Install Bloomfilter in Claude Code, Cursor or VS Code

Runs npx -y @bloomfilter/mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add bloomfilter -- npx -y @bloomfilter/mcp-server
Add to Cursor

What the publisher says

From the Bloomfilter repository's README, as published. We do not edit it. Read it on GitHub

@bloomfilter/mcp-server

MCP server for Bloomfilter, search & register domain names and manage DNS records from AI agents.

Bloomfilter is a domain registration and configuration API that uses x402 for payments. Point your AI agent at the Bloomfilter API, give it a wallet with some USDC, and it can autonomously search, register, and configure domains.

No login, no credit card, no dashboard. Just HTTP requests and a crypto wallet.

This MCP server wraps the Bloomfilter API so that any MCP-compatible client (Claude Desktop, Cursor, Windsurf, custom agents, etc.) can use it as a tool provider.

Quick Start

BLOOMFILTER_PRIVATE_KEY=0x... npx @bloomfilter/mcp-server

The server communicates over stdio (JSON-RPC). It's meant to be launched by an MCP client, not run standalone.

Configuration

Add this JSON to your MCP client's config file:

{
	"mcpServers": {
		"bloomfilter": {
			"command": "npx",
			"args": ["-y", "@bloomfilter/mcp-server"],
			"env": {
				"BLOOMFILTER_PRIVATE_KEY": "0x..."
			}
		}
	}
}

Config file location by client

Any MCP-compatible client that supports stdio servers will work.

Environment variables

Without a private key, only searchdomains and getpricing work. Everything else requires a wallet.

Tools

The server exposes 10 tools:

Free (no wallet needed)

  • searchdomains:** Check if a domain is available and get pricing. Searches across multiple TLDs at once.
  • getpricing:** Get registration, renewal, and transfer pricing for one or all supported TLDs.

Authenticated (wallet required)

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
