Porkbun MCP Server (official)

The official MCP server from Porkbun, built and maintained by Porkbun (by Owen Borseth, Porkbun's CTO). It is published on npm as @porkbunllc/mcp-server and hosted by Porkbun at https://mcp.porkbun.com/mcp. Other "Porkbun MCP" projects on GitHub and in MCP directories are community wrappers around the public API; they are not made or supported by Porkbun. In the official MCP Registry it is listed as com.porkbun/mcp, a name the registry grants only to whoever proves control of porkbun.com; community projects appear under io.github.* names.

A Model Context Protocol server that exposes the Porkbun v3 API as native tools for AI agents — Claude Desktop, Cursor, Cline, and any other MCP-compatible client.

Setup guide, client configs and the full tool list: porkbun.com/mcp

No install: use the hosted connector. Porkbun runs this server at https://mcp.porkbun.com/mcp. Add that URL as a custom connector in ChatGPT or Claude (or claude mcp add --transport http porkbun https://mcp.porkbun.com/mcp in Claude Code), sign in to Porkbun and approve. No API key to copy. Steps per client: Connect ChatGPT or Claude. How it is deployed: deploy/README.md. The ChatGPT and Claude directory listings use a narrower variant, /mcp/no-purchases (no tool that spends money or returns a secret); it changes which tools are offered, not what a connection may do.

Status: full Porkbun v3 coverage (domains, DNS, SSL, hosting, webhooks; current version on the npm badge above). Also runs hosted at https://mcp.porkbun.com/mcp for ChatGPT and Claude, with sign-in instead of API keys. Provisions Cloud for WordPress and mints WordPress REST API credentials so an agent can manage the site it just created. Moves domains to a customer's own Cloudflare account and then manages those records, the proxy and zone settings. An isolated sandbox: a pk1_sb_ key runs every tool against a simulated environment with fake credit — no real registry actions, DNS changes or charges — and still delivers signed webhooks. A credential-free mock server returns schema-accurate example responses for any endpoint.

What's included

Read tools (free, no spend, no state changes)

The list_doc_topics / read_doc / search_docs tools let an agent ground itself in Porkbun's own documentation (the /llms Markdown surface) mid-conversation — no web browsing required, and no API credentials needed. You can add the server purely to research the API, then supply keys when you're ready for live operations.

Account funding (charges a saved card, not credit)

Domain lifecycle writes (spend account credit)

Domain settings writes (free)

DNS / DNSSEC / URL-forwarding / glue writes (free)

Secure Static Hosting

Cloud for WordPress

create_hosting with a CLOUDWORDPRESS… sku provisions a managed WordPress site instead of static hosting (the file tools don't apply — manage it through WordPress).

Cloudflare connect (move domains to the customer's own Cloudflare account)

Connecting the Cloudflare account itself is a human step — Cloudflare's consent screen has to be completed in a browser — so get_cloudflare_connection hands you a URL to show your user, then acts as the poll target. Everything after that is automated.

• get_cloudflare_connection — connected or not, and where to send the human if not (poll this)
• list_cloudflare_inventory — every domain with its eligibility and a plain-English reason
• preview_cloudflare_move — exactly which records a move would copy or drop, queueing nothing
• connect_domains_to_cloudflare — queue one or many (async: returns queued, never connected)
• get_cloudflare_queue / get_cloudflare_domain_status — progress, and the audit trail
• retry_cloudflare_domain / rollback_cloudflare_domain — re-queue a failure, or restore Porkbun nameservers
• get_cloudflare_records / create_cloudflare_record / edit_cloudflare_record / delete_cloudflare_record — manage DNS in the zone that actually answers once a domain has moved
• set_cloudflare_proxy — turn the orange cloud on or off, per record (a move always imports DNS-only, on purpose)
• get_cloudflare_zone — Cloudflare's own zone state, plus nameserver-drift detection
• get_cloudflare_zone_settings / set_cloudflare_zone_settings — SSL mode and friends
• disconnect_cloudflare — forget the grant (domains already moved keep working)

Sandbox / test mode

Use a sandbox API key (public key prefixed pk1_sb_, secret sk1_sb_) and every tool above runs against an isolated test environment — same server, you just swap the key. Registrations, renewals, transfers, DNS, contacts, glue, and DNSSEC are all simulated against a separate sandbox datastore: no real registry actions, no DNS changes, no certificates, and no charges. Your sandbox account starts with fake account credit, availability/pricing reflect the real catalog, and every response includes "sandbox": true. Create a sandbox key on porkbun.com/account/api. Or mint one instantly with create_sandbox_key — no signup, no credentials. (Hosting and email endpoints aren't simulated and return SANDBOX_UNSUPPORTED with a sandbox key.)

Mock server (no credentials)

mock_call returns a schema-accurate example response for any endpoint with no key required — nothing to set up. Pass a path like domain/listAll or dns/create/example.com (omit it to list every mockable endpoint), or set error: true for the error shape. Responses touch no datastore and match the live API's shape exactly, so you can build and test client code before you have any credentials.

