Merge two categories by moving all posts from source to target category
AI agents use merge-categories to create or update resources in AutoWP MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AutoWP MCP Server environment.
This tool modifies data (post-category relationships) but does not irreversibly delete or destroy content, nor does it execute arbitrary code or move money. It is a Write operation because it alters WordPress post metadata.
From the tool's definition The tool description explicitly states it "moving all posts from source to target category," which modifies post associations reversibly.
Documented attack patterns abuse exactly the kind of access merge-categories gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AutoWP MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for merge-categories:
{
"version": "1",
"default": "deny",
"tools": {
"merge-categories": {
"limits": [
{
"counter": "merge-categories_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}merge-categories 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.
Free to start. No card required.
Merge two categories by moving all posts from source to target category. It is categorised as a Write tool in the AutoWP MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the AutoWP MCP Server MCP server in PolicyLayer and add a rule for merge-categories: 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 AutoWP MCP Server. Nothing to install.
merge-categories 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 merge-categories 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 merge-categories. 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.
merge-categories is provided by the AutoWP MCP Server MCP server (njengah/autowpmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AutoWP MCP Server, 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.
