HTMLRadar for Claude, Cursor and any MCP client

HTMLRadar turns a web-page document into a link you control: only the people you choose can open it, you see who read it and which sections they stayed on, and it stays current on the same link.

This repository holds what you need to connect HTMLRadar to your agent: the Claude Code plugin, a skill that teaches your agent when to offer a tracked link, and the description of the connector for the MCP Registry. HTMLRadar itself is a hosted service at htmlradar.com.

Your agent publishes the page, checks who read it and updates it, while you decide who gets in. Readers need no account and nothing to install.

Install

Every client below connects to the same server, https://mcp.htmlradar.com/mcp. The first time your agent uses it, a browser page opens: you sign in to HTMLRadar (with Google, Microsoft or your e-mail address) and choose read-only or read-and-publish. There is no key to copy. You can end a connection at any time under Connected apps in Settings.

Claude Code

/plugin marketplace add htmlradar/htmlradar-mcp

/plugin install htmlradar@htmlradar

Then run /mcp, choose htmlradar and sign in.

Prefer not to use the plugin? This adds the same tools on their own:

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

Claude Desktop and claude.ai

Open Settings, then Connectors, then Add custom connector, and paste:

https://mcp.htmlradar.com/mcp

The first time Claude reaches for a tool, it shows a Connect card that opens the sign-in.

On Claude Team and Enterprise, an Owner adds the connector for the organization first; see htmlradar.com/mcp.

Cursor

Put this in ~/.cursor/mcp.json:

{

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

Then log in to HTMLRadar from Cursor's MCP settings. From the command line, cursor-agent mcp login htmlradar starts the same sign-in.

Any other MCP client

• Remote, with sign-in: if your client supports remote MCP servers with OAuth sign-in, point it at https://mcp.htmlradar.com/mcp. The server publishes standard OAuth discovery and accepts both client metadata documents and client registration.
• Package, with an API key: for a client without OAuth sign-in, create an API key at htmlradar.com/settings under API keys and run npx -y htmlradar-mcp (Node.js 20 or newer) with HTMLRADAR_API_KEY set in its environment. The package is htmlradar-mcp on npm. In Cursor, for example:

  {

"mcpServers": { "htmlradar": { "command": "npx", "args": ["-y", "htmlradar-mcp"], "env": { "HTMLRADAR_API_KEY": "${env:HTMLRADAR_API_KEY}" } } } }

The server is listed in the MCP Registry as com.htmlradar/share; server.json here is its description.

The 16 tools

Every tool is visible to every connection. A read-only connection can use the reading tools; the others need read-and-publish.

"Ask first" marks the tools that change what someone who already holds a link sees. The share-html skill in the plugin tells your agent to name the recipient and the document and get a yes before using them.

Plans

Free accounts can send two tracked links. Plans and prices are at htmlradar.com/pricing.
