# setup_data_refresh

Generate a complete backend script that queries a data warehouse and auto-refreshes a Deloc dashboard. Creates a ready-to-deploy Python project (main.py, requirements.txt, Dockerfile) with scheduling instructions. Supported data sources: Snowflake, Postgres, MySQL, or any HTTP/REST API. For BigQuery, prefer connect_bigquery + create_dashboard_query instead — Deloc then runs the query daily itself, with nothing for the user to host or schedule. Use this tool for BigQuery only if the user explicitly wants to run their own pipeline. Use this AFTER deploying a dashboard that fetches a data file (e.g. fetch(

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

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

## Why setup_data_refresh is rated Medium

This tool generates and creates project files (main.py, requirements.txt, Dockerfile) for a backend data refresh pipeline. It writes/creates artifacts rather than executing them directly or deleting anything. The output is a ready-to-deploy project, but deployment itself is a separate step.

From the tool's own definition: "Generate a complete backend script... Creates a ready-to-deploy Python project (main.py, requirements.txt, Dockerfile) with scheduling instructions"

## Use case

AI agents use setup_data_refresh to create or update resources in Deloc, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Deloc environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Deloc:
