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

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

## Why gitlab_search_users is rated Low

This tool retrieves user information from GitLab but does not create, modify, delete, or execute any operations. It performs a simple search query analogous to a directory lookup. The blast radius is minimal—an AI agent could gather information about GitLab users, but this information is either public or already authorized for the token in use. No side effects or irreversible actions are possible.

From the tool's own definition: "The tool description explicitly states it 'Search[es] GitLab users by email or username,' which is a data retrieval operation with no modification or deletion."

Risk signals: Admin/system-level operation

## Use case

AI agents call gitlab_search_users to retrieve information from Sage 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 Sage MCP:

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