Webhook writes (free)

Porkbun POSTs a signed JSON payload to your endpoint when subscribed events occur (domain.registered, domain.renewed, domain.transfer.completed, domain.expiring, dns.record.created|updated|deleted). Verify the X-Porkbun-Signature header — it's sha256= + HMAC-SHA256 of {timestamp}.{rawBody} keyed by the endpoint secret, where {timestamp} is the X-Porkbun-Webhook-Timestamp header.

Claude plugin

plugin/ is a Claude plugin (claude.ai, Cowork and Claude Code): the hosted connector at https://mcp.porkbun.com/mcp/no-purchases plus two skills, publish-website (publish a site Claude builds to Porkbun Secure Static Hosting instead of giving upload steps) and change-dns-safely. It holds no code. To try it in Claude Code: claude --plugin-dir ./plugin. Raise version in plugin/.claude-plugin/plugin.json with every change to the folder.

Install

You'll need Node.js 18 or newer.

npx -y @porkbunllc/mcp-server

This downloads and runs the latest version on demand. No global install needed.

Configure your MCP client

Claude Desktop

Add this to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "porkbun": {
      "command": "npx",
      "args": ["-y", "@porkbunllc/mcp-server"],
      "env": {
        "PORKBUN_API_KEY": "pk1_your_public_key_here",
        "PORKBUN_SECRET_API_KEY": "sk1_your_secret_key_here"
      }
    }
  }
}

Restart Claude Desktop. Porkbun tools should appear in the tool picker.

Docs-only, no keys: the documentation tools (search_docs, read_doc, list_doc_topics) work without credentials, so you can omit the env block entirely to use the server just for API research. The authenticated tools return a clear "set PORKBUN_API_KEY" message until you add keys.

Cursor / Cline / Continue

Most MCP-aware editors use a similar mcpServers config block. See your client's documentation for the exact location.

Get API keys

Create API keys at porkbun.com/account/api. You'll need both the public key (pk1_…) and the secret key (sk1_…).

By default, API access is opt-in per domain. To use the API to manage all your domains, enable the "Opt In All Domains" toggle in the same settings page. Otherwise you'll need to enable API access for each domain individually under Domain Management.

Recommended: scope the key to your agent

Each API key supports two optional restrictions, set via the gear icon next to the key in porkbun.com/account/api:

• Allowed IPs — one entry per line; supports bare IPv4/IPv6 plus CIDR ranges (198.51.100.0/24, 2001:db8::/32). Requests from other IPs fail with HTTP 403 IP_NOT_ALLOWED before any other check runs.
• Allowed domains — one entry per line, exact match. Operations against domains not in the list fail with HTTP 403 DOMAIN_NOT_ALLOWED.

Empty fields = no restriction (matches current behavior). When you give an MCP server a key, the recommended pattern is:

1. Create a fresh key dedicated to the agent (not your master key).
2. List the specific domains the agent should manage.
3. If you know the agent's egress IP, list it too.

The blast radius of an accidentally-leaked key drops to "operations on these domains from this IP" instead of "anything on the account."

Environment variables

Local development

git clone https://github.com/oborseth/Porkbun-MCP.git
cd Porkbun-MCP
npm install
npm run build
npm start          # or: node dist/index.js

The server speaks JSON-RPC 2.0 over stdio. Smoke test from a shell:

(printf '%s\n' \
  '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}' \
  '{"jsonrpc":"2.0","method":"notifications/initialized"}' \
  '{"jsonrpc":"2.0","id":2,"method":"tools/list"}') \
  | PORKBUN_API_KEY=pk1_… PORKBUN_SECRET_API_KEY=sk1_… node dist/index.js

Money parameters are in cents, and say so

Every money parameter ends in _cents and takes integer US cents: cost_cents: 1108 is $11.08, amount_cents: 803 is $8.03. The unit is in the name because some clients build their approval prompt from the raw arguments, and a bare amount: 803 was shown to a user as "$803". The old names (cost, amount, threshold, acknowledged_cost, price_min, price_max) are still accepted in the same unit; sending both names with different values is refused before anything reaches the API.

Reliability

Write operations automatically attach a per-call Idempotency-Key header. Retried calls within 24 hours return the cached response, so your agent can safely retry on network errors without double-charging or double-registering.

Privacy

This MCP server is a thin client that runs locally (on your machine, or wherever you host it) and relays your requests directly to the Porkbun API over HTTPS. It does not add any data collection of its own:

• What it sends, and to whom. Your API key/secret and the arguments of each tool call are sent only to https://api.porkbun.com (and, for the credential-free documentation and mock tools, to https://porkbun.com). Nothing is sent anywhere else.
• Storage. The server keeps your credentials in memory for the lifetime of the process (read from environment variables); it does not write them to disk, log them, or cache your data.
• Hosted connector. At mcp.porkbun.com the same code runs on Porkbun's infrastructure. It holds no API keys: each request carries the user's OAuth access token, which is forwarded to the Porkbun API and kept in memory only briefly (a 30-second validity cache). Request logs record method, path, status and timing, never tokens or request bodies.
• No telemetry. There is no analytics, tracking, or third-party sharing performed by this connector.
• Data you access through it (domains, DNS, contacts, billing, etc.) is your Porkbun account data, handled by Porkbun under its policy.

Full data-handling, retention, third-party, and contact details are in Porkbun's privacy policy: https://porkbun.com/legal/agreement/privacy_policy
