For agents and developers

Let your agent design and send handwritten letters.

Your agent can use the handwriting fonts you make here: find the right one, draft a note, show you a preview, and mail it once you agree. Connect it through our MCP server, or call the REST API directly.

What an agent can do

MCP tool	Does	Cost
list_fonts	Your fonts: id, name, how many characters	free
get_font	One font: characters, alternates, settings, attribution	free
list_library	Library fonts with their attribution; their ids work for previews and sends	free
preview_letter	Render a letter or postcard as PDF, PNG or SVG	free
send_letter	Mail a handwritten letter	$1.00 or 100 credits
send_postcard	Mail a handwritten postcard	$1.65 or 165 credits
list_sends	Your sends, newest first, with status	free
get_send_status	Where a send is: queued, submitted, mailed…	free
get_credits	Balance and recent ledger	free

What keeps an agent in check

The MCP send tools instruct the agent to preview, show you the text, the address and the price, and wait for a clear yes. That is an instruction to the agent, not something our server can see or enforce. What the server does enforce: each API key can make at most 5 sends a day, it can only spend credits you already have, a card payment returns a checkout link you open yourself, and you can revoke a key at any time.

Credits work here too

Every send that is mailed earns 5 credits back. Making your first font in the studio earns 10 credits. See pricing.

Get an API key

Sign in with a passkey and make at least one font.
On your account page, create an API key and name it after the agent that will use it (“Claude Desktop”).
Copy the key straight away. It starts with hw_ and is shown once.
Revoke it on the same page whenever you like; the agent loses access immediately.

A key acts as you: it can read your fonts and spend your credits on sends, up to 5 sends a day per key. Give each agent its own.

MCP setup

The server runs on your machine over stdio (or as a small HTTP server) and forwards each call to the API with your key. It needs Node 20 or newer.

1. Build it

Terminal

git clone <this repo> handwritten && cd handwritten
npm install
npm run mcp:build

2a. Claude Code

Terminal

claude mcp add handwritten \
  --env HANDWRITTEN_API_KEY=hw_... \
  --env HANDWRITTEN_BASE_URL=https://your-handwritten-site \
  -- node /absolute/path/to/handwritten/mcp/dist/mcp/src/stdio.js

2b. Claude Desktop

claude_desktop_config.json

{
  "mcpServers": {
    "handwritten": {
      "command": "node",
      "args": [
        "/absolute/path/to/handwritten/mcp/dist/mcp/src/stdio.js"
      ],
      "env": {
        "HANDWRITTEN_API_KEY": "hw_...",
        "HANDWRITTEN_BASE_URL": "https://your-handwritten-site"
      }
    }
  }
}

Or over HTTP

Terminal

PORT=3333 HANDWRITTEN_BASE_URL=https://your-handwritten-site \
  npm run mcp:http

claude mcp add --transport http handwritten http://127.0.0.1:3333/mcp \
  --header "Authorization: Bearer hw_..."

The HTTP server holds no key; each client sends its own in the Authorization header.

Then ask: “Send my sister a postcard in my handwriting saying congratulations on the new flat.”

REST quickstart

Everything lives under /api/v1, speaks JSON, and takes your key as Authorization: Bearer. Stroke coordinates are em units from 0 to 1000 with y pointing down; money is in cents; times are ISO 8601 UTC.

Set up once

export HANDWRITTEN_BASE_URL=https://your-handwritten-site
export HANDWRITTEN_API_KEY=hw_...

Every error looks like this

{
  "error": {
    "code": "insufficient_credits",
    "message": "This postcard needs 165 credits."
  }
}

GET`/api/v1/fonts`

List the user's fonts (no stroke data).

POST`/api/v1/connect/android/approve`

The /connect/android page approves linking the Android app; answers the mailcraftfonts:// redirect.

The code in the redirect is single-use, lasts 5 minutes, is stored hashed and is bound to the PKCE challenge (S256).

Request

# Browser session only (passkey sign-in); API keys get 403. \
curl -s -X POST "$HANDWRITTEN_BASE_URL/api/v1/connect/android/approve" \
  -H "Content-Type: application/json" \

}

POST`/api/v1/connect/android/exchange`

The app trades its one-time code and PKCE verifier for its own API key.

No auth header: the code and verifier are the proof. A wrong verifier burns the code. The key can also change data consent (consent:write).

Request

curl -s -X POST "$HANDWRITTEN_BASE_URL/api/v1/connect/android/exchange" \
  -H "Content-Type: application/json" \
  -d '{"code":"one-time-code-from-the-redirect","codeVerifier":"dBjftJeZ4CVP-mB92K27uhbUJU1p1r_wW1gFWFOEjXk"}'
