MOST DANGEROUS TOOLS
High Risk

The most dangerous Etherscan MCP tools

Execute · Medium proxy__eth_call The tool executes a call against the Ethereum blockchain (smart contract call). Execute · Medium proxy__eth_estimateGas eth_estimateGas triggers a simulation of a transaction execution on the blockchain node.

2 of Etherscan MCP's 56 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Etherscan MCP

PolicyLayer is an MCP gateway — it sits between your AI agents and Etherscan MCP, and nothing reaches the server without passing your rules. These are the rules we recommend:

Cap read operations
{
  "account__balance": {
    "limits": [
      {
        "counter": "account__balance_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

  1. Create a free account and register Etherscan MCP — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Etherscan MCP

Is the Etherscan MCP server safe to use without restrictions? +

The Etherscan MCP server is primarily read-only with 54 read tools. While it cannot modify data, an agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up costs. Rate limiting is still recommended.

How many tools does the Etherscan MCP server expose? +

56 tools across 1 categories: Read. 54 are read-only. 2 can modify, create, or delete data.

How do I enforce a policy on Etherscan MCP? +

Register the Etherscan MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Etherscan MCP tool call.

Deterministic rules across all 56 Etherscan MCP tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
