Add Haechy to claude.ai

In claude.ai open Customize > Connectors, choose "+ Add" then "Add custom connector", name it Haechy, paste https://mcp.haechy.com/mcp and sign in. On Team and Enterprise plans an Owner adds it for the organization first, and each person then clicks "Connect".

Checked on 6 November 2026. Anthropic changes these menus from time to time.

On a Free, Pro or Max plan

  1. Go to Customize > Connectors.
  2. Choose "+ Add", then "Add custom connector".
  3. Enter the name Haechy and the address below, then choose "Continue".

https://mcp.haechy.com/mcp

  1. Review the authentication settings Claude detected and choose "Continue".
  2. Under "Authentication" pick "Sign in now".
  3. Under "OAuth client" keep "Use Claude's published identity (Recommended)". Haechy accepts it, so there is no client ID or secret to enter.
  4. Choose "Add".

Free plans can have one custom connector, so if you already use one, you may need to swap it.

Turn it on in a chat

Use the "+" button at the lower left of the chat box, choose "Connectors" and switch Haechy on. Then ask for what you want, for example "Put this app online with Haechy."

Team and Enterprise plans

Only an Owner or Primary Owner can add a custom connector for the organization. On Enterprise, a custom role with "Manage access to Libraries" works too. The Owner follows this path:

  1. Open Organization settings > Connectors and choose "Add".
  2. Hover "Custom", then pick "Web".
  3. Enter the name Haechy and the address above, then "Continue".
  4. Choose the authentication and OAuth client options as in the steps above, then "Add".

Members then open Customize > Connectors, find Haechy (it is usually labelled "Custom") and click "Connect" to sign in with their own account.

If you aren't the Owner, send yours this: "Please add a custom connector named Haechy with the address https://mcp.haechy.com/mcp. It lets us put apps built in Claude online."

What happens when you sign in

The sign-in window is Haechy's own console, not Claude. You enter your email and open the link Haechy sends (it works once, for 15 minutes). New users then enter a code texted to their mobile, which creates the account. The last page says Claude "wants to manage your Haechy apps" and lists what it can do; choose Allow and you are back in Claude. The quickstart covers what to ask next.

Phone and desktop

Connectors added on the web carry over to Claude Desktop. Claude for iOS and Android picks them up the next time you sign in on the phone.

Changing or removing the connector

To change a custom connector's details, remove it and add it again.

Using the command line instead? See Claude Code.
