Overview

AI-generated overview

Haechy lets an assistant put a small app online for a team, with a web address, sign-in, saved data and backups.

What you can do
  • Create, deploy, check and share small apps built with the assistant
  • Provide a database and sign-in for colleagues on the deployed app
  • Store app secrets as environment variables that are never shown back
  • Request outside network access for an app, pending your approval
  • Run nightly backups and host apps in the US, EU, UK or Australia
When to use it
Use it when you build a small internal tool or app with an assistant and want it hosted for colleagues with sign-in and saved data, without setting up servers yourself.
Requirements
Remote MCP endpoint at mcp.haechy.com over streamable HTTP, with OAuth 2.1 (PKCE) sign-in; a Haechy account, which can be created during sign-in. Nothing runs locally. In Claude Code, deploying runs a tar and curl command from the project folder.
Before you install
Deploying uploads your project folder to Haechy, excluding node_modules, .git, .env, pycache and .venv; check for other sensitive files first. App secrets are stored by Haechy as environment variables. Outbound network access stays blocked until you approve each host in the Haechy console; the assistant can request but not approve it.

Installation

In SourceWeft

  1. Open Haechy in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.haechy%2Fhaechy/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Haechy plugin for Claude Code

Haechy puts the small apps you build with Claude online for your team: a database, sign-in for your colleagues, nightly backups, and outside connections that you approve one by one. Apps run in the US, the EU, the UK or Australia.

Install

/plugin marketplace add dantarakan/haechy-plugin/plugin install haechy@haechy

Then run /mcp, choose haechy and sign in. New accounts are created in the same window.

Prefer not to use a plugin? Add the connector directly:

claude mcp add --transport http --scope user haechy https://mcp.haechy.com/mcp/i/claude-directory

What this plugin does and sends

  • Adds one remote MCP server, https://mcp.haechy.com/mcp/i/claude-directory (OAuth 2.1 with PKCE). Nothing else is installed or run on your computer: no hooks, no commands, no local server.
  • Includes one skill (skills/haechy) with a technical build reference (skills/haechy/references/build-guide.md). When you ask Claude to put an app online, the skill has Claude call the Haechy connector's tools to create the app, deploy it, check the deploy and share it.
  • Uploads your project folder only when you ask to deploy. In Claude Code, the connector returns a single-use upload URL on a Haechy host, and Claude runs one command from the app's folder that packs it with tar (leaving out node_modules, .git, .env, __pycache__ and .venv) and sends it with curl to that URL. Outside Claude Code the files are passed to the connector directly.
  • Outside network access stays blocked for your app until you approve each host yourself in the Haechy console. Claude can ask for access and cannot approve it.
  • No credentials are stored in the plugin. API keys and passwords for your app are stored by Haechy as environment variables (set_env_vars) and their values are never shown back.
