Overview

AI-generated overview

Zetlyn is a remote MCP server that lets an assistant watch a spot on a web page, such as a price, stock level or version, or a whole page, and report when it…

What you can do
  • Set up watches on a specific element or value within a web page, such as a price, stock status or version number.
  • Watch an entire page for changes rather than a single element.
  • Receive notifications when a watched value or page changes.
When to use it
Useful when you want an assistant to keep an eye on a page that matters to you, like a product price, availability, or a software version, and tell you when it moves instead of checking manually.
Requirements
A remote MCP endpoint reached over streamable HTTP; OAuth sign-in is required. No environment variables or headers are declared.
Before you install
Access is tied to an OAuth account, so the assistant acts on your Zetlyn account. Watches read third-party web pages, and the pages you choose to monitor are shared with the service. No tool list is published, so confirm what it can change or notify before relying on it.

Installation

In SourceWeft

  1. Open Zetlyn 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.zetlyn%2Fzetlyn/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.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
