## Facts

- Tool: `sip018_verify`
- Server: Aibtc (`aibtcdev/aibtc-mcp-server`) — https://policylayer.com/tools/io-github-aibtcdev-mcp-server.md
- Homepage: https://github.com/aibtcdev/aibtc-mcp-server
- Risk category: Read (Low risk)
- Registry record: grade F, identity verified

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "sip018_verify",
    "arguments": {}
  }
}
```

## Why sip018_verify is rated Low

This is a cryptographic verification operation that reads and validates a signature to recover the signer's public key or address. It does not create, modify, delete, or execute external code—it only performs computation on supplied inputs to verify authenticity.

From the tool's own definition: "Tool name 'sip018_verify' and description 'Verify a SIP-018 signature and recover the signer' indicate a verification/recovery operation with no state modification."

## Use case

AI agents call sip018_verify to retrieve information from Aibtc 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 Aibtc:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "sip018_verify": {}
  }
}
```
