Connect Brand Brain
to the assistant you already use.

One brand memory for every assistant. Claude, ChatGPT, Meta Muse, Claude Code and any agent that speaks MCP or HTTP can read your brand's confirmed identity, house rules, drafts and decisions, run the Brand Brain playbooks against it, and write back with your approval.

Endpoints

MCP server (Streamable HTTP): https://brain.fowl-ai.com/mcp
REST: https://brain.fowl-ai.com/api/v1
OpenAPI 3.1: https://brain.fowl-ai.com/api/v1/openapi.json
OAuth discovery: https://brain.fowl-ai.com/.well-known/oauth-authorization-server

Add it to your assistant

Claude (web, desktop, mobile): Customize, Connectors, Add custom connector, paste the MCP URL. Sign in when asked.
Claude Code: claude mcp add --transport http brandbrain https://brain.fowl-ai.com/mcp, then /mcp to sign in. Or with a key: claude mcp add --transport http brandbrain https://brain.fowl-ai.com/mcp --header "Authorization: Bearer bbk_…".
ChatGPT: Settings, Apps, Advanced settings, Developer mode, add the MCP URL with OAuth.
Meta Muse: create an API key in Settings, then ask Muse to connect to the MCP URL (or the OpenAPI document) with that key as a bearer token.
Scripts: send the API key as Authorization: Bearer or x-api-key to either endpoint.

Desktop apps

Claude Desktop and the ChatGPT desktop app use the same connection as the web. Add Brand Brain once in claude.ai or ChatGPT and it appears in the desktop app on the same account; sign-in opens in your browser. The brand card, proposal card and playbook picker render inside both desktop apps, in light and dark mode.

In Claude Desktop you can also add it directly: Settings, Connectors, Add custom connector, paste https://brain.fowl-ai.com/mcp.

What it feels like

whats_next greets you with where your brand stands, a brain score and the best next move, as a card with one-tap buttons.
find_playbook turns “I want to sell a template” into the right playbook, and says what it still needs from your brand.
review_output checks a draft before it goes out: house style, every price and figure traceable, no placeholders, no invented testimonials, a real link.
Proposed changes appear as a card with Apply and Reject.

Read tools

get_profile Which account is connected.
list_brands Brands on the account, with ids.
get_brand The whole brain: brief, sections, house rules, session state, decisions, proposals, outputs.
get_brand_section One section with its field keys and raw worksheet.
search_brand Text search across sections, outputs, decisions and rules.
list_outputs Saved drafts.
get_output One draft in full, paged.
get_playbook The playbook catalogue (no sign-in) or one playbook rendered with the brand brief.
whats_next Brain score, sections filled, and the best next moves with the question to ask.
find_playbook The right playbook for a request in plain words, with readiness (no sign-in needed).
review_output Automatic and checklist review of a saved draft.

Write tools

create_brand A new brand seeded with the 14 worksheets.
propose_brand_update A change to one section, as a proposal the person reviews (or applied when they already approved it).
resolve_brand_update Apply or reject a proposal.
save_output Save a draft: page, newsletter, post, sequence, PDF text, script.
log_decision Record a direction-setting choice.
log_lesson Capture a lesson; optionally promote it to a house rule.
set_session_state Where work stopped, so the next session resumes.

Free accounts get one brand, three saved drafts and the three starter playbooks; every other playbook appears in the catalogue as a locked title, and asking for one returns a pay prompt with the pricing link that the assistant can relay. Every change to a brand section is a proposal. The assistant applies it only when you approved that exact change in the conversation; otherwise it waits for you on the brand page. Publishing, sending and payments never happen through an assistant.

Playbooks (124)

Each playbook is also an MCP prompt. In Claude Code they appear as slash commands once connected.

Authentication

OAuth 2.1 with PKCE (S256) on this origin; clients identify with a Client ID Metadata Document or register dynamically at /oauth/register; public clients only. Scopes: brand:read, brand:write, offline_access. Personal API keys (prefix bbk_) work on both endpoints. An unauthenticated call to a brand tool answers 401 with a WWW-Authenticate challenge naming the protected-resource document, so assistants connect lazily.

Try a prompt

Connect my Brand Brain and show me the brief for my brand.
Using my brand's voice, draft next month's newsletter issue and save it as a draft.
Import my brand from my website and propose what should go in each section.
Run the website playbook for my brand and tell me what is still missing.
What did we decide about pricing? Search my brand.
Save where we stopped so I can pick this up in ChatGPT tomorrow.

Limits

MCP and REST: 300 requests a minute per address, 600 per API key. Tool results stay under 150k characters; long outputs are paged. Brand sections up to 200k characters, outputs up to 500k.

Data and privacy

Your brand data leaves only through a token or key you created, only for the scopes you saw. See the privacy policy and terms. Questions: [email protected].
