- Transports: `streamable-http`
- Auth: `none`
- Version: `1.0.1`

## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the endpoint returned HTTP 503.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

### How do I install the uk.firstmention.api/automaton MCP server?

uk.firstmention.api/automaton is a hosted endpoint at https://api.firstmention.uk/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

### Claude

```bash
claude mcp add --transport http uk-firstmention-api-automaton 'https://api.firstmention.uk/mcp'
```

### Cursor

```json
{
  "mcpServers": {
    "uk-firstmention-api-automaton": {
      "url": "https://api.firstmention.uk/mcp"
    }
  }
}
```

### VS Code

```json
{
  "servers": {
    "uk-firstmention-api-automaton": {
      "type": "http",
      "url": "https://api.firstmention.uk/mcp"
    }
  }
}
```

### Codex

```toml
[mcp_servers.uk-firstmention-api-automaton]
url = "https://api.firstmention.uk/mcp"
```

### opencode

```json
{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "uk-firstmention-api-automaton": {
      "type": "remote",
      "url": "https://api.firstmention.uk/mcp",
      "enabled": true
    }
  }
}
```

### OpenClaw

```bash
openclaw mcp add uk-firstmention-api-automaton --url 'https://api.firstmention.uk/mcp' --transport streamable-http
```

### Hermes

```yaml
mcp_servers:
  uk-firstmention-api-automaton:
    url: "https://api.firstmention.uk/mcp"
```

### Netclaw

```json

    "uk-firstmention-api-automaton": {
      "Transport": "http",
      "Url": "https://api.firstmention.uk/mcp"
    }
  }
}
```

### Vellum

```bash
assistant mcp add uk-firstmention-api-automaton -t streamable-http -u 'https://api.firstmention.uk/mcp'
```

### Other

```json
{
  "mcpServers": {
    "uk-firstmention-api-automaton": {
      "type": "http",
      "url": "https://api.firstmention.uk/mcp"
    }
  }
}
```

The mcpServers block is a cross-client convention. Remote transports vary, so check your client's docs.
