WHAT IT DOES

What app_invoke_element does on Eda Agent

AI agents invoke app_invoke_element to trigger actions in Eda Agent. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why app_invoke_element is rated High

Tool invokes element operations in Altium Designer with unclear scope; potential to trigger unintended design modifications or deletions.

From the tool's definition uninformative description; invoke_element suggests running operations on design elements

RECOMMENDED RULE

The rule that runs app_invoke_element safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Eda Agent, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For app_invoke_element, this is the rule to start with:

app_invoke_element Rate-limited

app_invoke_element 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Eda Agent, apply this rule, and every app_invoke_element call is checked against it from then on.
