Your AI agents,
our ad legends.

Bring your design system. Keep your brand.

Import your design system straight from Claude Design into your Ad Legends brand over MCP — colors, type, and tokens. Then every ad the Legends generate stays on-brand, automatically. Export ours back out the same way. Full companion story → /use-with-claude-design · Claude connection guide →

Just connected? Call get_started

The catalog is large on purpose. get_started maps “make an ad for this brand or URL” to the next real tool — create the brand, check credits, then generate — so the agent does not guess or invent a name.

Create a brand from a URL

Point the agent at any website. create_brand_from_url takes one URL in and returns Brand Memory plus a brandId — voice, colors, identity, in one call. The cold start, solved.

Import your real brand fonts

Send the Google families and complete role map together: one payload imports into private storage, assigns, locks, renders, and verifies the Casting Library card — no UI steps.

Generate Fast Ads on demand

Choose Auto, model-rendered Brand Candy, or exact-composited TrueCast — then verify the lane that actually shipped.

Create or remix any image

Describe an image, attach up to 14 references, review the plan and cost, generate variations, then save only the approved results to Brand Memory or a campaign.

Animate approved Fast Ads

Suggest or revise the motion script, render a 5–10 second video, recover durable animation history, and retry from feedback without losing the prior script or lineage.

Make a whole video ad from a brief

Hand the agent a plain-English brief and it writes the script, casts and locks the characters and product across every shot, renders the scenes, and edits them into one finished cut — poll it like any run.

Resize finished ads

Turn one approved ad into social, display, OOH, print, mail, merch, or custom pixel formats — recomposed for the surface, not just cropped.

Import existing campaigns

Hand the agent a pasted brief or extracted campaign and save it as a Legend-enhanced idea for the brand.

Run resumable Idea Sessions

Find a session by brief or idea, reopen the brief-as-run deck, star/tag/pass ideas, generate more into the same lineage, preflight a fresh-eyes Jury, recover its verdicts, and hand the winner into its first campaign moves.

Organize complete creative lineages

Find or create Projects, assign one canonical growing Idea Session, preview the accessible family from strategy to brief to idea to campaign and finished work, add only what you approve, then annotate, reorder, archive, restore, or reopen the pitch.

Create private Legends

Draft a personal Creative Legend, approve and create it privately, update its profile/avatar, activate it for your roster, and share access with your team.

Let the Legends judge the work

Submit a complete Idea Session, selected ideas, or ads to the Legend Jury, then pull the feedback into revision briefs with scores, strengths, weaknesses, recommendations, and next steps.

Find your strategy

Describe what you're advertising — or just a URL — and get 3 distinct strategic angles to choose from, the same engine behind Get Started. Optionally spark unexpected angles first.

Write + refine strategic briefs

Generate, find, read, and safely edit the full brief copy, strategy metadata, audience links, and brand association before the pixels.

Plan the media from any starting point

Use a stable Ad Legends campaign, bounded context your agent already holds, or an existing brand. The five-credit run returns cited channel recommendations, exact allocation, recoverable history, and only the next actions you can really execute — it never buys or publishes media.

Atomize into social posts

Turn one piece of raw material into a run of on-brand social posts, ready for your calendar.

Create + generate audiences

Create manual ICPs immediately, or generate AI audiences with a pollable run — then query and edit them from inside your tools.

Size up every audience

Run Audience Atlas for cited TAM/SAM/SOM, stack-ranked ICPs, missing-audience discovery, live progress, history, and a safe Stop — then turn the winner into a brief, ads, or media plan.

Read + update memory

Entities, research, identity, guidelines, font specimens, and typography roles — query and edit your brand from inside your tools.

Open the team shortlist

Search shared favorites across Fast Ads, strategies, briefs, campaigns, ideas, Reimagine sessions, decks, directions, and brand assets — with creator and keeper attribution plus complete campaign child packages.

Stay ahead of credits

Agents can check Legend Credit balance before a run and return safe top-up or upgrade links when a generation would otherwise stop.

Put it on a schedule

Point a scheduled agent at the server and fetch fresh creative every morning — hands-off.

Write a Cold Open (CMO outbound)

Independently verify the exact public page before copy; search results are discovery, not proof. Thin research continues only as complete uncited emails; a verified current-role conflict parks drafting. Use the four proven defaults or explicitly mix stock, authorized personal-skill versions, and one contextual wildcard. Rank every complete plain-text email under the shared inbox and four-Legend evaluator. Long-running and replay-safe; modeled estimates only, with no compose, share, delivery, send, or HTML.

