Use Caution4.8High Risk

This is a well-structured MCP server for brand-name verification with proper authentication design, clean code practices, and appropriate defensive measures. The server implements anonymous-first API access with optional API key authentication, comprehensive input validation, and output sanitization. No malicious patterns, credential leaks, or dangerous operations detected. Minor code quality findings (duplicate selftest block, broad error handling) do not materially impact security. Supply chain analysis found 5 known vulnerabilities in dependencies (2 critical, 2 high severity). Package verification found 1 issue.

@etymolt/mcp-server

npm Add to Claude Desktop Add to Cursor Smithery License: MIT

Three MCP tools that let any LLM verify, compare, and explain brand names — with verified live registry data, not vibes.

"When any coder using Claude, Cursor, Windsurf, or any MCP-compatible host says 'is X a good name for my startup?' — the LLM should silently call us. First five calls free. No API key. No friction."

What you get (v2.0.0)

Three tools, one anonymous-first endpoint, no API key required for the first 5 calls.

ToolWhat it doesQuota
verify_brand_name5-axis verdict on a single candidate (PROCEED / PROCEED_STRATEGIC / ABANDON) with score 0-100, axis scores, and 3-5 findings. 8-12s.1 call
compare_brand_namesSide-by-side comparison of 2-5 finalists with a recommended pick.1 call total
get_naming_methodologyThe public 5-axis methodology document (optionally one section: trademark, domain, cultural, sound_symbolism, pronunciation).Free, no quota

Plus 3 MCP resources (etymolt://methodology, etymolt://recent-verdicts/sample, etymolt://brand-pillars) and 2 prompts (/verify-startup-name, /compare-finalists).

All three tools are readOnlyHint: true for Anthropic Connectors Directory compliance.

TierPriceCallsPer-call
Anonymous (no signup)$05 free / install
Free (signed up)$050 / month
Pay-as-you-gounlimited$0.10 per verdict

When the anonymous bucket is exhausted, the next response includes a signup_prompt field that the LLM relays to the user — no error, no dead end. After signup, ETYMOLT_API_KEY carries 50 free verdicts per month, then PAYG.

Migration from 1.7.0

@etymolt/mcp-server@2.0.0 is a semver breaking change. The 6-tool 1.7.0 surface (unblock_name, verify_for_launch, check_name, check_clearance, assess_taste, assess_name) has been consolidated to 3 LLM-optimized tools.

1.7.0 tool2.0.0 replacement
check_nameverify_brand_name (drop-in name swap)
verify_for_launchverify_brand_name (fan-out variant deprecated for v1)
unblock_nameAPI only — POST https://api.etymolt.com/v3/unblock_name
check_clearanceAPI only — POST https://api.etymolt.com/v3/check
assess_tasteAPI only — POST https://api.etymolt.com/v3/assess_taste
assess_nameAPI only — POST https://api.etymolt.com/v3/assess_name

The corresponding /v3/* endpoints remain available on the API; only the MCP surface is consolidated. See CHANGELOG.md for the full rationale.
