## Facts

- Tool: `clear_graph`
- Server: Obsidian Elite RAG MCP Server (`aegntic/aegntic-mcp`) — https://policylayer.com/tools/aegntic-aegntic-mcp.md
- Homepage: https://github.com/aegntic/aegntic-MCP
- Risk category: Destructive (Critical risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Hidden

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

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

## Why clear_graph is rated Critical

This tool performs an irreversible operation that deletes all data from the graph memory. While it rebuilds indices, the underlying knowledge graph data is permanently removed and cannot be recovered without external backups. This is a destructive action with significant blast radius in a knowledge management system—an AI agent invoking this without intent could erase an entire user's semantic knowledge base.

From the tool's own definition: "Tool name 'clear_graph' combined with description 'Clear all data from the graph memory and rebuild indices' indicates irreversible deletion of graph data structures that support the RAG system's knowledge base."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call clear_graph to permanently remove resources in Obsidian Elite RAG MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Obsidian Elite RAG MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "clear_graph"
  ]
}
```
