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

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

## Why list_cards is rated Low

The tool performs a read-only operation that retrieves a list of existing questions/cards from Metabase. There are no destructive, write, execute, or financial implications. The blast radius of misuse is minimal—an AI agent listing cards cannot cause harm beyond potentially accessing information visibility. This is a standard Read category tool.

From the tool's own definition: "Tool name 'list_cards' and description 'List all questions/cards in Metabase' indicate a retrieval/query operation with no side effects. This is a listing operation that retrieves existing data without modifying, executing, or deleting anything."

## Use case

AI agents call list_cards to retrieve information from Metabase Analytics Integration 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 Metabase Analytics Integration Server:

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