Get a summary of total cost, tokens, and traces for a project over a time window.
AI agents call project_overview 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 queries and returns analytics data about project usage and costs. It has no side effects, does not execute code or external operations, does not modify or delete data, and does not move money. It is purely informational retrieval. The low severity reflects minimal risk even if misused by an AI agent—it only exposes read-only project metrics that would typically already be visible to authorized users.
From the tool's definition Tool retrieves summary metrics (cost, tokens, traces) without modifying data. Description uses 'Get' verb indicating query/retrieval. No creation, modification, deletion, or execution indicated.
Attacks that exploit this kind of access
Get a summary of total cost, tokens, and traces for a project over a time window. 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 project_overview: 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.
project_overview 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 project_overview 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 project_overview. 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.
project_overview 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.
