# get_btc_multisig_utxos

Return the UTXO set for a registered multi-sig wallet. Same gap-limit walk as get_btc_multisig_balance; each UTXO carries the witnessScript + cosigner pubkeys needed to build a multi-sig PSBT input. Used internally by prepare_btc_multisig_send (initiator flow); also exposed directly for users who want to inspect the spendable set without preparing a tx. No device touch.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `gapLimit` | integer | no |  |
| `walletName` | string | yes | Name of a registered multi-sig wallet. The returned UTXO set is the input pool PR3's `prepare_btc_multisig_send` will draw from. |

Parameters from the server's own tool schema.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_btc_multisig_utxos",
    "arguments": {
      "walletName": "<walletName>"
    }
  }
}
```

## Why get_btc_multisig_utxos is rated Low

get_btc_multisig_utxos retrieves and queries existing blockchain data from a registered multi-sig wallet. The description emphasizes inspection and data retrieval—returning witness scripts and public keys—without creating transactions, spending funds, or altering any state. While the tool operates in a financial context (crypto wallets), it performs only read operations on wallet metadata and UTXO data.

From the tool's own definition: "Tool returns UTXO set and wallet data without modifying state; explicitly states 'No device touch' and is 'Used internally by prepare_btc_multisig_send' as a read-ahead operation."

## Use case

AI agents call get_btc_multisig_utxos 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_btc_multisig_utxos": {}
  }
}
