Wait for selector/text then return snapshot. Combines wait_for + browser_snapshot in one call.
AI agents invoke wait_and_snapshot to trigger actions in MCP Camoufox. 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.
This tool executes browser commands (wait, snapshot capture) whose effects depend on the selector/text arguments provided by the user. While snapshot capture alone might be Read, the combination with 'wait for' (a polling/blocking operation) makes it Execute — it performs an action-triggering operation.
From the tool's definition Tool performs 'wait for selector/text then return snapshot' — it executes browser automation logic (waiting for DOM changes, capturing state).
Documented attack patterns abuse exactly the kind of access wait_and_snapshot gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Camoufox, and nothing reaches the server without passing your rules. This is the rule we recommend for wait_and_snapshot:
{
"version": "1",
"default": "deny",
"tools": {
"wait_and_snapshot": {
"limits": [
{
"counter": "wait_and_snapshot_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}wait_and_snapshot 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.
Free to start. No card required.
Wait for selector/text then return snapshot. Combines wait_for + browser_snapshot in one call. It is categorised as a Execute tool in the MCP Camoufox MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the MCP Camoufox MCP server in PolicyLayer and add a rule for wait_and_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 MCP Camoufox. Nothing to install.
wait_and_snapshot 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 wait_and_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.
Set action: deny in the PolicyLayer policy for wait_and_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.
wait_and_snapshot is provided by the MCP Camoufox MCP server (robithyusuf/mcp-camoufox). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Camoufox, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
