Generate a transaction intent for setting the contenthash on a .wei name.
AI agents use intentSetWNSContenthash to create or update resources in Agentek Eth — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Agentek Eth environment.
This tool generates transaction intents to modify data on-chain (specifically, setting contenthash records for .wei domain names). While it does not execute the transaction itself, it prepares write operations that would alter blockchain state reversibly. The 'intent' nature means the actual transaction would require separate signing/submission, but the tool itself facilitates data modification.
From the tool's definition Tool name includes 'Set' and description states 'Generate a transaction intent for setting the contenthash on a .wei name.' The intent generation for modifying blockchain state (setting contenthash on a domain name) constitutes a Write operation that creates…
Documented attack patterns abuse exactly the kind of access intentSetWNSContenthash gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Agentek Eth, and nothing reaches the server without passing your rules. This is the rule we recommend for intentSetWNSContenthash:
{
"version": "1",
"default": "deny",
"tools": {
"intentSetWNSContenthash": {
"limits": [
{
"counter": "intentsetwnscontenthash_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}intentSetWNSContenthash 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.

Generate a transaction intent for setting the contenthash on a .wei name. It is categorised as a Write tool in the Agentek Eth MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Agentek Eth MCP server in PolicyLayer and add a rule for intentSetWNSContenthash: 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 Agentek Eth. Nothing to install.
intentSetWNSContenthash 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 intentSetWNSContenthash 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 intentSetWNSContenthash. 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.
intentSetWNSContenthash is provided by the Agentek Eth MCP server (nanidao/agentek). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Agentek Eth, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
