AI agents use create_html_page to create or update resources in Street View MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Street View MCP environment.
The tool creates new content (HTML page) which is a reversible write operation. Without a description, confidence is reduced. The tool appears designed to generate virtual tour content within the Street View MCP context. Medium severity: misuse could generate misleading or malicious HTML pages, but the impact is limited to the user's local filesystem and the action is reversible.
From the tool's definition Tool named 'create_html_page' with empty description. Based on naming alone, this creates (generates/writes) an HTML page file.
Documented attack patterns abuse exactly the kind of access create_html_page gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Street View MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for create_html_page:
{
"version": "1",
"default": "deny",
"tools": {
"create_html_page": {
"limits": [
{
"counter": "create_html_page_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_html_page stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

create_html_page. It is categorised as a Write tool in the Street View MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Street View MCP server in PolicyLayer and add a rule for create_html_page: 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 Street View MCP. Nothing to install.
create_html_page is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_html_page 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 create_html_page. 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.
create_html_page is provided by the Street View MCP server (vlad-ds/street-view-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Street View MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
