# get_document_snapshot

Get one point-in-time Huly document history snapshot and return markdown content. Resolve the document by teamspace plus document title or ID; resolve the snapshot by snapshotId, exact snapshot title, or exact createdOn timestamp. Prefer snapshotId from list_document_snapshots when titles or dates may collide. Restore is out of scope.

## Why get_document_snapshot is rated Low

This tool retrieves a historical snapshot of a document and returns its content as markdown. There are no side effects, data modifications, or irreversible operations. It is a pure read operation that queries document history. The blast radius of misuse is minimal—an attacker gains visibility into historical document versions but cannot alter, delete, or execute operations through this tool.

From the tool's own definition: "Tool description states 'Get one point-in-time Huly document history snapshot and return markdown content.' The verb 'Get' and the phrase 'return markdown content' indicate read-only retrieval."

## Use case

AI agents call get_document_snapshot 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",
