@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

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.
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.

Bulk result shape

Bulk tools return per-item results; a single failure doesn't abort the batch:

{
  "succeeded": 10,
  "failed": 1,
  "results": [
    { "zone": "example.com", "ok": true,  "record": { "id": "…", "proxied": true } },
    { "zone": "other.com",   "ok": false, "error": "No proxyable record found for 'www.other.com'." }
  ]
}

isError: true is set on the tool response 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.
