- Homepage: https://github.com/dugynoo/huly-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no

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

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

## Why list_activity is rated Low

This tool retrieves and queries historical activity/audit log data for objects in Huly. It performs a read-only operation with no ability to create, modify, delete, or execute operations. The low severity reflects minimal risk even if misused by an AI agent, as it only exposes read access to activity history.

From the tool's own definition: "Tool name is 'list_activity' and description states it 'List activity messages' and 'Returns activity sorted by date'. The verb 'list' and 'returns' indicate data retrieval with no modification or side effects."

## Use case

AI agents call list_activity to retrieve information from Huly 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 Huly:

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