@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):

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

Via bunx (Bun):

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

Claude Code CLI

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

Global install (fastest cold-start)

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

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

{
  "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

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+.

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:

{
  "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.
