AI agents call x711_agent_act to retrieve information from x711 — Universal Agent Gas Station without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though x711_agent_act only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Give any agent hands. Pass a URL + natural-language instruction → x711 executes it: fills and submits forms, follows links, extracts structured data (tables, lists, prices). No Playwright. No Puppeteer. No browser setup. Together with x711_agent_see this is a full browser in two tool calls — agents that can see + act can navigate the entire internet autonomously. Instruction examples: 'fill the email field with user@example.com and submit', 'extract all product prices', 'follow the login link and return the page'. Returns: { action_performed, result, page_status }. JS SPA warning included if detected. Cost: $0.05. Requires API key.. It is categorised as a Read tool in the x711 — Universal Agent Gas Station MCP Server, which means it retrieves data without modifying state.
Register the x711 — Universal Agent Gas Station MCP server in PolicyLayer and add a rule for x711_agent_act: 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 x711 — Universal Agent Gas Station. Nothing to install.
x711_agent_act is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the x711_agent_act 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 x711_agent_act. 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.
x711_agent_act is provided by the x711 — Universal Agent Gas Station MCP server (https://x711.io/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
