AI agents invoke execute_lca_tool to trigger processes or run actions in Carbonfootprint. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
execute_lca_tool can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Execute any EcoSemantic LCA tool by name. Use discover_available_lca_tools() first to find available tools and their required parameters. Session defaults (set via set_lca_session_defaults) are applied automatically. Parameters: tool_name: Name of the tool to execute (e.g., 'search_activities') params: Dictionary of parameters for the tool Example: execute_lca_tool(tool_name="search_activities", params={"q": "electricity", "database": "ecoinvent-3.9.1-cutoff"}). It is categorised as a Execute tool in the Carbonfootprint MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Carbonfootprint MCP server in PolicyLayer and add a rule for execute_lca_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 Carbonfootprint. Nothing to install.
execute_lca_tool is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the execute_lca_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.
Set action: deny in the PolicyLayer policy for execute_lca_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.
execute_lca_tool is provided by the Carbonfootprint MCP server (ecosemantic/carbonfootprint). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
