Get the total Bitcoin balance (in satoshis) of an address by summing all its deltas. Use this when you only need the balance information without the full address details.
AI agents call address_balance_get to retrieve information from Satstream MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves blockchain data (address balance) with no side effects, no data modification, and no external operations triggered. It is purely informational and read-only in nature. The low severity reflects the minimal risk of misuse—an agent querying Bitcoin balances poses no threat to user assets or system integrity.
From the tool's definition Tool name 'address_balance_get' and description 'Get the total Bitcoin balance (in satoshis) of an address by summing all its deltas' indicates a query operation that retrieves and returns balance data without modifying any state.

Get the total Bitcoin balance (in satoshis) of an address by summing all its deltas. Use this when you only need the balance information without the full address details. It is categorised as a Read tool in the Satstream MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Satstream MCP Server MCP server in PolicyLayer and add a rule for address_balance_get: 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 Satstream MCP Server. Nothing to install.
address_balance_get 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 address_balance_get 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 address_balance_get. 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.
address_balance_get is provided by the Satstream MCP Server MCP server (satstream/ss-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
