Look up material properties for injection molding simulation. Returns Cross-WLF viscosity model, 2-domain Tait PVT, thermal properties, processing window, and mechanical data. Available materials: ${listMaterials().map(m => m.id).join(
AI agents call get_material_properties to retrieve information from Moldsim mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a lookup operation that queries and retrieves material property data for injection molding simulations. It has no side effects, does not modify or delete data, and does not execute code or trigger external operations. This is a straightforward Read operation with low risk if an AI agent uses it, as the worst case is irrelevant or noisy retrieved data.
From the tool's definition Tool name 'get_material_properties' and description 'Look up material properties' indicate data retrieval.
Attacks that exploit this kind of access
Look up material properties for injection molding simulation. Returns Cross-WLF viscosity model, 2-domain Tait PVT, thermal properties, processing window, and mechanical data. Available materials: ${listMaterials().map(m => m.id).join(. It is categorised as a Read tool in the Moldsim mcp MCP Server, which means it retrieves data without modifying state.
Register the Moldsim MCP server in PolicyLayer and add a rule for get_material_properties: 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 Moldsim mcp. Nothing to install.
get_material_properties 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 get_material_properties 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 get_material_properties. 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.
get_material_properties is provided by the Moldsim MCP server (moldsim/moldsim-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
