AI agents call get_balances to retrieve information from Refinore without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves account balance information without modifying, executing, or destroying any data. It is a simple query operation that reads blockchain state. While the broader server context involves financial operations (Solana tokens, swaps, mining), this specific tool only performs read-only lookups.
From the tool's definition Tool name 'get_balances' and description 'Get wallet token balances' explicitly indicate data retrieval with no side effects. It queries balances for SOL, ORE, USDC, stORE, and SKR tokens.
Attacks that exploit this kind of access
Get wallet token balances including SOL, ORE, USDC, stORE, and SKR for a given Solana wallet address. It is categorised as a Read tool in the Refinore MCP Server, which means it retrieves data without modifying state.
Register the Refinore MCP server in PolicyLayer and add a rule for get_balances: 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 Refinore. Nothing to install.
get_balances is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_balances 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 get_balances. 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.
get_balances is provided by the Refinore MCP server (jusscubs/refinore-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
