Felt Cards — connector documentation

Felt mails real, handwritten-feel greeting cards. This connector lets you bring Felt into Claude (or ChatGPT): mention a card-worthy moment and it lands on your Felt list, ready to become a card Felt seals, stamps, and mails.

Connecting

In Claude → Settings → Connectors → Add custom connector, use this URL:

https://connect.feltapp.com

Claude opens a Felt sign-in page; sign in with your Felt email and password and approve. That's a one-time step — after it, "add this to Felt" just works. ChatGPT is supported too, via a GPT Action importing https://connect.feltapp.com/openapi.json.

What it can do

The connector exposes six tools, all scoped to your own Felt account:

Tool	Access	What it does
`save_moment`	writes	Saves a card-worthy moment to your Felt list — who it's for, the occasion, and roughly when. Felt reminds you when it's time to make and mail the card.
`list_moments`	reads	Lists the moments you've saved (open, already-carded, or all).
`create_list`	writes	Creates a new Felt list and can seed it with people by name. Returns a share link so each person can fill in their own mailing address.
`add_people_to_list`	writes	Adds people (by name) to one of your existing manual Felt lists.
`list_lists`	reads	Lists your Felt lists — name, how many people, and whether each is smart or manual.
`add_address_to_order`	writes	Adds a mailing address you supply to a card already waiting on one in Felt (for a person you've asked for an address). Felt verifies it and the card mails.

Billing — it never charges

This connector never charges you and never sends a card on its own. It only captures moments and organizes who they're for. Every card is something you review, finish, and pay for yourself in the Felt app. There are no financial-transaction tools.

Data, privacy & security

Owner-scoped. Every request acts only on the signed-in person's own Felt account — their moments, their lists, and contact names / addresses they add.
Standard OAuth 2.1 + PKCE. Access is granted by the user signing in to Felt; the connector receives a scoped access token, never the password to store. Users can disconnect at any time from Claude's connector settings, which revokes access.
What it accesses: the moments you save, your Felt lists and the names on them, and — only for add_address_to_order — a mailing address you provide for a card you're sending. It does not read anything else in your account.
No selling or sharing. Data is used only to fulfill your request within Felt. See Felt's Privacy & Security Policy.
Transport: all traffic is HTTPS/TLS.
