# datasets_techstack_search

Search the website tech-stack dataset. Searches the website tech-stack index (dataset id enum value techstack) — one record per site listing the web technologies it is built with (frameworks, CMS, e-commerce, analytics, CDNs, servers, and more), BuiltWith / Wappalyzer-style. The reverse-index filters are the point: repeat technology to require several at once (AND), any_of to match at least one (OR), and not to exclude — e.g. sites on Shopify and Klaviyo but not Recharge. Sort enum: relevance, rank_asc, tech_count_desc, domain_asc, crawled_desc. render_tier enum: http, browser.

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

```json
{
  "jsonrpc": "2.0",

    "name": "datasets_techstack_search",

## Why datasets_techstack_search is rated Low

Even though datasets_techstack_search only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Risk signals: High parameter count (20 properties)

## Use case

AI agents call datasets_techstack_search to retrieve information from Crawlora 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 Crawlora:

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