# candidate_screening_ranking

AI-powered candidate screening and ranking for recruiters, hiring managers, ATS providers and recruitment AI agents. Ingests a job description and 1-50 candidate resumes, returning a ranked shortlist with score breakdowns across five weighted criteria: skills_match (tech stack and soft skills extracted from JD vs resume), experience_match (years vs seniority level inferred from JD), education_match (degree level + top-school detection), role_progression (Junior to Senior to Lead patterns), culture_fit_estimate (remote/hybrid, startup vs enterprise). Per candidate: overall_score 0-100, matched/missing skills, red_flags (job hopping, employment gaps, seniority mismatch), green_flags (long tenure, promotions), 3-5 interview questions, fit_summary. Diversity signals are first-name proxies ONLY with mandatory ethical WARNING. All processing is local -- no external API calls, instant response, privacy-preserving.

## 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 |
| `candidates` | array | yes | Array of candidate objects. Maximum 50. |
| `role_country` | string | no | Optional ISO 2-letter country code for regional context (informational). |
| `job_description` | string | yes | Full text or summary of the job description and role requirements. |
| `criteria_weights` | object | no | Optional weighting per criterion. Default: skills=0.4, experience=0.2, education=0.1, progression=0.15, culture=0.15. |

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": "candidate_screening_ranking",
    "arguments": {
      "candidates": [],
      "job_description": "<job_description>"
    }
  }
}
```

## Why candidate_screening_ranking is rated Low

The tool reads and analyzes input data (job descriptions and resumes) and returns ranked results with scoring breakdowns. It does not modify, store, or delete data — it is purely an analytical/retrieval operation. Severity is medium because it processes sensitive personal data (resumes, candidate profiles) and automated ranking decisions could have discriminatory or privacy implications if misused.

From the tool's own definition: "AI-powered candidate screening and ranking... Ingests a job description and 1-50 candidate resumes, returning a ranked shortlist with score breakdowns"

Risk signals: High parameter count (15 properties)

## Use case

AI agents call candidate_screening_ranking to retrieve information from Gapup Mcp 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)
