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

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

## Why list_mcp_server_capabilities is rated Low

This tool retrieves and reports metadata about MCP server capabilities. It performs only information gathering and introspection with no ability to modify, delete, or execute operations. The blast radius of misuse is minimal since it merely exposes what is already available on the server.

From the tool's own definition: "Tool name is 'list_mcp_server_capabilities' and description states it 'List capabilities exposed by an MCP server instance. Returns total plus the current tool, resource, and prompt surface' — this is a query/inspection operation with no side effects."

## Use case

AI agents call list_mcp_server_capabilities to retrieve information from Portkey Admin 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 Portkey Admin:

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