Convert raw HTML to Markdown. Useful for testing conversion rules or converting arbitrary HTML content.
AI agents use convert_html to create or update resources in WP Astro MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your WP Astro MCP environment.
This tool performs a data transformation (HTML → Markdown) that is reversible and does not execute arbitrary code, delete data, or trigger financial transactions. It falls under Write category as it generates/modifies content. Severity is low because the conversion is a controlled, predictable operation on static content with no side effects on external systems or irreversible changes.
From the tool's definition Tool converts HTML to Markdown format, which creates or transforms data. Description states it is 'useful for testing conversion rules or converting arbitrary HTML content,' indicating data modification/creation rather than retrieval or execution of external…
Documented attack patterns abuse exactly the kind of access convert_html gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and WP Astro MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for convert_html:
{
"version": "1",
"default": "deny",
"tools": {
"convert_html": {
"limits": [
{
"counter": "convert_html_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}convert_html 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.

Convert raw HTML to Markdown. Useful for testing conversion rules or converting arbitrary HTML content. It is categorised as a Write tool in the WP Astro MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the WP Astro MCP server in PolicyLayer and add a rule for convert_html: 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 WP Astro MCP. Nothing to install.
convert_html 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 convert_html 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 convert_html. 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.
convert_html is provided by the WP Astro MCP server (vapvarun/wp-astro-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from WP Astro MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
