AI agents call get_brand to retrieve information from Canva API 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 brand information without modifying or deleting data. It follows the naming convention of other read-only tools on the server (get_asset, get_design, get_user) and poses minimal risk if misused by an AI agent—at worst, it exposes brand metadata the agent is already authorized to access.
From the tool's definition Tool name 'get_brand' suggests retrieval of brand data. The sibling tools include read-only operations like 'get_asset', 'get_design', 'get_user', and 'list_*' variants, establishing a pattern where 'get_' prefixed tools are retrievals without side effects.
Documented attack patterns abuse exactly the kind of access get_brand gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Canva API MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_brand:
{
"version": "1",
"default": "deny",
"tools": {
"get_brand": {}
}
}get_brand is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
