list_trigger_types
AI agents call list_trigger_types to retrieve information from Fuul MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to enumerate or retrieve available trigger types without modifying, executing, or deleting data. Sibling tools like 'create_trigger' and 'delete_trigger' are distinct, confirming this is a read operation. Empty description lowers confidence slightly, but the naming pattern is unambiguous.
From the tool's definition Tool name 'list_trigger_types' indicates a listing/retrieval operation with no modification capability. The 'list' prefix is a standard pattern for read-only queries. Description is empty, but naming convention strongly suggests data retrieval.

Register the Fuul MCP Server MCP server in PolicyLayer and add a rule for list_trigger_types: 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 Fuul MCP Server. Nothing to install.
list_trigger_types 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_trigger_types 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_trigger_types. 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.
