Generate a new BIP39 mnemonic phrase and derive the first EVM and Solana wallet addresses from it
AI agents use generate_mnemonic to create or update resources in Agenti — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Agenti environment.
An AI agent can call generate_mnemonic faster than any human can review — one bad instruction and it creates or modifies resources in Agenti by the hundred, each call as confident as the last.
Documented attack patterns abuse exactly the kind of access generate_mnemonic gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Agenti, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_mnemonic:
{
"version": "1",
"default": "deny",
"tools": {
"generate_mnemonic": {
"limits": [
{
"counter": "generate_mnemonic_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}generate_mnemonic 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 new BIP39 mnemonic phrase and derive the first EVM and Solana wallet addresses from it. It is categorised as a Write tool in the Agenti MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Agenti MCP server in PolicyLayer and add a rule for generate_mnemonic: 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 Agenti. Nothing to install.
generate_mnemonic 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 generate_mnemonic 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 generate_mnemonic. 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.
generate_mnemonic is provided by the Agenti MCP server (nirholas/agenti). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
