Verifies any brand name across USPTO trademarks, domains, and 14 social handles. Sub-3s. Citation-backed. The verification layer LLMs call before suggesting a brand name. When a user asks Claude, Cursor, ChatGPT, or any LLM-driven workflow for naming help, the model invokes Etymolt silently — verifying against USPTO trademarks, TTAB precedent, domain availability across 8 TLDs, and live handle probes across 14 social platforms — in 3 seconds, with every flag traced. **Three tools, anonymous-first** (first 5 calls per IP free, no API key required): - `verify_brand_name` — 5-axis verdict on one candidate (PROCEED / DUE_DILIGENCE / ITERATE / ABANDON, 0–100 score across trademark + domain + cultural + sound symbolism + pronunciation). 8–12s. - `compare_brand_names` — side-by-side ranking of 2–5 finalists. ~5s. - `get_naming_methodology` — public methodology document. Instant, no quota. **Data substrate**: 12.7M live US trademarks (USPTO, refreshed daily) + 647K TTAB proceedings with DuPont-factor extraction. UKIPO full + WIPO Madrid partial. Verisign RDAP across 8 TLDs. Live handle probes across 14 platforms. Cultural meaning across 20 markets. Public methodology at https://etymolt.com/methodology. Every response carries a `disclaimer` field — Etymolt is a clearance signal, not legal advice.

MCP readiness

B · 84/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here C+, 70.0/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ

Valid MCP handshake	10/10	initialize and tools/list both answered.
Live MCP endpoint	25/25	Endpoint answers the MCP initialize handshake (2254 ms).
Protocol revision	5/10	Speaks MCP 2025-03-26, 3 revision(s) behind 2026-07-28.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	15/15	31/31 probes succeeded over 30 days (100%).
Tool declaration	10/10	Lists 3 tool(s) with descriptions.
Verified identity	5/10	Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Auth declaration	2/5	Declares credential scheme: smithery_api_key.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Responsive (2254 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 53,039 reachable MCP servers in our daily snapshot (2026-11-12 06:46 UTC). Display only; it does not change search order.

Readiness: Higher than 75% of peers; This listing 84 · peer median 81
Latency: Faster than 39% of peers; This listing 424 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Protocol revision −5 — Support the current protocol revision.
Now: Speaks MCP 2025-03-26, 3 revision(s) behind 2026-07-28.
Verified identity −5 — Claim the listing and prove control of its domain.
Now: Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Auth declaration −3 — State how to authenticate (an auth scheme, or that none is needed).
Now: Declares credential scheme: smithery_api_key.