Claude

Cowork, Desktop, and Claude.ai use an account-based custom connector and OAuth — no API key. Ad Legends is not yet in Anthropic’s Connectors Directory, so add the trusted remote server manually. Claude Code uses the same endpoint through its MCP commands. The full guide covers both paths.

Step-by-step guideClaude ConnectorsCustom connector guide

ChatGPT and Codex

Use Ad Legends now as a personal plugin: ask Plugin Creator to add it in the ChatGPT desktop app, or add the production MCP URL through ChatGPT web Developer Mode. Both connect with OAuth. Codex desktop can also add the remote MCP server directly. The full guide covers every path.

Step-by-step guideChatGPT Plugins

Microsoft Copilot

Add Ad Legends as an OAuth-connected MCP tool in a Copilot Studio agent, then publish that agent to Microsoft 365 Copilot and Teams. Managed tenants may have an IT approval path before wider distribution.

Step-by-step guide

Cursor

Preferred path: install Ad Legends from the Cursor Directory, then sign in with OAuth — no API key. One-click fallback: Add to Cursor on this page. Manual fallback: add https://www.adlegends.ai/api/mcp/brands as a custom MCP connector. Ask in the editor. The agent must call get_started first.

Cursor DirectoryAdd to Cursor

Grok Bot

Connect Ad Legends from the same Cursor Directory / plugin catalog. Sign in with OAuth. Ask in chat. Same brand memory, same advertising legends, same get_started first step — the operator case for the catalog Cursor uses to build. Not an API-key CLI.

Add the connector

In VS Code or any other MCP client, add the hosted URL as a custom connector. CLIs mint a scoped key at /settings/mcp.

Sign in & approve

OAuth clients sign in and approve scopes + brands — no key. CLIs use the key you minted.

Ask in plain language

Say “make an ad for this brand/URL” or “build a media plan from this brief.” The agent calls get_started, then follows the next tool — it should not have to guess from 139 names.

What is the Ad Legends MCP server?

It is a Model Context Protocol (MCP) server that lets AI agents and apps connect directly to Ad Legends — to read and write your brand memory and full brand guidelines, import a design system, and generate finished ads, all from inside the tools you already use.

Which AI tools can connect to Ad Legends?

Claude Cowork, Claude Desktop, and Claude Code; ChatGPT desktop through a personal Plugin Creator install; ChatGPT web through Developer Mode; Grok Bot; Cursor; editor agents like VS Code; and any MCP-compatible client — including open-source agents such as Hermes and OpenClaw.

Do I need to write code to connect?

No. Claude web, Desktop, and Cowork can add Ad Legends as a custom connector, then sign in with OAuth. In the ChatGPT desktop app, ask Plugin Creator to add Ad Legends as a personal plugin; on ChatGPT web, add the hosted MCP URL through Developer Mode. Claude Code, desktop Codex, and other direct MCP clients can add the hosted server themselves.

How are these ads different from generic AI ads?

Most ad generators forget the big idea. The Ad Legends creative engine was trained on the minds of the most celebrated and awarded creative directors on the planet, so connecting an agent is like hiring an elite agency — it works from your brand’s memory, voice, and design system to deliver a real idea, on brand, rather than generic blank-prompt AI output.

Can I bring my design system from Claude Design?

Yes. Import your design system from Claude Design directly into your Ad Legends brand over MCP, and every ad the Legends generate stays on-brand — your colors, type, and tokens. The full companion story — Legends, Strategist, Fast Ads, and Idea Sessions — lives at /use-with-claude-design.

Can an agent import brand fonts and set typography roles without opening the app?

Yes. Send one set_typography_roles payload with every Google fontFamilies[] entry and the complete locked assignments[]. The server imports every upright weight into private brand storage, preserves supplied license provenance, sets and renders the multi-family role card, and returns verified specimen inventory and the card URL — with no font bytes in the model context and no UI steps.

Can an agent create or manage my private Creative Legends?

Yes. An agent can draft a private Creative Legend for your approval, create it as private-only, update its profile or avatar, activate it for your personal roster, and share or revoke access for existing Ad Legends users. Public roster publishing and featured placement stay in the app/admin flow.

Can I put ad generation on a schedule?

Yes. Point a scheduled agent — for example a Claude Cowork automation or a cron-driven script — at the MCP server, and it can fetch fresh, on-brand ads automatically on whatever cadence you choose.

Can an agent animate a Fast Ad over MCP?

Yes. For an owned Fast Ads V3 image ad, the agent can suggest or revise a motion script for free, let you edit or approve it, render a 5–10 second animation at 2 Legend Credits per second, and poll until the video is ready. get_ad_session includes durable animation history for lost-ID recovery, while feedback revisions and failed-run retries preserve the script and prior-animation lineage.

