- Homepage: https://github.com/kentrino/faker-mcp-server
- Risk category: Read (Low risk)
- Registry record: grade C, identity unverified
- Server rate-limited: no

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

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

## Why system-mimeType is rated Low

This tool generates and returns fake MIME type data using Faker.js. It is a read/generate operation with no side effects, no data modification, and no destructive capabilities. The blast radius of misuse is minimal as it only produces synthetic data.

From the tool's own definition: "Returns a mime-type"

Risk signals: Admin/system-level operation

## Use case

AI agents call system-mimeType 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-mimeType": {}
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- 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`
