List all datasets in the project with pagination support.
AI agents call list_datasets to retrieve information from Langfuse 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 and enumerates datasets without creating, modifying, or deleting any data. It has no side effects beyond querying. The pagination support confirms it is a read-only query operation. Severity is low because listing datasets poses minimal risk even if misused by an agent — it only exposes metadata about existing datasets without exposing their contents or enabling any destructive actions.
From the tool's definition Tool name is 'list_datasets' and description states it 'List all datasets in the project with pagination support' — a pure retrieval operation with no modification, deletion, or execution of external systems.
Attacks that exploit this kind of access
List all datasets in the project with pagination support. It is categorised as a Read tool in the Langfuse MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Langfuse MCP Server MCP server in PolicyLayer and add a rule for list_datasets: 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 Server. Nothing to install.
list_datasets 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_datasets 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_datasets. 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_datasets is provided by the Langfuse MCP Server MCP server (therealsachin/langfuse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
