compute_correlations
AI agents call compute_correlations to retrieve information from Sablier MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Computing correlations is a read-only analytical operation on existing financial data. No modification, deletion, execution of external commands, or financial transactions are implied. The empty description reduces confidence slightly, but the name and server context strongly suggest statistical computation over a dataset.
From the tool's definition Tool name 'compute_correlations' indicates mathematical analysis without data modification. Context from sibling tools (analyze_quantitative, analyze_derivatives, backtest_rules) and server description (analyze portfolios, stress-test scenarios) all indicate…
Attacks that exploit this kind of access
compute_correlations. It is categorised as a Read tool in the Sablier MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sablier MCP Server MCP server in PolicyLayer and add a rule for compute_correlations: 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 Sablier MCP Server. Nothing to install.
compute_correlations 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 compute_correlations 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 compute_correlations. 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.
compute_correlations is provided by the Sablier MCP Server MCP server (sablier-ai/sablier-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
