List all asset collections in the current project
AI agents call list_collections 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 retrieves information about existing asset collections without creating, modifying, or deleting any data. It is a straightforward query operation that poses minimal risk—an AI agent misusing it would only have access to view metadata about assets already in the project. No side effects or state changes occur.
From the tool's definition Tool name 'list_collections' and description 'List all asset collections in the current project' indicate a retrieval operation with no modification of data.
Attacks that exploit this kind of access
List all asset collections in the current project. It is categorised as a Read tool in the AI-Canvas MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AI-Canvas MCP Server MCP server in PolicyLayer and add a rule for list_collections: 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 AI-Canvas MCP Server. Nothing to install.
list_collections 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_collections 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_collections. 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_collections is provided by the AI-Canvas MCP Server MCP server (laoluojuhai/ai-canvas). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
