List available brand collateral types (business cards, stationery, etc.)
AI agents call list_collateral_types to retrieve information from AI-Canvas MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries or retrieves a static list of collateral types—a read-only operation with no side effects. There is no data creation, modification, deletion, or code execution. The blast radius of misuse is minimal; an agent could only learn what collateral types exist in the system.
From the tool's definition Tool name 'list_collateral_types' and description 'List available brand collateral types' indicate retrieval and enumeration of predefined branding asset types without modification, deletion, or execution of code.

list_collateral_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_collateral_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.
