AI agents call get_btc_mempool_summary to retrieve information from VaultPilot MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though get_btc_mempool_summary only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
READ-ONLY — bitcoind getmempoolinfo output: tx count in mempool, total bytes, memory usage, current minimum admission feerate, total fees of mempool txs. RPC-only — Esplora's mempool view is whatever that one node sees; ours gives us the real local view + the daemon's admission policy. Used by get_market_incident_status to flip the mempool_anomaly signal from available: false to live computation. Requires BITCOIN_RPC_URL configured. Issue #248 / #236 v2. It is categorised as a Read tool in the VaultPilot MCP MCP Server, which means it retrieves data without modifying state.
Register the VaultPilot MCP server in PolicyLayer and add a rule for get_btc_mempool_summary: 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 VaultPilot MCP. Nothing to install.
get_btc_mempool_summary 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_btc_mempool_summary 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_btc_mempool_summary. 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_btc_mempool_summary is provided by the VaultPilot MCP server (vaultpilot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
