Generate a new agent wallet with EVM (Base/Arbitrum/Ethereum) and Solana addresses
AI agents use create_wallet 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.
This tool creates a new cryptocurrency wallet, which is a Write action (creating new data/resources). However, it has high severity because generating a wallet in a financial context creates infrastructure that can hold and transact real cryptocurrency.

Documented attack patterns abuse exactly the kind of access create_wallet 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 create_wallet:
{
"version": "1",
"default": "deny",
"tools": {
"create_wallet": {
"limits": [
{
"counter": "create_wallet_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_wallet 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 agent wallet with EVM (Base/Arbitrum/Ethereum) and Solana addresses. 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 create_wallet: 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.
create_wallet 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 create_wallet 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 create_wallet. 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.
create_wallet 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.
