# rank_markets

Use when a user wants "the top N markets for X" — one ranked list across the 300+ market set rather than N separate get_market_intel calls. Example: "What are the 10 fastest-growing US markets with at least 100MW of existing capacity?" — rank_markets criteria=fastest_growing region=us limit=10 min_capacity_mw=100. Params: criteria one of "cheapest_power" | "most_capacity" | "most_operators" | "fastest_growing" | "best_overall" (default best_overall) | "ai_ready"; region one of "global" | "us" | "canada" | "eu" | "apac" | "americas" (default us); limit 1-50 (default 10); min_capacity_mw filter floor (e.g. 100). ★ criteria="ai_ready" ranks by DCPI BUILDABILITY (excess-power + time-to-power + BUILD/CAUTION/AVOID verdict) — where NEW AI-campus load can actually LAND — NOT by installed build-out (the other five criteria). Use ai_ready for AI/GPU/hyperscale campus siting: the most-built-out markets are frequently AVOID for new load, so a build-out ranking mis-answers "where do I put a 200MW AI campus". Returns: {criteria, region, result_count, results:[{rank, metro_slug, market, city, state, country, score, value, total_mw, facility_count, operator_count, url}], data_source, methodology}. To drill into a ranked market, feed results[].metro_slug into get_market_dcpi_rank. Do NOT use for a deep read on ONE market (use get_market_intel) or for scoring a specific lat/lon (use analyze_site).

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

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

## Why rank_markets is rated High

rank_markets triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

## Use case

AI agents invoke rank_markets to trigger actions in Mcp Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "rank_markets": {
      "limits": [
        {
          "counter": "rank_markets_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
