table's columns/types/PK/FK; `format="sql"` returns a **self-contained, runnable DDL script** (tables, sequences, PK/FK/UNIQUE/CHECK, indexes, trigger functions, triggers) — no extra tools required.
