Get items in an annotation queue.
AI agents call get_queue_items to retrieve information from Langfuse Mcp Python without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves items from an annotation queue for viewing/monitoring purposes. There are no side effects, modifications, or destructive operations. It falls squarely within the Read category as it only accesses data without altering state.
From the tool's definition Tool name 'get_queue_items' and description 'Get items in an annotation queue' clearly indicate a retrieval operation. The verb 'Get' is a read-only action that queries existing data without modification, creation, or deletion.
Attacks that exploit this kind of access
Get items in an annotation queue. It is categorised as a Read tool in the Langfuse Mcp Python MCP Server, which means it retrieves data without modifying state.
Register the Langfuse Mcp Python MCP server in PolicyLayer and add a rule for get_queue_items: 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 Langfuse Mcp Python. Nothing to install.
get_queue_items 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 get_queue_items 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 get_queue_items. 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.
get_queue_items is provided by the Langfuse Mcp Python MCP server (log-logn/langfuse-mcp-python). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
