# content_ranking

Return the TOP-ranked content entities in a category, by a chosen criterion — the direct answer to superlative / decision queries: 'best video games', 'top RPGs', 'cheapest games', 'best value RPGs', 'best FPS playable right now', 'most popular music artists'. Criteria: critic_score, popularity, price, value (critic score per unit price). direction flips it (asc = cheapest/lowest first). available_only restricts to entities currently buyable. Sliceable by genre and release-year window; every result carries its score, price and source. When to use: an agent must produce a ranked shortlist to support a recommendation, a purchase or a 'what is the best X' decision.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `async` | boolean | no | If true, returns a job_id immediately (<200ms) instead of waiting for the result. Poll the result with job_result(job_id). Use for slow tools to avoid client ti |

| `limit` | integer | no | Number of ranked results (default 20) |
| `domain` | string | yes | Content domain to rank within |
| `year_to` | integer | no | Optional latest release year |
| `criterion` | string | no | critic_score (0-100, default) · popularity · price · value (critic score per unit price) |
| `direction` | string | no | desc = best/highest first (default); asc = cheapest/lowest/least first. Defaults to asc for price. |
| `year_from` | integer | no | Optional earliest release year |
| `available_only` | boolean | no | If true, restrict to entities currently available to buy/play (default false) |

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "content_ranking",
    "arguments": {
      "domain": "<domain>"
    }
  }
}
```

## Why content_ranking is rated Low

This is a data retrieval and ranking tool with no capability to modify, delete, or execute external operations. It answers superlative queries by querying a content database and returning sorted results. The blast radius of misuse is minimal—an agent could only retrieve ranked lists, not cause damage or unintended system changes.

From the tool's own definition: "Tool returns ranked content entities by criteria (critic_score, popularity, price, value) with filtering options. No mutations, deletions, or side effects occur—it only retrieves and ranks existing data."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call content_ranking to retrieve information from Mcp Knowledge 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 Mcp Knowledge:

```json
{
  "version": "1",

  "tools": {
    "content_ranking": {}
  }
}
