## Why delimit_session_history is rated Low

The tool appears designed to query or fetch session history records within the Delimit workspace platform. No description is provided, which lowers confidence slightly, but the name strongly suggests this is a read-only operation to access historical data rather than modify, execute operations, or delete records. Historical data retrieval has minimal blast radius if misused by an agent.

From the tool's own definition: "Tool name 'delimit_session_history' suggests retrieval of historical session data. The empty description limits certainty, but the naming convention (past tense 'history') and context of a workspace management tool indicate this is a data retrieval operation…"

## Use case

AI agents call delimit_session_history to retrieve information from Delimit 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 Delimit:

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