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 ...
AI agents call list_solana_validators to retrieve information from VaultPilot MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
limit | integer | — | Maximum number of validators to return after filtering + sorting. Defaults to 25; max 100. |
sortBy | string | — | Sort order. `score` (default) = stakewiz composite wiz_score descending (best quality first). `apy` = total APY descending (inflation + MEV). `stake` = activate |
filters | object | — | Optional filters applied before sorting. Defaults: excludeDelinquent=true, excludeSuperminority=false, no commission/stake/MEV restriction. |
Parameters from the server's own tool schema.
Even though list_solana_validators only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

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. It is categorised as a Read tool in the VaultPilot MCP MCP Server, which means it retrieves data without modifying state.
list_solana_validators accepts 3 parameters: limit, sortBy, filters. The full parameter table on this page comes from the server's own tool schema.
Register the VaultPilot MCP server in PolicyLayer and add a rule for list_solana_validators: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches VaultPilot MCP. Nothing to install.
list_solana_validators is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_solana_validators rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_solana_validators. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_solana_validators is provided by the VaultPilot MCP server (vaultpilot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
