Get transaction deltas (inputs and outputs) for a specific Bitcoin address with pagination. Use this to analyze the transaction history of an address with filtering by block height.
AI agents call address_deltas_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 queries blockchain data to retrieve transaction details for a Bitcoin address. It is explicitly descriptive as a GET operation with filtering and pagination parameters, indicating read-only access to historical blockchain information. There are no side effects, state changes, or destructive/financial operations. The worst-case misuse is information disclosure, which carries low security risk.
From the tool's definition Tool performs 'Get transaction deltas (inputs and outputs)' and 'analyze the transaction history' — purely data retrieval with no modification, deletion, or execution of code/commands.
Attacks that exploit this kind of access
Get transaction deltas (inputs and outputs) for a specific Bitcoin address with pagination. Use this to analyze the transaction history of an address with filtering by block height. 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_deltas_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_deltas_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_deltas_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_deltas_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_deltas_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.
