Generate correlation matrix heatmap and return/save both matrix and image.
AI agents call generate_correlation_matrix to retrieve information from Vibe Preprocessing and Analysis MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs statistical analysis (correlation matrix) and visualization on existing data. While it may save output files, its primary purpose is reading/analyzing data and generating a heatmap. The save operation is a minor side effect of a fundamentally read/analytical operation. Severity is low as misuse would at most overwrite an output file.

Attacks that exploit this kind of access
Generate correlation matrix heatmap and return/save both matrix and image. It is categorised as a Read tool in the Vibe Preprocessing and Analysis MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Vibe Preprocessing and Analysis MCP Server MCP server in PolicyLayer and add a rule for generate_correlation_matrix: 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 Vibe Preprocessing and Analysis MCP Server. Nothing to install.
generate_correlation_matrix 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 generate_correlation_matrix 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 generate_correlation_matrix. 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.
generate_correlation_matrix is provided by the Vibe Preprocessing and Analysis MCP Server MCP server (mudit14224/vibe-data-analysis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
