   https://simple-host.app/mcpCopy
4. A sign-in window opens. Choose Continue with Google, or enter your email and the 6-digit code we send, then choose Allow.

2. Open ChatGPT Plugins.
3. Click Add, then choose Upload plugin archive, and choose the ZIP file.
4. When the sign-in window opens, choose Continue with Google, or enter your email and the 6-digit code we send, then choose Allow.

In a chat, pick Simple Host from the + menu, or just ask.

Simple Host 1.0.1 has been resubmitted to the ChatGPT app directory and is in review. Once it is approved, you will be able to add it from there.

Install the Simple Host plugin

One step: it adds the connector and the skills together, so Claude follows Simple Host's own instructions.

1. Open Claude, then Customize, then Plugins, then Discover.
2. Search for Simple Host, select it, then choose Add.

Connector only

1. Open Claude, then Settings, then Connectors, then Browse connectors.
2. Search for Simple Host, choose Connect, sign in, then choose Allow.

Both work on web, desktop, and phone.

On a network that blocks the directory, add it as a custom connector instead: name it Simple Host, paste this address:

1. Go to grok.com/connectors, choose New Connector, then Custom.
2. Name it Simple Host, paste this address into Server URL, and click Add Connector:
   https://simple-host.app/mcpCopy
3. Sign in once in the window that opens.

1. In VS Code, open the Command Palette and run MCP: Add Server, then choose HTTP.
2. Paste this address and name it simple-host:
   https://simple-host.app/mcpCopy
3. Sign in once in the window that opens, then ask Copilot Chat for a site.

1. In Muse, open Settings, then Connectors, then Add custom connector.
2. Paste this address as the MCP URL:
   https://simple-host.app/mcpCopy
3. Muse asks for a Client ID. Type this, not your email:
   meta-museCopy
4. Sign in once in the window that opens, then choose Allow.

1. On a computer, open gemini.google.com, then Settings, then Connected Apps.
2. Under Custom apps, choose Add a custom app, paste this address, and choose Next:
   https://simple-host.app/mcpCopy
3. Sign in once in the window that opens, then choose Allow.

Google offers custom apps to people 18 and over in the US, signed in with a personal account, with Keep Activity on. Once added, it works in the phone app too.

1. Open Connectors, choose Add Connector, then the Custom MCP Connector tab.

   https://simple-host.app/mcpCopy
3. Sign in once in the window that opens, then choose Allow.

On a team plan, an admin adds it first.

1. Text or tell Instinct: Set up Simple Host for me using https://simple-host.app/install.html
2. It reads this page and asks for your email. Reply with it.
3. We email you a 6-digit code. Send that back and it signs you in.

No connector window to open; it signs in with the same emailed code a coding agent uses in a terminal.

1. Run this in your terminal. It adds the connector and the skills:
   claude plugin marketplace add vineetu/simple-host && claude plugin install simple-host@simple-hostCopy
2. In Claude Code, type /mcp, choose simple-host, then Authenticate.
3. Sign in once in the window that opens, then choose Allow.

1. Run this in your terminal. It adds the skills and the connector:
   npx skills add vineetu/simple-host -g -a codex -y && codex mcp add simple-host --url https://simple-host.app/mcpCopy
2. Sign in once in the window that opens, then choose Allow.
3. Start Codex and ask for a site.

1. Run this on the computer where OpenClaw runs. It adds the skills and the connector:
   npx skills add vineetu/simple-host -g -a openclaw -y && openclaw mcp add simple-host --url https://simple-host.app/mcp --transport streamable-http --auth oauth && openclaw mcp login simple-hostCopy
2. Open the link it prints, sign in, then choose Allow.
3. Ask OpenClaw for a site, from any chat you use it in.

If OpenClaw runs on another computer, the browser ends on a page that does not load. Copy the code after code= in its address and run openclaw mcp login simple-host --code followed by the code.

1. Run this on the computer where Hermes runs. It adds the skills and the connector:
   npx skills add vineetu/simple-host -g -a hermes-agent -y && hermes mcp add simple-host --url https://simple-host.app/mcp --auth oauth --connect-timeout 300Copy
2. Open the link it prints, sign in, then choose Allow. When Hermes asks to enable the tools, press Enter.
3. Ask Hermes for a site, from any chat you use it in.

If Hermes runs on another computer, the browser ends on a page that does not load. Paste that page's address into Hermes when it asks.

1. Run this in your terminal and pick your agent:
   npx skills add vineetu/simple-hostCopy
2. In your agent's MCP settings, add a remote HTTP server named simple-host with this address:
   https://simple-host.app/mcpCopy
3. Sign in once in the window that opens, then choose Allow.

Your agent needs to support MCP sign-in (OAuth). Other ways to install
