Brand-name verification MCP — five-axis signed verdicts for AI-generated names.
Brand-name verification MCP — five-axis signed verdicts for AI-generated names.
The Etymolt MCP server is well-structured with thoughtful security practices, particularly around sanitization of user input and API response data to prevent prompt injection and markdown injection attacks. Authentication is optional but appropriately designed around an anonymous-first quota model. Permissions align with the server's purpose (brand-name verification via HTTP API), and there are no critical vulnerabilities, malicious patterns, or hardcoded secrets. Minor code quality observations noted but do not materially impact security. Supply chain analysis found 5 known vulnerabilities in dependencies (2 critical, 2 high severity). Package verification found 1 issue.

Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.
This plugin requests these system permissions. Most are normal for its category.

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."
Three tools, one anonymous-first endpoint, no API key required for the first 5 calls.
| Tool | What it does | Quota |
|---|---|---|
verify_brand_name | 5-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_names | Side-by-side comparison of 2-5 finalists with a recommended pick. | 1 call total |
get_naming_methodology | The 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.

| Tier | Price | Calls | Per-call |
|---|---|---|---|
| Anonymous (no signup) | $0 | 5 free / install | — |
| Free (signed up) | $0 | 50 / month | — |
| Pay-as-you-go | — | unlimited | $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.
| Var | Default | Notes |
|---|---|---|
ETYMOLT_API_URL | https://api.etymolt.com | Override for self-hosted or staging. |
ETYMOLT_API_KEY | (unset) | Without it, calls go through the anonymous bucket. |
@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 tool | 2.0.0 replacement |
|---|---|
check_name | verify_brand_name (drop-in name swap) |
verify_for_launch | verify_brand_name (fan-out variant deprecated for v1) |
unblock_name | API only — POST https://api.etymolt.com/v3/unblock_name |
check_clearance | API only — POST https://api.etymolt.com/v3/check |
assess_taste | API only — POST https://api.etymolt.com/v3/assess_taste |
assess_name | API 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.
The locked tool descriptions live in AEO_TOOL_DESCRIPTIONS.md (boardroom 2026-05-15). If the spec and this package disagree, the spec wins.
