## Facts

- Tool: `import_vectors`
- Server: Mcpg (`pypi:mcpg`) — https://policylayer.com/tools/io-github-devopam-mcpg.md
- Install: `npx -y pypi:mcpg`
- Homepage: https://github.com/devopam/MCPg
- 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": "import_vectors",
    "arguments": {}
  }
}
```

## Why import_vectors is rated Medium

The tool loads external vector data into a PostgreSQL database, which is a write operation that modifies database state. While reversible (can be deleted), the scope could be large (bulk import) and impact production systems. Classified as Write rather than Destructive since imports are typically reversible.

From the tool's own definition: "Tool name 'import_vectors' on a PostgreSQL MCP server indicates data insertion/loading. The name directly suggests bulk data import operations."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "import_vectors": {
      "limits": [
        {
          "counter": "import_vectors_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`
