Check your current SolanaProx balance. Returns available USDC and SOL balance that can be used for AI requests.
AI agents call check_balance to retrieve information from Solanaprox without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves financial account information (USDC and SOL balances) but does not move funds, execute transactions, or modify any data. It is a pure information retrieval operation. While it accesses financial data, it poses minimal risk as it only displays the user's own balance without the capability to transfer funds or commit financial obligations.
From the tool's definition Tool name 'check_balance' and description 'Check your current SolanaProx balance. Returns available USDC and SOL balance' indicate a read-only query operation with no side effects.
Attacks that exploit this kind of access
Check your current SolanaProx balance. Returns available USDC and SOL balance that can be used for AI requests. It is categorised as a Read tool in the Solanaprox MCP Server, which means it retrieves data without modifying state.
Register the Solanaprox MCP server in PolicyLayer and add a rule for check_balance: 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 Solanaprox. Nothing to install.
check_balance 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 check_balance 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 check_balance. 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.
check_balance is provided by the Solanaprox MCP server (solanaprox/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
check_balance is one line of Solanaprox's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
