## Facts

- Tool: `read_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: 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": "read_graph",
    "arguments": {}
  }
}
```

## Why read_graph is rated Low

This tool performs a query operation that retrieves knowledge graph data from the Obsidian vault without side effects. It is a straightforward data retrieval function that does not create, modify, delete, or execute any operations. The blast radius is minimal since reading data poses no risk to system state or data integrity.

From the tool's own definition: "Tool name 'read_graph' and description 'Read the entire knowledge graph' explicitly indicate retrieval of graph data with no modification, deletion, or execution capabilities."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call read_graph to retrieve information from Obsidian Elite RAG 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 Obsidian Elite RAG MCP Server:

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

## 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`
