AI agents call WALLET_ADDRESS to retrieve information from Solana Agent Kit MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns wallet address data without modifying, executing operations, or committing financial transactions. It is a straightforward read operation with minimal blast radius if misused by an agent—returning a wallet address poses no inherent security or financial risk on its own.
From the tool's definition Tool name is 'WALLET_ADDRESS' with description 'Get the wallet address'. This retrieves wallet address information with no side effects.
Documented attack patterns abuse exactly the kind of access WALLET_ADDRESS gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Solana Agent Kit MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for WALLET_ADDRESS:
{
"version": "1",
"default": "deny",
"tools": {
"WALLET_ADDRESS": {}
}
}WALLET_ADDRESS is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Yes. Add a rate_limit block to the WALLET_ADDRESS 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 WALLET_ADDRESS. 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.
