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

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

## Why add_tag_alias is rated Medium

This tool creates or modifies synonym mappings within the knowledge graph's tag system. While it affects metadata organization, it is reversible (aliases can be removed or updated) and has a limited blast radius if misused—an agent could create confusing or redundant tag aliases, but this does not irreversibly delete data, execute arbitrary code, or cause financial impact.

From the tool's own definition: "Tool description states 'Add a tag alias (synonym mapping)' which creates a new mapping/association in the knowledge graph. The verb 'Add' indicates data creation rather than retrieval or deletion."

## Use case

AI agents use add_tag_alias to create or update resources in Enhanced Knowledge Graph Memory Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Enhanced Knowledge Graph Memory Server environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Enhanced Knowledge Graph Memory Server:

```json
