Check if an address can vote on a proposal
AI agents call check_vote_eligibility to retrieve information from Sperax Ecosystem Crypto & DeFI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only check of voting permissions for a governance address. It retrieves information about whether an address meets eligibility criteria for voting, similar to a query or lookup operation. There are no side effects, no data modification, no execution of external operations, and no financial transactions involved. The operation is purely informational.
From the tool's definition Tool name 'check_vote_eligibility' and description 'Check if an address can vote on a proposal' indicate a query operation that retrieves voting eligibility status without modifying any state or executing transactions.

PolicyLayer is an MCP gateway — it sits between your AI agents and Sperax Ecosystem Crypto & DeFI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for check_vote_eligibility:
{
"version": "1",
"default": "deny",
"tools": {
"check_vote_eligibility": {}
}
} check_vote_eligibility is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Sperax Ecosystem Crypto & DeFI MCP Server MCP server in PolicyLayer and add a rule for check_vote_eligibility: 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 Sperax Ecosystem Crypto & DeFI MCP Server. Nothing to install.

Yes. Add a rate_limit block to the check_vote_eligibility 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 check_vote_eligibility. 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.
check_vote_eligibility is provided by the Sperax Ecosystem Crypto & DeFI MCP Server MCP server (sperax/sperax-crypto-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Sperax Ecosystem Crypto & DeFI MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
