Navigate to a URL and optionally scrape content in one operation. Auto-creates session if needed.
AI agents invoke navigate_and_scrape to trigger actions in ZMCPTools. 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-based actions (navigation, scraping) that are triggered by user/agent input. While not destructive to local data, it can access arbitrary URLs and extract content, making it an Execute category tool. Severity is high because a compromised agent could scrape sensitive websites, intellectual property, or perform reconnaissance on targets.
From the tool's definition Tool performs 'Navigate to a URL and optionally scrape content' which involves executing browser navigation and web scraping operations.
Documented attack patterns abuse exactly the kind of access navigate_and_scrape gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ZMCPTools, and nothing reaches the server without passing your rules. This is the rule we recommend for navigate_and_scrape:
{
"version": "1",
"default": "deny",
"tools": {
"navigate_and_scrape": {
"limits": [
{
"counter": "navigate_and_scrape_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}navigate_and_scrape 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.
Navigate to a URL and optionally scrape content in one operation. Auto-creates session if needed. It is categorised as a Execute tool in the ZMCPTools MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the ZMCPTools MCP server in PolicyLayer and add a rule for navigate_and_scrape: 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 ZMCPTools. Nothing to install.
navigate_and_scrape 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_and_scrape 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_and_scrape. 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_and_scrape is provided by the ZMCPTools MCP server (zachhandley/zmcptools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
