Index document in Elasticsearch

Agent View of the PolicyLayer registry record for `index_document`. HTML page: https://policylayer.com/tools/io-github-portel-dev-ncp/index-document

## Facts

- Tool: `index_document`
- Server: Ncp (`@portel/ncp`) — https://policylayer.com/tools/io-github-portel-dev-ncp.md
- Install: `npx -y @portel/ncp`
- Homepage: https://github.com/portel-dev/ncp
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why index_document is rated Medium

Indexing a document in Elasticsearch creates or modifies searchable data in the index. This is a Write operation because it persists data reversibly (indexed documents can be updated or removed). It is not Read (no retrieval), Execute (no arbitrary command execution), Destructive (indexing does not irreversibly delete data), or Financial.

From the tool's own definition: "Tool name 'index_document' combined with description 'Index document in Elasticsearch' indicates the tool writes/stores document data into an Elasticsearch index."

## Use case

AI agents use index_document to create or update resources in Ncp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ncp environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "index_document": {
      "limits": [
        {
          "counter": "index_document_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
