List all runs for a specific dataset.
AI agents call listDatasetRuns to retrieve information from Langfuse Mcp Extended without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing data (dataset runs) without side effects. It matches the Read category profile: no creation, modification, deletion, or execution of operations. The blast radius of misuse is minimal since it only exposes existing run information.
From the tool's definition Tool name contains 'list' and description states 'List all runs for a specific dataset' — pure retrieval with no modification, deletion, or execution of code/commands.
Attacks that exploit this kind of access
List all runs for a specific dataset. It is categorised as a Read tool in the Langfuse Mcp Extended MCP Server, which means it retrieves data without modifying state.
Register the Langfuse Mcp Extended MCP server in PolicyLayer and add a rule for listDatasetRuns: 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 Extended. Nothing to install.
listDatasetRuns 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 listDatasetRuns 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 listDatasetRuns. 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.
listDatasetRuns is provided by the Langfuse Mcp Extended MCP server (langfuse-mcp-extended). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
