## MCP tools (5)

### `query_table` (~88 tokens)

Query rows from a database table with optional filters. All results pass through the KVKK/GDPR gateway — sensitive fields are automatically masked.

Input parameters:

- `filter` (object): Key-value filter pairs, e.g. { status: 'active' }
- `limit` (integer): Max rows to fetch before gateway limit is applied (default 50)
- `table` (string, required): Table name to query

### `list_tables` (~26 tokens)

List all available database tables. Tables marked as 'deny' in gateway policy are omitted.

### `describe_table` (~40 tokens)

Get the column names and gateway masking policy for a table — helps the LLM understand what data it can access.

Input parameters:

- `table` (string, required): Table name

### `query_audit_log` (~170 tokens)

Query the gateway's own audit log — inspect which tools were called, on which tables, whether they were allowed or denied (and why), and which fields were redacted/written. Covers events since this server process started; count is capped by the gateway's audit.bufferSize (default 200).

Input parameters:

- `deniedOnly` (boolean): Only return calls the gateway denied/blocked
- `limit` (integer): Max events to return, most recent first (default 50)
- `operation` (string): Filter by operation type
- `since` (string): ISO 8601 timestamp — only events at or after this time
- `table` (string): Filter by table name
- `tool` (string): Filter by MCP tool name, e.g. 'query_table', 'update_row'

### `gateway_status` (~25 tokens)

Show the active gateway configuration: field masking rules, table policies, and audit settings.
