WHAT IT DOES

What execute_proposal does on Sperax Ecosystem Crypto & DeFI MCP Server

AI agents invoke execute_proposal to trigger actions in Sperax Ecosystem Crypto & DeFI MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

THE RISK

High Risk

Why execute_proposal needs a policy

While the tool itself executes an already-queued proposal (suggesting some governance delay protection), it still triggers external smart contract operations whose effects are irreversible and context-dependent on what the proposal contains. This falls under Execute rather than Write because it invokes autonomous external operations (blockchain transactions) rather than just recording data.

From the tool's definition Tool name 'execute_proposal' combined with description 'Execute a queued proposal after timelock delay' indicates execution of a governance action.

Documented attack patterns abuse exactly the kind of access execute_proposal gives an agent:

POLICY

How to control execute_proposal

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 execute_proposal:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "execute_proposal": {
      "limits": [
        {
          "counter": "execute_proposal_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

execute_proposal stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Point your MCP client (Claude, Cursor, anything) at your gateway URL.
