Block detail by hash or height.
AI agents call get_block 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 publicly available blockchain data. It has no side effects, cannot modify state, and poses minimal risk if misused by an AI agent. It fits the Read category (retrieves or queries data; no side effects).
From the tool's definition Tool name: get_block. Tool description: 'Block detail by hash or height.' This retrieves block data from a public Bitcoin blockchain explorer without modifying, executing, or deleting any data.
Attacks that exploit this kind of access
Block detail by hash or height. 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_block: 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_block 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_block 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_block. 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_block 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.
