Address summary (UTXO + tx counts).
AI agents call get_address to retrieve information from Mcp Mempool Space without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves data about a Bitcoin address including UTXO information and transaction counts. It performs a read-only operation on public blockchain data with no side effects, state changes, or external actions triggered. The blast radius is minimal as misuse would only result in querying public information that is already visible on the blockchain.
From the tool's definition Tool name 'get_address' and description 'Address summary (UTXO + tx counts)' indicate retrieval of publicly available blockchain data without modification or execution of code/commands.
Attacks that exploit this kind of access
Address summary (UTXO + tx counts). It is categorised as a Read tool in the Mcp Mempool Space MCP Server, which means it retrieves data without modifying state.
Register the Mcp Mempool Space MCP server in PolicyLayer and add a rule for get_address: 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 Mcp Mempool Space. Nothing to install.
get_address 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_address 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_address. 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_address is provided by the Mcp Mempool Space MCP server (pipeworx-io/mcp-mempool-space). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
