MOST DANGEROUS TOOLS

High Risk

The most dangerous Zerion tools

Execute · High get_swap_offers This tool retrieves swap/bridge quotes AND provides 'ready-to-sign tx data', meaning it prepares executable transaction payloads that, if signed and broadcast, would perform token swaps involving financial value transfer

1 of Zerion's 20 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Zerion

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

Cap read operations

{
  "get_bitcoin_address_info": {
    "limits": [
      {
        "counter": "get_bitcoin_address_info_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

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

FAQ

Questions about Zerion

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

20 tools across 1 categories: Read. 19 are read-only. 1 can modify, create, or delete data.

How do I enforce a policy on Zerion? +

Register the Zerion 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.
