AI agents call get_btc_block_stats 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
hashOrHeight | object | Yes | Either a 64-hex block hash OR a block height. The RPC method `getblockstats` accepts both forms — pick whichever the agent already has on hand. |
Parameters from the server's own tool schema.
Even though get_btc_block_stats 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.

READ-ONLY — bitcoind getblockstats(hashOrHeight) output: fee distribution (min / max / avg / 10/25/50/75/90 percentile feerates in sat/vB), tx count, block size, total fees. RPC-only — Esplora exposes block size + tx count but NOT fee percentiles. Used to spot fee-market anomalies and to baseline mempool_anomaly. Requires BITCOIN_RPC_URL configured. Issue #248 / #233 v2. It is categorised as a Read tool in the VaultPilot MCP MCP Server, which means it retrieves data without modifying state.
get_btc_block_stats accepts 1 parameter: hashOrHeight. Required: hashOrHeight. The full parameter table on this page comes from the server's own tool schema.
Register the VaultPilot MCP server in PolicyLayer and add a rule for get_btc_block_stats: 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_block_stats 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_block_stats 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_block_stats. 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_block_stats 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.
