AI agents use draft_item to create or update resources in FishClaw MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FishClaw MCP environment.
This tool creates and populates draft product listings on the Xianyu marketplace. While it does not publish or finalize listings (that appears to be publish_item's role), it writes/creates structured product data including descriptions, images, categories, and prices into draft form. This is reversible (drafts can be discarded or edited) and has no financial commitment until publication.
From the tool's definition Tool description indicates it 'fills in product draft' (填写商品草稿) on Xianyu publishing page with images, description, category, and price, then auto-captures screenshot.
Documented attack patterns abuse exactly the kind of access draft_item gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and FishClaw MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for draft_item:
{
"version": "1",
"default": "deny",
"tools": {
"draft_item": {
"limits": [
{
"counter": "draft_item_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}draft_item 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.

Register the FishClaw MCP server in PolicyLayer and add a rule for draft_item: 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 FishClaw MCP. Nothing to install.
draft_item 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 draft_item 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 draft_item. 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.
draft_item is provided by the FishClaw MCP server (tnoobt/fishclaw_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from FishClaw MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
