List all triggers for a table
AI agents call postgres_list_triggers to retrieve information from Multi-Database MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about database triggers, which is a read-only operation with no side effects. It queries the database schema to enumerate triggers associated with a table, analogous to a LIST or GET operation. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal since the output is informational only.
From the tool's definition Tool name contains 'list' and description states 'List all triggers for a table' — a query operation that retrieves metadata without modification
Attacks that exploit this kind of access
List all triggers for a table. It is categorised as a Read tool in the Multi-Database MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Multi-Database MCP Server MCP server in PolicyLayer and add a rule for postgres_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 Multi-Database MCP Server. Nothing to install.
postgres_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 postgres_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 postgres_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.
postgres_list_triggers is provided by the Multi-Database MCP Server MCP server (nam088/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
