# get_validator_info

Get comprehensive detailed information about a specific validator including staking metrics, commission rates, withdrawal fees, reward estimates, and performance calculations. Shows total staked, share ratios, APY estimates, and example reward calculations for different stake amounts (100 0G, 1000 0G). Useful for evaluating validators before staking. Read-only operation, no authentication needed.

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

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

## Why get_validator_info is rated Low

This tool queries blockchain data about validators and returns information to help users make staking decisions. It performs no state changes, creates no transactions, and modifies no data. The low severity reflects minimal risk if misused—an agent could only retrieve validator information, which is public blockchain data. No financial transactions, destructive operations, or code execution occur.

From the tool's own definition: "Tool description explicitly states 'Read-only operation, no authentication needed' and retrieves 'comprehensive detailed information about a specific validator including staking metrics, commission rates, withdrawal fees, reward estimates, and performance…"

## Use case

AI agents call get_validator_info to retrieve information from 0g Chain 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 0g Chain:

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