Set a guardian for a user in the SLOW contract
AI agents use intentSetSlowGuardian 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 modifies guardian settings for a user in the SLOW contract, which is a state-changing operation on a smart contract. Setting a guardian likely controls who can authorize or block transactions/unlocks for that user.

Documented attack patterns abuse exactly the kind of access intentSetSlowGuardian 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 intentSetSlowGuardian:
{
"version": "1",
"default": "deny",
"tools": {
"intentSetSlowGuardian": {
"limits": [
{
"counter": "intentsetslowguardian_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}intentSetSlowGuardian 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.
Set a guardian for a user in the SLOW contract. 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 intentSetSlowGuardian: 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.
intentSetSlowGuardian 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 intentSetSlowGuardian 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 intentSetSlowGuardian. 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.
intentSetSlowGuardian 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.
Free to start. No card required.
