AI agents call list_triggers to retrieve information from Mssql without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
schema | string | — | Schema name (default: dbo) |
tableName | string | — | Filter by specific table name |
connectionName | string | — | Named connection to use (e.g., 'production', 'staging') |
connectionString | string | — | SQL Server connection string (uses default if not provided) |
Parameters from the server's own tool schema.
This tool performs a schema discovery operation—it retrieves and enumerates trigger definitions from the database. There are no side effects, no code execution, no data modification, and no deletion. It is purely informational, similar to the sibling tools 'describe_table', 'describe_view', and 'describe_stored_procedure'.
From the tool's definition Tool name 'list_triggers' and description 'List all triggers in the database' indicate a retrieval operation that returns metadata about triggers without modifying or executing anything.
Attacks that exploit this kind of access
List all triggers in the database with their associated tables. It is categorised as a Read tool in the Mssql MCP Server, which means it retrieves data without modifying state.
list_triggers accepts 4 parameters: schema, tableName, connectionName, connectionString. The full parameter table on this page comes from the server's own tool schema.
Register the Mssql MCP server in PolicyLayer and add a rule for list_triggers: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mssql. Nothing to install.
list_triggers is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_triggers rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_triggers. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_triggers is provided by the Mssql MCP server (mssql-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
