Generate a brand persona, callable

Builds the persona of a brand: the character it shows when it writes. Returns an archetype, voice traits, tone sliders, say and do-not-say lists, and a sample caption in that voice.

Most tools that answer to the word "persona" build a BUYER persona, a portrait of the customer being sold to. This builds the persona of the brand doing the talking, which is the thing that actually decides how the writing sounds.

There is a page for people too: the brand persona tool runs the same engine in a browser, free and without an account.

Inputs and bounds

These bounds are the ones the server enforces. A request outside them is refused with a message naming the field.
Field	What it is	Required	Length
brand	Your brand or your name	required	2 to 80
offer	What do you do?	required	12 to 240
audience	Who is it for?	required	6 to 200
tone	How do you want to sound?	required	3 to 160
avoid	What do you never want to sound like?	optional	up to 160

What comes back

archetype - one of twelve, with the line that explains the choice
traits - the adjectives the voice actually holds
sliders - formal/casual, measured/energetic, cool/warm, serious/playful
say and doNotSay - the vocabulary to hold and the vocabulary to refuse
sampleCaption - a caption written in the resulting voice, so the profile is testable rather than asserted

Where the data goes

The brief (brand, offer, audience, tone) is sent to the model provider. Nothing is stored and no request body is logged.

What it will not do

Not a buyer persona and not market research. It describes how a brand should sound, not who will buy from it, and it is grounded in what you type rather than in any data about your market.

Calling it

The server speaks MCP over JSON-RPC 2.0 at https://repic.site/api/free-tools/mcp. There is no key and no account. Calls share one per-IP daily budget with the free web tools, so an agent gets the same allowance a person does.

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "generate_brand_persona",
    "arguments": {
      "brand": "Marlow Coaching",
      "offer": "Career coaching for engineers moving into their first leadership role",
      "audience": "Senior engineers becoming managers",
      "tone": "Warm, plain, straightforward",
      "avoid": "Corporate, salesy"
    }
  }
}

Call tools/list first for every capability and its schema. The result carries both a readable content block and a lossless structuredContent object, so nothing has to be parsed out of prose.

The other skills

Brand voice

Measures how someone already writes and returns a reusable voice profile: tone sliders, traits, and concrete rewrite rules with a before and after.

Brand kit

Produces a starter kit: a palette with contrast-checked pairings, a type pairing, voice, values and a mission line.

Brand consistency

Scores two or more recent posts for drift against each other and against a stated palette and voice, and returns per-check findings with specific fixes.

Social bio

Writes bio variants that fit the platform character limit, with the name field and the call to action handled separately.

Carousel outline

Turns a topic into a slide-by-slide carousel outline: a hook, one idea per middle slide, a specific ask, and review notes saying what is still weak.
