  "jsonrpc": "2.0",

## Why get_latest_block is rated Low

This tool merely fetches and returns information about the latest block on the Ethereum Virtual Machine. It performs no mutations, executions, deletions, or financial transactions. The blast radius of misuse is minimal — an agent cannot cause harm by repeatedly querying block data. Classified as Read per the definition: 'retrieves or queries data; no side effects'.

From the tool's own definition: "Tool name is 'get_latest_block' and description states 'Get the latest block from the EVM' — a pure query operation that retrieves read-only blockchain state data with no side effects."

## Use case

AI agents call get_latest_block to retrieve information from SEI MCP Server V2 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 SEI MCP Server V2:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
