Build a Query Builder request for incremental sync windows (find assets modified between timestamps).
AI agents call aem_search_query_builder_delta_window to retrieve information from Adobe Experience Assets Dev MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves or queries data about assets based on modification timestamps—a classic Read operation. It has no side effects and cannot create, modify, or delete data.
From the tool's definition Tool description states it builds a query to "find assets modified between timestamps" for "incremental sync windows." This is a search/query operation with no modification capability.
Attacks that exploit this kind of access
Build a Query Builder request for incremental sync windows (find assets modified between timestamps). It is categorised as a Read tool in the Adobe Experience Assets Dev MCP MCP Server, which means it retrieves data without modifying state.
Register the Adobe Experience Assets Dev MCP server in PolicyLayer and add a rule for aem_search_query_builder_delta_window: 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 Adobe Experience Assets Dev MCP. Nothing to install.
aem_search_query_builder_delta_window 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 aem_search_query_builder_delta_window 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 aem_search_query_builder_delta_window. 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.
aem_search_query_builder_delta_window is provided by the Adobe Experience Assets Dev MCP server (stubbedev/adobe-experience-dev-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
