## Install

### Claude Code

```bash
claude mcp add --transport http quizlar-mcp-server https://mcp.quizlar.app/mcp/ --header "Authorization: <your Authorization>"
```

### Claude (claude.ai, Desktop)

Not applicable: this server needs a custom header (Authorization) that custom connectors in claude.ai cannot send. Use Claude Code or a config file.

### Cursor

```json
{
  "mcpServers": {
    "quizlar-mcp-server": {
      "url": "https://mcp.quizlar.app/mcp/",
      "headers": {
        "Authorization": "<your Authorization>"
      }
    }
  }
}
```

Save as ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project).

### ChatGPT

Not applicable: this server needs a custom header (Authorization); ChatGPT connectors support no authentication or OAuth only.

### Hermes Agent

```yaml
mcp_servers:
  quizlar-mcp-server:
    url: "https://mcp.quizlar.app/mcp/"
    headers:
      Authorization: "<your Authorization>"
```

Add to ~/.hermes/config.yaml, then run /reload-mcp.

Ranking rule: Within a category, entries sort by (1) latest verification: verified working, then reachable but sign-in required, then failing; (2) share of daily checks that passed; (3) number of sourced facts attached to the entry; (4) median response time of passing checks; (5) name. Nothing else counts. Rankings are never for sale: sponsors and paid plans cannot change an entry's position.
