A read tool on the n8n MCP Server MCP server.

Agent View of the PolicyLayer registry record for `list_tags`. HTML page: https://policylayer.com/tools/andhit-r-n8n-mcp/list-tags

## Facts

- Tool: `list_tags`
- Server: n8n MCP Server (`andhit-r/n8n-mcp`) — https://policylayer.com/tools/andhit-r-n8n-mcp.md
- Homepage: https://github.com/andhit-r/n8n-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, 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": "list_tags",
    "arguments": {}
  }
}
```

## Why list_tags is rated Low

The 'list_' prefix conventionally denotes read-only retrieval operations that enumerate data. Tags are metadata entities typically used for organization and filtering, not for state modification. Sibling tools show that tag creation, deletion, and variable/credential management exist separately, confirming this tool's limited scope.

From the tool's own definition: "Tool name 'list_tags' indicates data retrieval operation. Function prefix 'list_' is a Read pattern (list, get, fetch, search). No description provided, but naming convention strongly suggests querying/retrieving tags without modification."

## Use case

AI agents call list_tags to retrieve information from n8n 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 n8n MCP Server:

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

## 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`
