WHAT IT DOES

What browser_session_record does on Ruflo

AI agents invoke browser_session_record to trigger actions in Ruflo. 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 browser_session_record is rated High

This tool launches a real browser session capable of executing JavaScript, performing login flows with cookie reuse, and interacting with dynamic web applications. This constitutes external operation execution with significant blast radius — an AI agent could use it to authenticate to third-party services, exfiltrate data via SPA interactions, or perform actions on behalf of a user in live web environments.

From the tool's definition Open a named, traced browser session: allocate an RVF cognitive container, begin a ruvector trajectory, then open the URL via agent-browser... real browser automation — JS-heavy SPA scraping, login flows with cookie reuse, replay against DOM-drifted versions

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs browser_session_record safely

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

browser_session_record Rate-limited

browser_session_record 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 Ruflo, apply this rule, and every browser_session_record call is checked against it from then on.

FAQ

Questions about browser_session_record

What does the browser_session_record tool do? +

Open a named, traced browser session: allocate an RVF cognitive container, begin a ruvector trajectory, then open the URL via agent-browser. Returns the session id and rvf path. Use when native WebFetch is wrong because you need real browser automation — JS-heavy SPA scraping, login flows with cookie reuse, replay against DOM-drifted versions, AIDefence PII gating before content reaches Claude. For static HTML pages, native WebFetch is faster and free. It is categorised as a Execute tool in the Ruflo MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on browser_session_record? +

Register the Ruflo MCP server in PolicyLayer and add a rule for browser_session_record: 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 Ruflo. Nothing to install.

What risk level is browser_session_record? +

browser_session_record is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit browser_session_record? +

Yes. Add a rate_limit block to the browser_session_record 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.

How do I block browser_session_record completely? +

Set action: deny in the PolicyLayer policy for browser_session_record. 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.

What MCP server provides browser_session_record? +

browser_session_record is provided by the Ruflo MCP server (ruvnet/ruflo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
