AI agents call analyze_figure to retrieve information from MATLAB MCP Tool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description, the name 'analyze_figure' most naturally aligns with inspection and retrieval of figure data rather than modification. The tool sits alongside other read-oriented tools (get_figure_metadata, get_plot_data, get_struct_info) in an interactive MATLAB environment. Analysis operations typically have no side effects on the underlying data.
From the tool's definition Tool name 'analyze_figure' combined with sibling tools 'get_figure_metadata' and 'get_plot_data' suggests data retrieval.
Documented attack patterns abuse exactly the kind of access analyze_figure gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MATLAB MCP Tool, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_figure:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_figure": {}
}
}analyze_figure is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

analyze_figure. It is categorised as a Read tool in the MATLAB MCP Tool MCP Server, which means it retrieves data without modifying state.
Register the MATLAB MCP Tool MCP server in PolicyLayer and add a rule for analyze_figure: 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 MATLAB MCP Tool. Nothing to install.
analyze_figure 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_figure 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_figure. 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.
analyze_figure is provided by the MATLAB MCP Tool MCP server (neuromechanist/matlab-mcp-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MATLAB MCP Tool, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
