# upload_data

Upload or replace a data file (CSV, JSON, TSV, XML, TXT, max 10MB) inside an already-deployed Deloc app WITHOUT redeploying. Use this to refresh dashboard data from databases or APIs on a schedule. The file is served at the same URL as the rest of the app, so client code that does fetch(

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

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

## Why upload_data is rated Medium

This tool creates or modifies data files reversibly—uploading or replacing CSV, JSON, TSV, XML, or TXT files up to 10MB in size within an already-deployed app. While this can affect the app's behavior (since the file is served via fetch), it doesn't execute arbitrary code, delete data irreversibly, or trigger financial transactions.

From the tool's own definition: "Tool description states 'Upload or replace a data file' and mentions refreshing data, which are write operations that modify existing files without permanent deletion or code execution."

## Use case

AI agents use upload_data 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:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "upload_data": {
      "limits": [
        {
          "counter": "upload_data_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
