Get balance for a specific RGB asset
AI agents call rgb_get_asset_balance to retrieve information from RGB Lightning Network MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves asset balance information, which is fundamentally a read operation. However, severity is elevated to 'medium' rather than 'low' because the data returned concerns financial assets on a blockchain network (RGB assets), and exposure of balance information could enable reconnaissance for theft or targeted attacks, even though the tool itself performs no state changes.
From the tool's definition Tool name 'rgb_get_asset_balance' and description 'Get balance for a specific RGB asset' indicate a query operation that retrieves financial data without modifying it.
Attacks that exploit this kind of access

Register the RGB Lightning Network MCP Server MCP server in PolicyLayer and add a rule for rgb_get_asset_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 RGB Lightning Network MCP Server. Nothing to install.
rgb_get_asset_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 rgb_get_asset_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 rgb_get_asset_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.
