AI agents invoke navigate_ui to trigger processes or run actions in Sidearm. 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.
navigate_ui 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.

Look up how to perform an action in the Sidearm dashboard UI. Returns step-by-step instructions for dashboard operations such as uploading media, running searches, managing API keys, reviewing deals, buying credits, and more. Use this when the user asks how to do something in the dashboard or web app. Omit the query to get an overview of all available pages.. It is categorised as a Execute tool in the Sidearm MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Sidearm MCP server in PolicyLayer and add a rule for navigate_ui: 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 Sidearm. Nothing to install.
navigate_ui 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 navigate_ui 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 navigate_ui. 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.
navigate_ui is provided by the Sidearm MCP server (sidearmdrm/sidearm). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
