## Facts

- Tool: `fetch`
- Server: Agenttool (`https://api.agenttool.dev/v1/mcp`) — https://policylayer.com/tools/dev-agenttool-agenttool.md
- Homepage: https://github.com/cambridgetcg/agenttool
- Risk category: Read (Low risk)
- Registry record: grade F, 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": "fetch",
    "arguments": {}
  }
}
```

## Why fetch is rated Low

Even though fetch only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

## Use case

AI agents call fetch to retrieve information from Agenttool 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 Agenttool:

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

## 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`
