WHAT IT DOES

What deploy_create2 does on Sperax Ecosystem Crypto & DeFI MCP Server

AI agents invoke deploy_create2 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

Why deploy_create2 needs a policy

This tool enables execution of arbitrary smart contract deployment via CREATE2, which is a code execution mechanism on the blockchain. While deployment itself is not destructive (contracts can be replaced or abandoned), it represents active execution of code with external effects that depend heavily on which contract bytecode is provided as arguments.

From the tool's definition Tool name 'deploy_create2' combined with description 'Deploy a contract using CREATE2 for deterministic addresses across chains' indicates execution of contract deployment operations on blockchain networks.

Documented attack patterns abuse exactly the kind of access deploy_create2 gives an agent:

POLICY

How to control deploy_create2

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_create2:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "deploy_create2": {
      "limits": [
        {
          "counter": "deploy_create2_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

deploy_create2 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.

FAQ

Questions about deploy_create2

What does the deploy_create2 tool do? +

Deploy a contract using CREATE2 for deterministic addresses across chains. 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_create2? +

Register the Sperax Ecosystem Crypto & DeFI MCP Server MCP server in PolicyLayer and add a rule for deploy_create2: 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_create2? +

deploy_create2 is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit deploy_create2? +

Yes. Add a rate_limit block to the deploy_create2 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_create2 completely? +

Set action: deny in the PolicyLayer policy for deploy_create2. 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_create2? +

deploy_create2 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.
