- Server: Faker MCP Server (`kentrino/faker-mcp-server`) — https://policylayer.com/tools/kentrino-faker-mcp-server.md
- Homepage: https://github.com/kentrino/faker-mcp-server
- Risk category: Read (Low risk)
- Registry record: grade C, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why system-semver is rated Low

This tool is part of a Faker.js-based server that generates fake data. It returns a randomly generated semantic version string. This is a pure read/generation operation with no side effects, no data modification, and no external system interaction. Severity is low as misuse would only result in fake version strings being generated.

From the tool's own definition: "Returns a semantic version — purely generates/retrieves fake data with no side effects"

Risk signals: Admin/system-level operation

## Use case

AI agents call system-semver to retrieve information from Faker MCP 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 Faker MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "system-semver": {}
  }
}
```
