One bearer token. Claude Code, Cursor, or any MCP client. A free 60-minute demo token below, no login.

Watch an agent use it.

One Copywriter agent, one MCP connection. It reads Paleo Pro's record through get_brand_dna_public and drafts lines only Paleo Pro would say. A recreation of a real session, shape for shape: every request and response is exactly what the wire returns.

The session below ran against the live gateway with a free demo token. Mint your own in the next section and make the same three calls.

Draft the ad headline and one supporting line for Paleo Pro. Sound like the brand, not like the category.

Four ingredients. Zero things you can’t pronounce.

Grass-fed, nose-to-tail nutrition in one scoop — the way your ancestors ate, minus the campfire. Read the label. That’s the whole pitch.

Mint first. The call runs from this page with your token, against the same endpoint your client will use.

Try it now. No login.

A real token, minted here, that reads 3 showcase brands for 60 minutes. Mint, paste, and make the first call before you have told us your name.

The perimeter is honest machinery: 3 active tokens per IP, fail-closed · 5 mints an hour · a kill switch we can flip. What you get is the public projection: 5 of the 25 tools, read-only.

Same agent. Same brief. One knows the brand.

Pick a brand and sweep the divider. The generic run could belong to anyone. The grounded run was written from that brand's extracted record: its wedge, its tone, its banned words.

Four doors in.

Skills your agent installs, personas it becomes, a gateway it connects to, or an API it calls raw — pick the door that matches how you already work.

01

Skills

MIT-licensed marketing skills your agent installs and runs locally. The catalog grows as skills ship.

Agents

03

MCP

API

real contract · the response shape of the spend-adjacent write tool · a checkout URL for your human, never a charge

Agents read. Humans spend.

Every tool but one is read-only. The one that writes can queue work and hand back a checkout or intake URL, and it is architecturally unable to complete a payment on its own.

  • Entitlement is live.Your token's tier resolves against your subscription on every call, fail-closed. Paste once; upgrades and lapses take effect on the next request.
  • Every call is audited. One audit row per call, with free text redacted before hashing, so the trail can never be read back into your prompts.
  • Tokens rotate with a 24-hour overlap. The old secret keeps working while you swap the new one in. Revocation is immediate.

25 tools, real names, real limits.

The registry, not a roadmap. Your token's own tools/list returns exactly the set your audience and tier grant; nothing here is padded.

The 25 tools, by family

Brand DNA & access

The verified record an agent writes from, plus the tools that read the wire itself.

  • pingpublicThe smoke tool. Verifies gateway wiring end to end.
  • get_token_contextpublicWhat this token can reach: brands, scopes, tier, expiry.
  • ask_brandpublicAsk a question; get back the canonical facts that answer it, and the gaps.
  • get_brand_dnapublicThe canonical typed record: identity, positioning, voice, pillars.
  • get_brand_dna_publicpublicA bounded public projection. Competitive intel is never included.
  • get_brand_productspublicPer-SKU product details: ingredients, claims, dimensions, URL.
  • get_verified_facts_statusinternalThe review-queue state: active, proposed, gaps.
  • get_marketing_truthinternalThe always-current product and strategy truth feed.

Design system

The same design contracts the Jinn products render from, read-only.

  • get_brand_design_mdpublicYour brand's agent-readable DESIGN.md.
  • get_brand_design_tokenspublicDesign tokens as DTCG JSON: color, type, spacing, motion.
  • get_brand_kitpublicThe render-ready kit: colors, fonts, logo, name, spacing.
  • get_brand_design_systempublicThe design system measured from the live site, each value with its confidence.
  • list_design_extraction_runspublicThe brand's design-extraction runs, newest first.
  • get_product_design_systempublicOne product page's design, as overrides of the brand's system.

Agencies work

Discover, activate, and read the deliverables an owned engagement produces.

  • list_brandsinternalThe brands this token can act on, each { slug, name }.
  • list_engagementsinternalYour engagements and their per-deliverable status.
  • activate_agency_packinternal · writeA write tool. Queues work or hands back a human-action URL; never a charge.
  • get_engagement_statusinternalPoll an engagement until each deliverable is ready.
  • get_deliverableinternalRead one rendered deliverable when it is ready.

Voice

Rewrite copy in a brand voice through the real Ghost voice-transform service.

  • list_voice_profilesinternalThe voice profiles your allowlisted brands are mapped to.
  • voice_transforminternalRewrite copy in a brand voice, with a verification report.

AI-accuracy audit

What the major AI engines say about a brand, graded claim by claim.

  • audit_brandinternalStart an audit by domain. Fire-and-poll; recent runs dedupe.
  • get_audit_statusinternalPoll a run: score, flagged claims, verdicts, sources.

Learning inbox

Hand a brand a document; the facts it mines wait for a human to approve them.

  • ingest_documentinternal · writeA write tool. Files pasted text into the inbox as proposals; nothing is canonical until approved.
  • get_ingest_runinternalPoll a mining run: progress, counts, and an honest failure reason.

Public tools (5) are what the no-login demo token lists; paid tiers unlock more. Internal tools ride owner-bound and operator-issued tokens; to anything below their audience they read as unknown methods.

Token lifecycle
  • Mint. From /account/tokens. The secret is shown exactly once and stored only as a hash.
  • Rotate. A 24-hour overlap by default (48h maximum): the old secret keeps working while you swap in the new one. A revoked token cannot be rotated back to life.
  • Revoke. Immediate, from the same panel.
  • Demo. 60 minutes, read-only, showcase brands only. It expires; nothing to clean up.
Tiers
  • Demo token · Free. No login. Read-only, showcase brands, 60-minute window.
  • Connected · $99/mo. Grounds your agents on your own brand. One brand, connected over MCP. Founding rate $69/mo, 30% off list and time-limited.
  • Brand · $449/mo. The full brand surface for your team. Founding rate $299/mo, a third off list and time-limited.
  • Agency · $1,499/mo. Adds the operator surface across every client brand you hold keys for.

Founding is the early rate: about a third off list, time-limited. Connected is $69/mo founding against $99 list; Brand is $299/mo founding against $449 list. No struck-through fake prices.

Audit and rate limits
  • 120 requests a minute per token. Over it, a 429 with Retry-After.
  • An audit row on every call. Free-text fields are redacted before hashing, so the stored trail cannot be dictionary-attacked back to your prompts.
  • Demo perimeter. 5 mints an hour per IP, 3 concurrently active per IP fail-closed, and a kill switch.

Three questions, straight.

Can my agent buy things?
No, by design. Two tools write, and neither can spend: one queues work and hands back a human-action URL (a checkout link or an intake form), the other files a document into your learning inbox for a person to approve. An agent can prepare a purchase; a person completes it.
What can it read?
The tools your tier and brand allowlist grant, checked live on every call. The public projection excludes competitive intel, pricing, and internal metadata.
What does it cost?
Connected is $99/mo, or $69/mo at the founding rate. Brand is $449/mo, or $299/mo founding. Agency is $1,499/mo. Founding is about a third off list and time-limited. The demo token is free and needs no login.
