# collections_list

List all knowledge collections in the workspace. Collections are named groups of files used for RAG search. Auto-created collections (per-agent, per-prompt) are hidden by default.

## Facts

- Tool: `collections_list`
- Server: Dialogbrain (`https://api.dialogbrain.com/mcp`) — https://policylayer.com/tools/io-github-saloprj-dialogbrain.md
- Homepage: https://github.com/saloprj/dialogbrain-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server auth posture: open
- Server rate-limited: no
- Parameters: 1
- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `include_inactive` | boolean | no | Include inactive collections. OMIT to list only active collections (the default). |

Parameters from the server's own tool schema.

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

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

## Why collections_list is rated Low

This tool queries and returns metadata about existing knowledge collections without creating, modifying, deleting, or executing anything. It has no side effects and poses minimal risk even if misused by an AI agent, as it only exposes organizational information about RAG collections.

From the tool's own definition: "Tool name 'collections_list' and description explicitly states it 'List[s] all knowledge collections' — a retrieval operation with no modification or execution. The term 'list' is a canonical Read operation."

## Use case

AI agents call collections_list to retrieve information from Dialogbrain 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 Dialogbrain:

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