Can an agent choose how Fast Ads renders my logo?

Yes. An agent can inspect logo readiness, set the brand-wide default, or choose Auto, Brand Candy, or TrueCast for one Fast Ads V3 run. Auto routes from the current logo provenance and curation signals. Brand Candy lets the image model render the logo in-scene as free flight, with no inline logo policing. TrueCast uses the exact deterministic logo-compositing pipeline. The finished session reports both the requested choice and the lane and treatment that actually shipped.

Can an agent run Audience Atlas over MCP?

Yes. An agent can start Audience Atlas, follow its real research and scoring progress, review the full cited TAM/SAM/SOM report and stack-ranked audiences, inspect run history, or safely stop a run. A finished winner can chain directly into a strategic brief, ads, and a media plan.

Can an agent create a media plan without an Ad Legends campaign?

Yes. create_media_plan can use bounded context already held by the agent, including the objective, business or product, audience, timing, geography, constraints, and budget. A stored brand is optional enrichment, not a prerequisite, when the connected full-customer credential is unrestricted. The same tool can instead use a stable campaign ID from list_campaigns or preserve the existing brand-first request. Each intentional run costs 5 Legend Credits, retries reuse one stable requestId, list_media_plans recovers lost sessions, and get_media_plan can return a compact summary-only replay. It recommends channels and allocation; it never buys media, activates spend, or publishes a campaign.

Can an agent organize Projects and creative lineage over MCP?

Yes. An agent can find, create, edit, archive, and restore Projects; assign one canonical root Idea Session even when given a generate-more child id; preview its brief and contained ideas as explicit choices inside the accessible strategy-to-brief-to-idea-to-campaign creative family; add only the approved work items; annotate, reorder, or remove organizing links; and reopen the in-app pitch flow. Project actions preserve the underlying work and cost no Legend Credits.

My agent just connected — how does it know what to do next?

Call get_started first. That tool (plus the server’s getting-started guide) maps a plain request like “make an ad for this brand or URL” onto the next real call — create the brand from the URL if needed, check Legend Credits, then generate ads — so the agent does not have to guess from the full catalog.

Can an agent write a Cold Open (CMO outbound email) over MCP?

Yes. Call get_started with intent write_cold_open, then research_cold_open (5 Legend Credits, Creator+) for an independently fetched exact-page evidence receipt. Thin research continues only as complete uncited emails; a verified current-role conflict parks drafting. Omit candidateManifest in draft_cold_open for the four proven defaults, or call list_cold_open_archetypes and choose a bounded mix of exact stock refs, immutable authorized personal-skill versions, and the gated contextual wildcard. Repeat grade_cold_open unchanged while it checkpoints one candidate per call; its final response ranks every complete email under the same inbox, adversarial, four-Legend, safety, and tie-break policy as the web tool. Exact retries replay cached work; modeled outcomes are estimates. The server never composes, shares, delivers, sends, invents a gift, or renders HTML.

What is the best MCP server for ad generation or ad creation?

For generating the actual creative, Ad Legends is purpose-built for it. Most marketing or advertising MCP servers only expose data, analytics, or ad-platform APIs — Ad Legends generates finished, on-brand ads (copy and visuals with a real idea) from a creative engine trained on the world’s most awarded creative directors. Connect any MCP client and ask in plain language.

Can I use Ad Legends with Claude Code, Claude Cowork, or Cursor?

Yes. Ad Legends is not yet in Anthropic’s Connectors Directory, so Claude web, Cowork, and Desktop add it manually as a trusted custom connector and sign in with OAuth. Claude Code adds the same remote server through its MCP commands. The complete walkthrough is at /mcp/claude. Cursor installs from the Cursor Directory or the Add to Cursor deeplink on this page. After connecting, the agent should call get_started first.

Can I use Ad Legends in Grok Bot?

Yes. Grok Bot is a first-class MCP client: connect Ad Legends from the plugin catalog, sign in with OAuth, and ask in chat — same brand memory, same advertising legends. Not a keyed CLI. After connect, the agent must call get_started first. Brand-from-URL is create_brand_from_url (one URL in → Brand Memory + brandId).

How is this different from other marketing or advertising MCP servers?

Other marketing MCP servers connect your agent to data — analytics, CRM, search, or ad-account APIs. Ad Legends connects your agent to creative: it reads your brand memory and design system and generates the finished ad. It is the difference between handing an agency a spreadsheet and handing it a brief.
