Handwrite.io

Handwrite.io creates and tracks physical handwritten card orders using selectable handwriting and stationery styles.

Verdict

Handwrite.io lets your team send physical handwritten cards from inside Switchy Projects. @mention it to create orders for thank-you notes, event invitations, or customer outreach — the AI drafts the message, picks a handwriting style and stationery design, then queues the card for printing and mailing. Marketing and customer success teams use it to automate personalized touches at scale without leaving the workspace. You'll need a Handwrite.io API key (test keys create orders without charging or shipping; live keys bill per card and trigger fulfillment). The MCP exposes four tools: sending cards, listing available handwriting styles and stationery, and checking order status.

Common use cases

  • Send thank-you cards after customer calls
  • Mail event invitations with custom messages
  • Automate birthday cards for VIP clients
  • Follow up on closed deals with handwritten notes
  • Send onboarding welcome cards to new hires

Setup

Setup guide

  1. 11. Sign up at Handwrite.io and generate an API key from your account dashboard (use a test key for experimentation or a live key for production orders). 2. In Switchy, open Settings and navigate to the Integrations tab. 3. Find Handwrite.io in the MCP directory and click Connect. 4. Paste your API key when prompted and save. 5. Open any Project and type '@Handwrite.io list handwriting styles' to confirm the connection works — you should see a list of available fonts with preview URLs. 6. To send a test card, ask '@Handwrite.io send a thank-you card to [name and address] in the Elegant style on Classic White stationery with the message [your text]' and verify the order appears in your Handwrite.io dashboard.

What teammates see: by default, memories from Handwrite.io are scoped to the Project (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

Example outputs

Illustrative - representative of the model's voice and quality, not literal recordings.

Prompt

@handwrite show me all available handwriting styles with preview links so I can pick one for our holiday cards

Output

Here are the handwriting styles available to your account: 1. **Casual Script** (ID: hs_casual_001) — relaxed, friendly cursive with slight right slant. Preview: [link] 2. **Formal Copperplate** (ID: hs_formal_003) — traditional business penmanship with consistent spacing. Preview: [link] 3. **Modern Print** (ID: hs_print_002) — clean block letters, highly legible. Preview: [link] Each style includes a sample image showing how your message will appear on the card. You'll need the style ID when creating an order.

Notes

This read-only call requires only API key auth and has no side effects. Handwriting styles are account-specific — custom styles uploaded by your team will appear here alongside public options. Preview URLs expire after 24 hours in some configurations.

Prompt

@handwrite send a thank-you card to Jamie Chen at 123 Market St, San Francisco CA 94103 using the Casual Script style, message: 'Thanks for the partnership this quarter—looking forward to what's next!'

Output

Order created successfully (Order ID: ord_live_abc123). **Recipient:** Jamie Chen, 123 Market St, San Francisco, CA 94103 **Style:** Casual Script **Message:** 'Thanks for the partnership this quarter—looking forward to what's next!' **Status:** Processing — card will be handwritten, inserted into envelope, and mailed within 1-2 business days. This is a **live order** and will be billed to your account. A proof image will be available once the card is written.

Notes

This example uses a live API key, so it creates a billable physical card order. With a test key, the order would be marked non-production and no card would ship. You must provide a valid postal address and select a handwriting style ID from the list-styles call. Rate limits apply to bulk sends.

Prompt

@handwrite I need to send personalized thank-you cards to our top 5 customers this month. Pull their names and addresses from the context above, pick an appropriate formal style, and draft a short message thanking them for their loyalty.

Output

I've identified 5 customers from the conversation and drafted a message: **Message:** 'Thank you for your continued trust in our work. We're grateful for your partnership and excited to support your goals in the year ahead.' **Recommended style:** Formal Copperplate (professional tone, matches the message). Ready to send? I can create 5 orders with this message to: - Alex Rivera, 456 Oak Ave, Austin TX - Jordan Lee, 789 Pine Rd, Seattle WA - Taylor Kim, 321 Elm St, Boston MA - Morgan Patel, 654 Maple Dr, Denver CO - Casey Wong, 987 Birch Ln, Portland OR Confirm and I'll submit the batch.

