# get_ltc_block_tip

READ-ONLY — current Litecoin mainnet chain tip. Mirror of get_btc_block_tip for Litecoin: height, 64-hex hash, timestamp, ageSeconds, optional MTP + difficulty. Backed by the configured indexer (litecoinspace.org default; LITECOIN_INDEXER_URL env var or litecoinIndexerUrl user-config override for self-hosted Esplora). LTC blocks target 2.5 minutes — a 10-min gap is well within Poisson normal but worth surfacing. Issue #233 v1 (this tool was missing from the MCP surface despite the underlying indexer method existing in code).

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "get_ltc_block_tip",
    "arguments": {}

## Why get_ltc_block_tip is rated Low

This tool only retrieves blockchain state information without modification, side effects, or execution capabilities. It queries a public blockchain indexer for immutable chain tip data. The read-only designation and query-only nature (no write, execute, or financial operations) place it firmly in the Read category with low severity.

From the tool's own definition: "Tool name includes 'get_' prefix and description explicitly states 'READ-ONLY — current Litecoin mainnet chain tip'. Returns chain metadata: height, hash, timestamp, ageSeconds, MTP, difficulty."

## Use case

AI agents call get_ltc_block_tip to retrieve information from VaultPilot MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches VaultPilot MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_ltc_block_tip": {}
  }
}
