## MCP tools (7)

### `list_connections` (~19 tokens)

List all available SQL Server connections grouped by connectionGroup

### `reload_connections` (~30 tokens)

Reload connections from connections.json file without restarting the MCP server. Closes existing connection pools and loads new configuration.

### `query` (~156 tokens)

Execute a SQL query on the database

Input parameters:

- `connection` (string, required): Connection name to use
- `format` (string): Output format (default json). csv is far more compact for wide or long results: the first line is a JSON header with metadata, then the rows as CSV.
- `maxRows` (integer): Maximum rows to return across all result sets (default 1000, max 10000). When the cap is hit the query is cancelled on the server and the response starts with truncated: true. A truncated result is i…
- `sql` (string, required): SQL query to execute

### `get_schema` (~44 tokens)
