PostgreSQL

Not in the app yet. The reference Postgres server is no longer maintained, so this waits for a first-party one — or for Gantry to ship its own. Everything below is what it will do when it lands. Meanwhile you can add any MCP server yourself under Settings → Connectors, and saying you want this one moves it up the list.

Point it at a connection string and the agent can explore the schema and run queries. Read-only by default; writes are a separate, explicit setting.

What it can do

Examples of the tools the agent gets from this connector. Each call shows up in the activity feed with its input and result.

1. postgresqllist_schemas
2. postgresqldescribe_table orders
3. postgresqlquery select …
4. postgresqlexplain analyze …

How it connects

Sign-in

Connection string you provide. You enter a connection string in the connector's settings. It is stored encrypted with the key in your OS keychain.

Runs as

MCP server run locally on your machine. An MCP server that runs as a local process on the Node or Python you already have. Gantry checks the runtime is present before installing.

Permissions

Reads run in every mode. Writes outside your folders, messages and anything destructive follow the chat's permission mode: they ask in Manual and Auto-edit, and are judged by the guard model in Auto. How permissions work

How it will install

1. 1

   Open Connectors in the sidebar. The catalog ships with the app; nothing is downloaded until you ask.

2. 2

   Find PostgreSQL and choose Install. Enter the connection string when asked.

3. 3

   Attach it to a chat, or leave it available to every chat in a project. The agent sees its tools from then on.
