AI agents call db_queue to retrieve information from Atlas without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves queue status information with no side effects. It is a read-only operation similar to a status check or monitoring query. The verb 'Get' confirms data retrieval without modification, creation, or deletion. In a clinical document system, accessing queue status poses minimal security risk as it only exposes operational metadata.
From the tool's definition Tool name 'db_queue' and description 'Get ingestion queue status' indicate a retrieval operation that queries the status of an ingestion queue without modifying any data.
Attacks that exploit this kind of access
Get ingestion queue status. It is categorised as a Read tool in the Atlas MCP Server, which means it retrieves data without modifying state.
Register the Atlas MCP server in PolicyLayer and add a rule for db_queue: 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 Atlas. Nothing to install.
db_queue 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 db_queue 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 db_queue. 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.
db_queue is provided by the Atlas MCP server (rsanandres/atlas_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
