Overview

AI-generated overview

Guardr is a hosted MCP server that lets an assistant check website health and list or inspect monitored sites.

What you can do
Check a website's health status with the check_site tool. List the sites being monitored with list_sites. Retrieve details for a specific site with get_site.
When to use it
Useful when you want an assistant to look up uptime or health status for sites you monitor in Guardr, or to review which sites are on your account, without leaving the chat.
Requirements
A remote endpoint at api.guardr.io using streamable HTTP. A Guardr API key, sent in the X-API-Key header, obtained from the Guardr dashboard under API Access. Network access is required.
Before you install
The API key in the X-API-Key header is a credential; keep it private and scope it as narrowly as the service allows. Site health data is sent to Guardr's hosted service.

Installation

In SourceWeft

  1. Open Guardr in the dashboard and add it to a workspace.
  2. Connect X-API-Key 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/io.guardr%2Fguardr/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

This server asks for a credential such as an API key, so SourceWeft could not read its tools without one and has not indexed them.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
