## Why get_bridges is rated Low

This tool queries bridge information from cryptocurrency APIs (DefiLlama Pro, CoinGecko Pro, Arkham Intelligence) without modifying, deleting, or executing operations. It has no financial impact, cannot execute code, and produces no side effects beyond retrieving data. The blast radius of misuse is minimal—an agent could retrieve excessive bridge data but cannot manipulate it or cause irreversible harm.

From the tool's own definition: "Tool name 'get_bridges' with description 'GET /bridges' indicates a simple HTTP GET endpoint that retrieves bridge data. The verb 'get' and HTTP method confirm read-only data retrieval."

## Use case

AI agents call get_bridges to retrieve information from REI Crypto MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches REI Crypto MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_bridges": {}
  }
}
```
