## Facts

- Tool: `list_knowledge_categories`
- Server: FlowDot MCP Server (`flowdot-llc/mcp-server`) — https://policylayer.com/tools/flowdot-llc-mcp-server.md
- Homepage: https://github.com/flowdot-llc/mcp-server
- 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_knowledge_categories",
    "arguments": {}
  }
}
```

## Why list_knowledge_categories is rated Low

This tool retrieves and lists metadata about knowledge base organization. It has no capacity to create, modify, delete, or execute operations. The blast radius of misuse is minimal — an agent could enumerate categories but cannot access, modify, or harm underlying data or external systems. This is a classic Read operation.

From the tool's own definition: "Tool name is 'list_knowledge_categories' and description states it 'List[s] all document categories' — a retrieval operation with no modification or side effects."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call list_knowledge_categories to retrieve information from FlowDot 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 FlowDot MCP Server:

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

## 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`
