Get current Bitcoin mempool statistics including size, transaction count, and fee estimates. Use this to understand the current state of unconfirmed transactions.
AI agents call mempool_info_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 retrieves mempool statistics (size, transaction count, fee estimates) from the Bitcoin blockchain. It is a pure data query with no side effects, no code execution, and no ability to modify blockchain state or move funds. It falls squarely into the Read category with low severity since misuse would only expose publicly available blockchain data.
From the tool's definition Tool name 'mempool_info_get' and description 'Get current Bitcoin mempool statistics' indicates a read-only query operation that retrieves data without modifying state. No transaction submission, no state changes, no execution of code.
Attacks that exploit this kind of access
Get current Bitcoin mempool statistics including size, transaction count, and fee estimates. Use this to understand the current state of unconfirmed transactions. 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 mempool_info_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.
mempool_info_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 mempool_info_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 mempool_info_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.
mempool_info_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.
