Use Checkslip with AI assistants (MCP)

Claude Code

Run this in your terminal.

claude mcp add --transport http --scope user \
  checkslip https://mcp.checkslip.com/mcp

Sign in: In Claude Code, type /mcp, choose checkslip, then follow the steps in your browser.

--scope user makes it work in every project; without it, only in the current one.

Claude

1. Open Customize → Connectors, choose + Add, then Add custom connector.
2. Name it checkslip, paste the URL and choose Continue.
3. Under Authentication, choose Sign in now, then Add.

Sign in: With Sign in now, the sign-in page opens in your browser.

Works in claude.ai and Claude Desktop. On Team or Enterprise, an owner adds it under Organization settings → Connectors, then members choose Connect.

ChatGPT

1. Open chatgpt.com/plugins, choose the plus button, then Add custom MCP server.
2. Name it checkslip, paste the URL under Server URL and choose OAuth for authentication.
3. Choose I understand and want to continue, then Create as a plugin, and install the plugin.

Sign in: ChatGPT opens the sign-in page while it installs. In a chat, type @ and choose checkslip.

In a Business or Enterprise workspace, an admin has to allow Create plugins with MCPs first.

Cursor

Add to Cursor

Choose the button above, then Install in Cursor. Or put this in ~/.cursor/mcp.json.

{
  "mcpServers": {
    "checkslip": {
      "url": "https://mcp.checkslip.com/mcp"
    }
  }
}

Sign in: When Cursor says it needs sign-in, choose that prompt and carry on in your browser.

GitHub Copilot in VS Code

Add to VS CodeAdd to VS Code Insiders

Choose a button above, then Install on the page VS Code opens. Or open the Command Palette, run MCP: Add Server → HTTP, paste the URL and name it checkslip.

{
  "servers": {
    "checkslip": {
      "type": "http",
      "url": "https://mcp.checkslip.com/mcp"
    }
  }
}

Sign in: The first time it connects, your browser opens the sign-in page on its own.

Codex

Run this in your terminal.

codex mcp add checkslip --url https://mcp.checkslip.com/mcp
codex mcp login checkslip

[mcp_servers.checkslip]
url = "https://mcp.checkslip.com/mcp"

Sign in: codex mcp login checkslip opens your browser to sign in.

Codex CLI, the Codex IDE extension and the ChatGPT desktop app share ~/.codex/config.toml. In the extension and the app, choose Authenticate in the MCP servers list.

Gemini CLI

Run this in your terminal.

gemini mcp add --transport http --scope user \
  checkslip https://mcp.checkslip.com/mcp

{
  "mcpServers": {
    "checkslip": {
      "httpUrl": "https://mcp.checkslip.com/mcp"
    }
  }
}

Sign in: The first time it connects, Gemini CLI opens your browser to sign in. To sign in again, type /mcp auth checkslip.

In ~/.gemini/settings.json, use httpUrl (url means the older SSE transport).

Devin Desktop (Windsurf)

Put this in ~/.config/devin/mcp_config.json (Windows: %APPDATA%\devin\mcp_config.json). Customize → MCPs opens the file.

{
  "mcpServers": {
    "checkslip": {
      "url": "https://mcp.checkslip.com/mcp"
    }
  }
}

Sign in: The first time it connects, your browser opens to sign in. If it shows Needs authentication, choose Authenticate.

Other tools

If your tool connects by URL (Streamable HTTP) and can sign in with OAuth, put this in its MCP settings.

{
  "mcpServers": {
    "checkslip": {
      "url": "https://mcp.checkslip.com/mcp"
    }
  }
}

If the tool only runs local servers (STDIO), put mcp-remote in between. It opens the sign-in page in your browser itself, and needs Node.js on your computer.

{
  "mcpServers": {
    "checkslip": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.checkslip.com/mcp"
      ]
    }
  }
}
