analyze_portfolio_correlation
AI agents call analyze_portfolio_correlation to retrieve information from IB Analytics MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears designed to compute and return correlation metrics across portfolio positions. This is a read-only analytical operation that retrieves and processes existing data without creating, modifying, deleting, or executing external operations. The empty description slightly reduces confidence, but the naming pattern and server purpose (analytics/reporting) strongly suggest passive data analysis.
From the tool's definition Tool name 'analyze_portfolio_correlation' combined with server context showing analysis tools (analyze_bonds, analyze_performance, analyze_risk, etc.) indicates data retrieval and computation rather than modification. Description is empty, limiting certainty.

Register the IB Analytics MCP Server MCP server in PolicyLayer and add a rule for analyze_portfolio_correlation: 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 IB Analytics MCP Server. Nothing to install.
analyze_portfolio_correlation 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 analyze_portfolio_correlation 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 analyze_portfolio_correlation. 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.
