What deploy_proxy does on Sperax Ecosystem Crypto & DeFI MCP Server

AI agents invoke deploy_proxy 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.

High Risk

Why deploy_proxy needs a policy

This tool triggers external blockchain operations (contract deployment) whose effects depend on arguments (proxy type, implementation address, etc.) and create permanent on-chain state. While it is not directly Financial or Destructive in the sense of deleting data, it is Execute because it runs external operations with irreversible consequences.

From the tool's definition Tool deploys proxy contracts (UUPS or TransparentUpgradeableProxy) which executes code on-chain and creates irreversible protocol infrastructure.

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

How to control deploy_proxy

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 deploy_proxy:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "deploy_proxy": {
      "limits": [
        {
          "counter": "deploy_proxy_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

deploy_proxy 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.

  1. Create a free account and register Sperax Ecosystem Crypto & DeFI MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about deploy_proxy

What does the deploy_proxy tool do? +

Deploy a proxy contract (UUPS or TransparentUpgradeableProxy) pointing to an implementation. It is categorised as a Execute tool in the Sperax Ecosystem Crypto & DeFI MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on deploy_proxy? +

Register the Sperax Ecosystem Crypto & DeFI MCP Server MCP server in PolicyLayer and add a rule for deploy_proxy: 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.

What risk level is deploy_proxy? +

deploy_proxy is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit deploy_proxy? +

Yes. Add a rate_limit block to the deploy_proxy 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.

How do I block deploy_proxy completely? +

Set action: deny in the PolicyLayer policy for deploy_proxy. 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.

What MCP server provides deploy_proxy? +

deploy_proxy 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.
