WHAT IT DOES

What browser_snapshot does on Taw Computer

AI agents call browser_snapshot to retrieve information from Taw Computer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why browser_snapshot needs a policy

This tool performs purely observational operations—taking screenshots and identifying interactive elements for reference. While it operates within a full Ubuntu desktop environment with browser capabilities, it does not execute code, modify data, delete anything, move money, or trigger external operations.

From the tool's definition Tool description states it 'screenshot the page, return both the screenshot and element refs' with no mention of modifying data, executing commands, or causing side effects. The functionality is limited to visual capture and element identification.

POLICY

How to control browser_snapshot

PolicyLayer is an MCP gateway — it sits between your AI agents and Taw Computer, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_snapshot:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "browser_snapshot": {}
  }
}

browser_snapshot is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Taw Computer — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about browser_snapshot

What does the browser_snapshot tool do? +

Inject numbered overlays on every visible interactive element (Set-of-Mark prompting), screenshot the page, return both the screenshot and element refs. Use browser_click_ref / browser_type_ref to interact. It is categorised as a Read tool in the Taw Computer MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on browser_snapshot? +

Register the Taw Computer MCP server in PolicyLayer and add a rule for browser_snapshot: 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 Taw Computer. Nothing to install.

What risk level is browser_snapshot? +

browser_snapshot is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit browser_snapshot? +

Yes. Add a rate_limit block to the browser_snapshot 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_snapshot completely? +

Set action: deny in the PolicyLayer policy for browser_snapshot. 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_snapshot? +

browser_snapshot is provided by the Taw Computer MCP server (tawgroup/taw-computer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Taw Computer tool call.

Start from Taw Computer, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
