Features

75 tools across 11 domains:

• DNS — Record management (A, AAAA, CNAME, MX, TXT, SRV, CAA, NS), batch operations
• Zones — Zone listing, settings, SSL/TLS configuration, cache management
• Tunnels — Cloudflare Tunnel creation, configuration, and ingress management
• WAF — Ruleset management, custom firewall rules, rate limiting
• Zero Trust — Access application CRUD (create/delete), policies (create/delete), identity providers (create/delete), Gateway status
• Security — Security event analytics, IP access rules, DDoS configuration, Security Center insights
• Workers KV — Namespace management, key-value read/write/delete, key listing
• Workers — Script deployment, route management
• Worker Secrets — Secret management (names only, values never exposed)
• Worker Analytics — Invocation metrics, CPU time, error rates via GraphQL
• R2 Storage — Bucket management, object listing and metadata, custom domains, location hints

Quick Start

npm install
cp .env.example .env   # Edit with your Cloudflare API token
npm run build
node dist/index.js     # stdio transport for MCP

Claude Code Integration

Add to .mcp.json in your project root:

{
  "mcpServers": {
    "cloudflare": {
      "command": "node",
      "args": ["/path/to/mcp-cloudflare/dist/index.js"],
      "env": {
        "CLOUDFLARE_API_TOKEN": "your-api-token-here",
        "CLOUDFLARE_ACCOUNT_ID": "your-account-id"
      }
    }
  }
}

Configuration

Variable	Required	Default	Description
CLOUDFLARE_API_TOKEN	Yes	—	Cloudflare API Token (with appropriate permissions)
CLOUDFLARE_ACCOUNT_ID	No	—	Cloudflare Account ID (required for account-level operations)
CLOUDFLARE_TIMEOUT	No	30000	Request timeout in milliseconds
NAS_VAULT_ADDR	No	—	HashiCorp Vault URL, enables Vault AppRole loading (see below)
NAS_VAULT_ROLE_ID	No	—	Vault AppRole role_id
NAS_VAULT_SECRET_ID	No	—	Vault AppRole secret_id
NAS_VAULT_KV_MOUNT	No	kv	Vault KV v2 mount path

Loading Secrets from HashiCorp Vault (AppRole)

If you run a central Vault instance, mcp-cloudflare can fetch its credentials at startup via AppRole instead of passing them through the MCP config:

export NAS_VAULT_ADDR=https://vault.example.com
export NAS_VAULT_ROLE_ID=<role-id>
export NAS_VAULT_SECRET_ID=<secret-id>
# optional — defaults to "kv"
export NAS_VAULT_KV_MOUNT=kv

The loader reads KV v2 at <mount>/data/cloudflare/api and expects two keys: api_token and account_id. Example Vault write:

vault kv put kv/cloudflare/api \
  api_token=your-api-token-here \
  account_id=00000000000000000000000000000000

Precedence: process.env (explicit) > Vault. If NAS_VAULT_ADDR is unset the loader is a silent no-op — the server behaves exactly as before. On any Vault error (network, auth, missing path), a single-line warning is written to stderr and the server falls back to whatever env vars are already set.

Security: secret values are never logged. Only the KV path name and a populated-count appear in stderr diagnostics. Uses the global fetch (Node 20+) — no new runtime dependencies.

API Token Permissions

Create an API Token at dash.cloudflare.com/profile/api-tokens with the following permissions based on what you need:

• DNS: Zone > DNS > Edit
• Zone settings: Zone > Zone Settings > Edit
• Cache purge: Zone > Cache Purge > Edit
• Tunnels: Account > Cloudflare Tunnel > Edit
• WAF: Zone > Firewall Services > Edit
• Zero Trust: Account > Access: Apps and Policies > Edit
• Security events: Zone > Analytics > Read
• Workers KV: Account > Workers KV Storage > Edit
• Workers: Account > Worker Scripts > Edit
• R2: Account > R2 Storage > Edit

Multi-Zone Support

All zone-scoped tools accept a zone_id parameter that can be either:

• A 32-character hex zone ID (e.g., 00000000000000000000000000000001) — used directly
• A zone name / domain (e.g., example.com) — resolved automatically via the Cloudflare API

This allows managing multiple zones by name without needing to look up IDs manually.

Tools

Tools documentation is coming in v1 as tool modules are implemented. See docs/api-reference.md for the planned API endpoint mapping.
