# vuln_patch_priority_engine

As a CTO, quickly prioritize unpatched CVEs by combining exploitability scores (EPSS) with cloud asset criticality. Input a list of CVE IDs and your AWS service types (e.g., EC2, RDS) to receive a ranked patching order with risk scores and estimated cloud impact. Uses public NVD, OpenCVE, and AWS pricing data. Ideal for vulnerability management and cloud security posture improvement.

## Facts

- Tool: `vuln_patch_priority_engine`
- Server: Mcp Knowledge (`https://mcp.gapup.io`) — https://policylayer.com/tools/io-github-getgapup-mcp-knowledge.md
- Homepage: https://github.com/getgapup/gapup-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server auth posture: open
- Server rate-limited: no
- Parameters: 4 (1 required)
- Recommended policy verdict: Allowed

## 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 |
| `cveIds` | array | yes | List of CVE identifiers to analyze (e.g., ["CVE-2021-44228", "CVE-2023-3824"]) |
| `maxResults` | number | no | Maximum number of prioritized CVEs to return (default: 10) |
| `awsServices` | array | no | AWS service types affected by these CVEs (e.g., ["EC2", "RDS", "Lambda"]) |

Parameters from the server's own tool schema.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "vuln_patch_priority_engine",
    "arguments": {
      "cveIds": []
    }
  }
}
```

## Why vuln_patch_priority_engine is rated Low

This tool reads and aggregates public vulnerability data (NVD, OpenCVE, EPSS scores) and AWS pricing data to produce a ranked list/report. It does not modify, execute, or delete anything — it is a read/query/analysis tool. Severity is medium because it processes sensitive security posture information (CVE IDs, AWS service types) that could reveal exploitable weaknesses if misused.

From the tool's own definition: "prioritize unpatched CVEs by combining exploitability scores (EPSS) with cloud asset criticality... ranked patching order with risk scores and estimated cloud impact. Uses public NVD, OpenCVE, and AWS pricing data"

## Use case

AI agents call vuln_patch_priority_engine 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",
  "default": "deny",
  "tools": {
    "vuln_patch_priority_engine": {}
  }
}
```
