# list_solana_validators

Read-only validator-ranking helper for prepare_native_stake_delegate. Pulls the stakewiz.com public feed (no API key required) and returns a filtered + sorted list of Solana validators with the columns most relevant to delegation: composite quality score (wizScore), commission, MEV (Jito) status + commission, total APY estimate (inflation + MEV), activated stake, delinquent flag, superminority penalty flag, skip rate, uptime, version, country, and a per-validator stakewiz.com profile URL the user can open in a browser to verify independently. Default filters: excludeDelinquent=true. Default sort: wizScore descending. Default limit: 25 (max 100). USE THIS BEFORE prepare_native_stake_delegate so the agent can surface a small ranked menu instead of forcing the user to leave for stakewiz / validators.app and paste back a vote pubkey. INVARIANT #14 NOTE: this is a HELPER — the MCP is NOT the source of truth. Before delegating, the user MUST (1) open the chosen validator's stakewizUrl in a browser to re-verify activated stake / commission / delinquent status against an authority outside the MCP enumeration, and (2) byte-equality-check the votePubkey in the prepare_native_stake_delegate response against the one confirmed in step 1. The response's notes[] field surfaces these instructions verbatim — pass them through to the user.

## Why list_solana_validators is rated Low

This tool retrieves and queries publicly available validator data from stakewiz.com without making any modifications, executing commands, or altering state. It is purely informational, providing filtered rankings to inform a user's decision for staking delegation. The output serves as input to other tools but does not itself execute transactions or operations.

From the tool's own definition: "Tool name is 'list_solana_validators' and description states it is 'Read-only validator-ranking helper' that 'Pulls the stakewiz.com public feed' and 'returns a filtered + sorted list'. No write, execute, or destructive operations are performed."

## Use case

AI agents call list_solana_validators 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": {
    "list_solana_validators": {}
  }
}
```
