Trigger a specific prop to display
Single-target operation
Part of the Propresenter MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke props_trigger to trigger processes or run actions in Propresenter. 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.
props_trigger can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept 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.

Trigger a specific prop to display. It is categorised as a Execute tool in the Propresenter MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Add a rule in your Intercept YAML policy under the tools section for props_trigger. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Propresenter MCP server.
props_trigger 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 props_trigger rule in your Intercept 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 Intercept policy for props_trigger. 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.
props_trigger is provided by the Propresenter MCP server (@alxpark/propresenter-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
