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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "validate_address",
    "arguments": {}

## Why validate_address is rated Low

Address validation is a read-only operation that performs format verification and returns a boolean or validation status. It has no side effects, does not interact with the blockchain, does not move funds, and does not execute code. This is a safe, passive check operation.

From the tool's own definition: "Tool name 'validate_address' with description 'Validate a Bitcoin address' indicates a query operation that checks address format/validity without modifying state or executing transactions."

## Use case

AI agents call validate_address to retrieve information from Bitcoin MCP Server 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 Bitcoin MCP Server:

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