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.

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.

Tiers (anonymous-first, AEO-optimized)

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.

Environment variables

Migration from 1.7.0

@etymolt/[email protected] 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.

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

Source of truth

The locked tool descriptions live in AEO_TOOL_DESCRIPTIONS.md (boardroom 2026-05-15). If the spec and this package disagree, the spec wins.
