# @archawat/mcp-cloudflare

Model Context Protocol (MCP) server for managing Cloudflare DNS across multiple zones (domains) from a single API token. Built for bulk workflows — flipping proxy on/off across many records, auditing DNS across zones, and batched record updates.

## Features

- **Multi-zone from one token** — pass a domain name like `"example.com"` and the server resolves the zone for you. Zone IDs also accepted.
- **Bulk operations** — `bulk_toggle_proxy`, `bulk_update_dns_record`, and `bulk_list_dns_records` run concurrently and share a per-invocation zone-ID cache so repeated zones don't cost extra lookups.
- **Safe defaults** — new A/CNAME records are created with `proxied: false` (DNS-only, grey cloud). Proxy is opt-in.
- **Auto-pagination** — `list_dns_records` fetches every page in parallel unless you ask for a specific one.

## Install

No local install required — use `npx` or `bunx` to run it on demand.

### Claude Code / Claude Desktop (`.mcp.json`)

Via `npx` (Node):

```json
{
  "mcpServers": {
    "cloudflare": {
      "command": "npx",
      "args": ["-y", "@archawat/mcp-cloudflare"],
      "env": { "CLOUDFLARE_API_TOKEN": "cf-token-here" }
    }
  }
}
```

Via `bunx` (Bun):

```json
{
  "mcpServers": {
    "cloudflare": {
      "command": "bunx",
      "args": ["-y", "@archawat/mcp-cloudflare"],
      "env": { "CLOUDFLARE_API_TOKEN": "cf-token-here" }
    }
  }
}
```

### Claude Code CLI

```bash
claude mcp add cloudflare -s user \
  -e CLOUDFLARE_API_TOKEN="cf-token-here" \
  -- npx -y @archawat/mcp-cloudflare
```

### Global install (fastest cold-start)

```bash
npm install -g @archawat/mcp-cloudflare
# or: bun add -g @archawat/mcp-cloudflare
```

The global bin is named `mcp-cloudflare` (unscoped), so:

```json
{
  "mcpServers": {
    "cloudflare": {
      "command": "mcp-cloudflare",
      "env": { "CLOUDFLARE_API_TOKEN": "cf-token-here" }
    }
  }
}
```

## API Token

Create a Cloudflare token at <https://dash.cloudflare.com/profile/api-tokens> with:

- `Zone:Read`
- `Zone:DNS:Edit`

Scope the token to the zones you want to manage, or grant "All zones".

## Tools

| Tool | Purpose |
|---|---|
| `list_zones` | Discover which domains the token can manage. |
| `list_dns_records` | List records in a zone; auto-paginates across all pages unless `page` is set. |
| `bulk_list_dns_records` | List records across many zones in one call. Concurrent per-zone. |
| `create_a_record` | Create an A record. `proxied` defaults to `false`. |
| `create_cname_record` | Create a CNAME record. `proxied` defaults to `false`. |
| `create_txt_record` | Create a TXT record (SPF, DKIM, DMARC, domain verification). |
| `create_mx_record` | Create an MX record for mail routing. `priority` required. |
| `toggle_proxy` | Flip proxy on/off by record ID, or by name (+ optional type). |
| `bulk_toggle_proxy` | Flip proxy for many records in one call (shared `proxied` value). |
| `update_dns_record` | Patch `content`, `ttl`, `proxied`, or `comment` on a record. |
| `bulk_update_dns_record` | Patch many records in one call with per-item fields. |
| `delete_dns_record` | Delete a record by ID. Destructive. |

All tools accept either a domain name (`"example.com"`) or a 32-char zone ID as the `zone` argument.

### Result shape

Responses are plain text — TSV for lists, one-liners for mutations — to keep token usage low. A single failure in a bulk call doesn't abort the batch.

`list_dns_records`:

```
Total: 2
id	type	name	content	proxied	ttl
abc123	A	www.example.com	1.2.3.4	true	1
def456	CNAME	api.example.com	example.com	false	300
```

`create_*` / `update_dns_record` / `toggle_proxy` / `delete_dns_record`:

```
OK: dns_record abc123 created (www.example.com)
```

`bulk_list_dns_records`:

```
Zones: 2 (succeeded: 1, failed: 1)
FAIL: other.com - No zone found for 'other.com'

Records: 1
zone	id	type	name	content	proxied	ttl
example.com	abc123	A	www.example.com	1.2.3.4	true	1
```

`bulk_toggle_proxy` / `bulk_update_dns_record`:

```
Succeeded: 1, Failed: 1
OK: example.com/abc123 toggled (www.example.com)
FAIL: other.com/www.other.com - No proxyable record found for 'www.other.com'.
```

Errors return `Failed: <message>` with `isError: true`. Bulk tools also set `isError: true` whenever any item fails, while still returning every result.

## Development

Requires Bun (recommended) or Node 18+.

```bash
bun install
bun run dev         # run src/index.ts with --watch
bun run start       # run src/index.ts once
bun run typecheck   # tsc --noEmit
bun run build       # emit dist/ for publishing
```

To run the dev copy as the MCP server instead of the published package, point `.mcp.json` at your local build:

```json
{
  "mcpServers": {
    "cloudflare": {
      "command": "bun",
      "args": ["/abs/path/to/mcp-cloudflare/src/index.ts"],
      "env": { "CLOUDFLARE_API_TOKEN": "cf-token-here" }
    }
  }
}
```

The server speaks stdio — your MCP client spawns the process and communicates over stdin/stdout.
