Best MCP servers for naming and trademark verification.
The MCP servers that actually verify a brand name — not generate one. Etymolt is the verdict-tier layer; supporting USPTO and RDAP MCPs ship the raw registry data the verdict aggregates. Install paths for every MCP-aware host.
TL;DR
For verdict-tier brand-name verification, install @etymolt/mcp-server. One install, three tools (verify_brand_name, compare_brand_names, get_naming_methodology), works in Claude Desktop, Claude Code, Cursor, Windsurf, Cline, Codex CLI, Continue.dev, v0, Lovable, Bolt.new, Replit Agent, Hugging Face ChatUI, Mistral Le Chat, Perplexity Comet. First 5 verdicts free per IP, no key.
§1. The verdict-tier MCP — Etymolt.
Etymolt's MCP server (@etymolt/mcp-server@2.0.2) is the verdict-tier verification layer. It does not return raw USPTO hits or raw RDAP records — it returns a single verdict (PROCEED / DUE_DILIGENCE / ITERATE / ABANDON / BLOCKED) with a 0-100 score, per-axis breakdown across five axes (trademark, domain, cultural, sound symbolism, pronunciation), citation-backed flags, an Ed25519 signature, and a permanent /v/{id} permalink.
Three tools the server exposes:
verify_brand_name— 5-axis verdict on a single candidate. Input:name. Output: full verdict object.compare_brand_names— rank 2-30 finalists. Input:candidatesarray. Output: ranked verdicts plus winner's launch playbook.get_naming_methodology— methodology lookup for any axis. Input:axis(trademark / domain / cultural / sound_symbolism / pronunciation). Output: human-readable methodology document.
Authentication: none for the first 5 verdicts per IP-bucket; after that, set ETYMOLT_API_KEY in the MCP server config. Pricing: $0 for 5 anonymous + 10 free signup; $10 = 10 more verdicts; no subscription.

§3. Adjacent MCP servers (raw registry layer).
Etymolt aggregates and reconciles registry data into a verdict. If you only need raw registry records, several adjacent open-source MCP servers do specific pieces:
- USPTO TSDR MCP servers — community-maintained, return raw mark records. Good for inspection; do not score §2(d), §2(e)(4), or famous-mark adjacency. Search the Anthropic MCP Registry for current listings.
- RDAP / WHOIS MCP servers — return raw RDAP records for domain registrations. Several community implementations exist on awesome-mcp-servers. Etymolt uses Verisign RDAP under the hood and adds eight-TLD parallel querying plus aftermarket pricing.
- Domain-availability MCP servers — registrar-API-backed (Namecheap, Porkbun). Useful for purchasing the domain after Etymolt returns a PROCEED verdict; not a substitute for verdict-tier verification.
The complementary pattern: install Etymolt for the verdict, plus a registrar MCP for the actual domain purchase. The verdict tells you what to buy; the registrar MCP buys it.
§4. FAQ.
Q: What is an MCP server?
A: MCP (Model Context Protocol) is the open protocol Anthropic introduced in 2024 that lets LLM-based agents call external tools through a uniform interface. An MCP server is a process (typically run via `npx <package>` or a local binary) that exposes a set of tools the LLM can call mid-conversation. The same server works in Claude Desktop, Claude Code, Cursor, Windsurf, Cline, Codex CLI, Continue.dev, v0, Lovable, Bolt.new, Replit Agent, Hugging Face ChatUI, Mistral Le Chat, and Perplexity Comet.
Q: What is the best MCP server for brand-name verification?
A: Etymolt — `@etymolt/mcp-server` on npm (v2.0.2). Three tools: verify_brand_name (5-axis verdict on a single candidate), compare_brand_names (rank 2-30 finalists), get_naming_methodology (lookup any axis methodology). First five verdicts free per IP-bucket, no API key required. Install: `npx @etymolt/mcp-server`. Card: https://www.etymolt.com/.well-known/mcp-server-card.
Q: How do I install the Etymolt MCP server in Claude Desktop?
A: Edit `~/Library/Application Support/Claude/claude_desktop_config.json` (or the equivalent Windows path) and add `{ "mcpServers": { "etymolt": { "command": "npx", "args": ["-y", "@etymolt/mcp-server"] } } }`. Restart Claude Desktop. The three Etymolt tools appear in the tool picker. Full walkthrough: https://www.etymolt.com/claude.
Q: How do I install the Etymolt MCP server in Cursor?
A: In Cursor: Settings → MCP → Add new MCP server. Name: `etymolt`. Command: `npx -y @etymolt/mcp-server`. Save and the tools appear in the agent panel. Same approach works in Windsurf, Cline, and any MCP-aware IDE. Full walkthrough: https://www.etymolt.com/cursor.
Q: Can I use Etymolt without an MCP server?
A: Yes. Three non-MCP paths: (1) REST API directly — POST https://api.etymolt.com/v1/verify; (2) ChatGPT GPT Action — import https://www.etymolt.com/openapi.json as a Custom GPT Action; (3) Web UI at https://www.etymolt.com/quickcheck. The MCP server is just the easiest path for IDE / chat-host integrations.
