MOST DANGEROUS TOOLS

High Risk

The most dangerous Relay MCP Server tools

Execute · Critical execute_api_call This tool permits an AI agent to execute arbitrary API calls to a blockchain bridge/swap protocol with user-controlled parameters.

1 of Relay MCP Server'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 Relay MCP Server

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

Cap read operations

{
  "check_chain_status": {
    "limits": [
      {
        "counter": "check_chain_status_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 Relay MCP Server — 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 Relay MCP Server

Is the Relay MCP Server MCP server safe to use without restrictions? +

The Relay MCP Server server is primarily read-only with 19 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 Relay MCP Server MCP server expose? +

20 tools across 3 categories: Execute, Read, Write. 19 are read-only. 1 can modify, create, or delete data.

How do I enforce a policy on Relay MCP Server? +

Register the Relay MCP Server 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 Relay MCP Server tool call.

Deterministic rules across all 20 Relay MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
