Return properties of a named magnetic material (iron, silicon_steel, ferrite, neodymium, mu_metal, air)
AI agents call material_lookup to retrieve information from Magnetics SME MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a static database of magnetic material properties (permeability, saturation, etc.) and returns information. It has no capability to modify data, execute arbitrary operations, delete resources, or cause financial impact. The operation is purely informational and retrieves existing material specifications used for engineering calculations.
From the tool's definition Tool name 'material_lookup' and description 'Return properties of a named magnetic material' indicates a read-only query operation that retrieves predefined material property data without modification or side effects.
Attacks that exploit this kind of access
Return properties of a named magnetic material (iron, silicon_steel, ferrite, neodymium, mu_metal, air). It is categorised as a Read tool in the Magnetics SME MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Magnetics SME MCP Server MCP server in PolicyLayer and add a rule for material_lookup: 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 Magnetics SME MCP Server. Nothing to install.
material_lookup 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 material_lookup 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 material_lookup. 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.
material_lookup is provided by the Magnetics SME MCP Server MCP server (jkearney126/maxwell_bot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
