Plots multiple functions on the same graph.
AI agents call plot_multiple_functions to retrieve information from Desmos MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and visualizes mathematical function data through graphical rendering. It performs a read-only operation that generates visual output without creating, modifying, deleting, or destructively altering any underlying data. No code execution, financial transactions, or irreversible operations are involved.
From the tool's definition Tool name 'plot_multiple_functions' and description 'Plots multiple functions on the same graph' indicate visualization/rendering of mathematical data with no data modification, deletion, or external side effects.
Documented attack patterns abuse exactly the kind of access plot_multiple_functions gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Desmos MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for plot_multiple_functions:
{
"version": "1",
"default": "deny",
"tools": {
"plot_multiple_functions": {}
}
}plot_multiple_functions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Plots multiple functions on the same graph. It is categorised as a Read tool in the Desmos MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Desmos MCP Server MCP server in PolicyLayer and add a rule for plot_multiple_functions: 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 Desmos MCP Server. Nothing to install.
plot_multiple_functions 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 plot_multiple_functions 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 plot_multiple_functions. 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.
plot_multiple_functions is provided by the Desmos MCP Server MCP server (thegrsun/desmos-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Desmos MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
