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

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

## Why listAllApis is rated Low

This tool queries and returns information about available APIs without modifying, executing, or deleting anything. It serves a discovery purpose to help users identify which API to call next. The blast radius of misuse is minimal—an AI agent listing APIs cannot cause damage, though it gains information about what APIs exist.

From the tool's own definition: "Tool name 'listAllApis' and description 'List available API IDs grouped by category' indicate a retrieval operation with no side effects. The verb 'list' is explicitly mentioned as a Read category example in the classification rules."

## Use case

AI agents call listAllApis to retrieve information from Dynamic API Server (MCP) 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 Dynamic API Server (MCP):

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

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
