## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "discover_services",
    "arguments": {}
  }
}
```

## Why discover_services is rated Low

Despite being on a financial infrastructure server, this tool only searches/queries available services and products. It retrieves information without creating charges, modifying accounts, executing transactions, or committing financial obligations. The action is passive discovery, analogous to browsing a marketplace catalog.

From the tool's own definition: "Tool description states 'Search available services and products in the MIDAS marketplace' — a read-only query operation with no side effects."

## Use case

AI agents call discover_services to retrieve information from MIDAS Protocol 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 MIDAS Protocol:

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