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

```json
{
  "jsonrpc": "2.0",

## Why cbs-get-metadata is rated Low

This tool retrieves metadata (column descriptions) for a CBS table, which is a read-only operation. It queries and returns information without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an attacker could only gain knowledge of table structure, not access sensitive data, modify records, or trigger external operations. This is a classic Read category tool.

From the tool's own definition: "Tool name 'cbs-get-metadata' and description 'Fetch metadata (column descriptions) for a specific CBS table ID' indicate retrieval of descriptive information without modification or execution of code."

## Use case

AI agents call cbs-get-metadata to retrieve information from Meta Data 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 Meta Data Mcp:

```json
