WHAT IT DOES

What generate_mnemonic does on Agenti

AI agents call generate_mnemonic as a supporting operation in Agenti workflows.

RISK

Why generate_mnemonic is rated Low

This tool generates cryptographic key material (a BIP39 mnemonic seed phrase) and derives wallet addresses. It does not directly move money, delete data, execute code, or write to an external system — it produces local cryptographic output. However, the generated mnemonic controls full access to cryptocurrency wallets, so misuse (e.g., exfiltration of the mnemonic) has high financial impact.

RECOMMENDED RULE

The rule that runs generate_mnemonic safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Agenti, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For generate_mnemonic, this is the rule to start with:

generate_mnemonic Rate-limited

generate_mnemonic gets a rate cap, and everything else on the server is denied unless you say otherwise.

FAQ

Questions about generate_mnemonic

What does the generate_mnemonic tool do? +

Generate a new BIP39 mnemonic phrase and derive the first EVM and Solana wallet addresses from it. It is categorised as a Other tool in the Agenti MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on generate_mnemonic? +

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.

What risk level is generate_mnemonic? +

generate_mnemonic is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit generate_mnemonic? +

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.

How do I block generate_mnemonic completely? +

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.

What MCP server provides generate_mnemonic? +

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.