Notes

This synthesis example shows the MCP paired with AI reasoning to draft personalized outreach at scale. The AI composes the message and selects the style; you approve before the orders are created. Each card is a separate billable order, so batch sends can add up quickly — review the total before confirming.

Use-case deep-dives

Customer onboarding thank-you cards

When handwritten cards beat email for new B2B customers

A 6-person SaaS company closes 8-12 enterprise deals per quarter and wants each new customer to feel special during onboarding. The founder used to write cards by hand, but now delegates to the CS team using Handwrite.io's MCP. The team pulls new-deal data from their CRM, picks a handwriting style that matches the founder's signature, and queues cards in a shared Switchy workspace. The MCP's 4 tools cover the full loop: list styles, preview stationery, send cards, and check delivery status. This works because the volume is low and the per-card cost (around $3-5) is trivial compared to contract value. If you're sending more than 50 cards a month, budget becomes the constraint and you'll want tighter approval gates. For high-touch B2B onboarding under 20 cards per month, this MCP turns a manual founder task into a repeatable team ritual.

Event follow-up for conference leads

Handwritten follow-up at trade-show scale: when it pencils out

A 3-person sales team attends 4 trade shows per year and collects 40-60 qualified leads per event. They want to stand out in the post-show follow-up flood with handwritten cards, not generic email sequences. Using Handwrite.io's MCP in Switchy, they batch-create card orders from a spreadsheet of booth conversations, preview stationery to match the event theme, and track delivery status so they know when to follow up by phone. The MCP's Send Handwritten Cards tool handles bulk orders in one call, which matters when you're processing 50 addresses on the flight home. The math works if your average deal size is over $5k and you're targeting decision-makers who remember tactile gestures. Below that threshold or above 100 cards per event, the cost and logistics tilt toward email. For mid-volume, high-value outreach where differentiation matters, this MCP automates the logistics without losing the personal touch.

Holiday client appreciation campaigns

Seasonal card campaigns for agencies with 30-80 active clients

A 10-person creative agency sends holiday cards to 60 active clients every December. The account team used to order cards from a print shop, hand-address envelopes, and coordinate signatures—taking 12+ hours of billable time. Now they use Handwrite.io's MCP to automate everything except the message copy. They list available stationery in Switchy, pick a design that matches their brand, select a handwriting style that feels warm but professional, and send all 60 cards in one batch. The MCP's Get Order tool lets them confirm delivery before the holiday window closes. This scenario works because the card count is high enough to justify setup time but low enough that per-card cost stays under $300 total. If your client list is over 200, you'll hit budget friction and need to segment by tier. For agencies with 30-100 clients who want to show appreciation without manual labor, this MCP turns a December scramble into a 90-minute workflow.

Frequently asked

What does the Handwrite.io MCP do in Switchy?

It lets your AI agents send physical handwritten cards through Handwrite.io's service. Agents can browse available handwriting styles and stationery, create card orders for multiple recipients, and check order status. In test mode, it creates non-production records without sending physical cards; in live mode, orders are billable and ship to real addresses.

Do I need a live API key or can I test it first?

You can use either. Handwrite.io provides separate test and live API keys. Connect the test key in Switchy to experiment with card designs and order flows without billing or shipping anything. When you're ready to send real cards, swap in your live API key. The MCP works identically with both key types.

Can the MCP customize handwriting or only use preset styles?

It uses preset handwriting styles from Handwrite.io's library. The MCP can list all styles available to your account and select one when creating an order, but it can't generate custom handwriting on the fly. If you need a specific style, upload it to your Handwrite.io account first, then the MCP can reference it by ID.

Why use this instead of Handwrite.io's dashboard or API directly?

The MCP lets your AI agents send cards as part of automated workflows without you writing integration code. An agent can decide to send a thank-you card after a deal closes, pick an appropriate style, and create the order in one step. The dashboard requires manual work; the raw API requires you to build and maintain the integration yourself.

Who on the team should connect the Handwrite.io API key?

Whoever manages your Handwrite.io account and understands your card-sending budget. Live API keys create billable orders, so you want someone who can monitor spend and approve use cases. For testing, any team member can connect a test key without risk. The key itself doesn't expire unless you regenerate it in Handwrite.io.
