v2.3.0 — paywall front-door + retention + prompts/resources

DC Hub MCP Server v2.3.0

Real improvements since v2.2.8 (this release also tags the previously-untagged 2.2.9 work).

Paywall front door

• The $5 / 1,000-query pack is now the #1 offer, with the front-door sweep finished across all remaining surfaces.

Anonymous taste flow

• Anonymous callers get 3 free results, then a sell — free key (10/day) · $5 / 1,000-query pack · $9/mo Starter (200/day).

Smarter gating + retention

• Depleted-pack re-up nudge leads with "top up $5"; gateway credit gate and unlock_more_data lead with the $5 pack.
• Flagship free-taste cap re-keyed to IP and lowered to 2 (the retention fix).
• claim_free_key now surfaces a get_changes return-loop hook so agents come back.

In-tool upsell

• Land & Power map CTA added to the map-data tools and the trial-taste path.

Discovery / UX

• 6 new guided MCP prompts + 4 citable resources, one-click install badges, and a ⭐ star CTA near the top of the README.

Ops / automation

• Daily registry-rank + drift monitor workflow; Tier-3 presence kit with ready-to-post drafts + checklist.
