Why OpenLCA_Impact_Assessment_Tool needs a policy

This tool runs a life cycle impact assessment calculation using OpenLCA, an external application. It executes a computational process with external side effects (invoking OpenLCA's calculation engine), placing it in the Execute category. The severity is high because misconfigured inputs could produce misleading environmental impact results used in consequential decisions, and it interacts with an external system.

From the tool's definition "Calculate life cycle impact assessment using OpenLCA" — triggers an external computation/execution within the OpenLCA application

POLICY

How to control OpenLCA_Impact_Assessment_Tool

PolicyLayer is an MCP gateway — it sits between your AI agents and TianGong-LCA-MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for OpenLCA_Impact_Assessment_Tool:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "OpenLCA_Impact_Assessment_Tool": {
      "limits": [
        {
          "counter": "openlca_impact_assessment_tool_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

OpenLCA_Impact_Assessment_Tool stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register TianGong-LCA-MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about OpenLCA_Impact_Assessment_Tool

What does the OpenLCA_Impact_Assessment_Tool tool do? +

Calculate life cycle impact assessment using OpenLCA. It is categorised as a Execute tool in the TianGong-LCA-MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on OpenLCA_Impact_Assessment_Tool? +

Register the TianGong-LCA-MCP Server MCP server in PolicyLayer and add a rule for OpenLCA_Impact_Assessment_Tool: 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 TianGong-LCA-MCP Server. Nothing to install.

What risk level is OpenLCA_Impact_Assessment_Tool? +

OpenLCA_Impact_Assessment_Tool is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit OpenLCA_Impact_Assessment_Tool? +

Yes. Add a rate_limit block to the OpenLCA_Impact_Assessment_Tool 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.

How do I block OpenLCA_Impact_Assessment_Tool completely? +

Set action: deny in the PolicyLayer policy for OpenLCA_Impact_Assessment_Tool. 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.

What MCP server provides OpenLCA_Impact_Assessment_Tool? +

OpenLCA_Impact_Assessment_Tool is provided by the TianGong-LCA-MCP Server MCP server (linancn/tiangong-lca-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every TianGong-LCA-MCP Server tool call.

Start from TianGong-LCA-MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
