Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http coredash https://app.coredash.app/api/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "coredash": {
      "url": "https://app.coredash.app/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "coredash": {
      "type": "http",
      "url": "https://app.coredash.app/api/mcp",
      "headers": {

Your choice stays on this device in a cookie; no account needed.

Values you fill in

Authorization secret required HTTP header
Bearer token in the format 'Bearer cdk_YOUR_API_KEY'. Generate a key at https://coredash.app/settings/api. OAuth is also supported via WWW-Authenticate discovery.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Coredash safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

CoreDash MCP Server

Real User Monitoring for Core Web Vitals. Query LCP, INP, and CLS field data from real visitors through the Model Context Protocol.

The MCP server is hosted at https://app.coredash.app/api/mcp. This repo holds the public connector docs and registry manifest. You do not need to install or run a server. You connect your MCP client directly to the hosted endpoint.

What CoreDash is

CoreDash is a Real User Monitoring platform built around Core Web Vitals. It collects LCP, INP, and CLS from real visitors and lets you segment by page template, country, device, browser, OS, and 20 plus other dimensions. Data is stored in the EU. The product runs without consent banners. Paid plans start at $19 per month. More at coredash.app.

Tools exposed via MCP

Tool	Purpose
`get_metrics`	Current performance scores at p75. Filter and group by any dimension. Use for "what is" questions.
`get_timeseries`	Metric over time with an `improving`, `stable`, or `regressing` summary. Use for regressions and trends.
`get_histogram`	Distribution shape of a single metric across roughly 40 buckets. Use to see whether traffic is bimodal, long tailed, or evenly slow.

All three tools return rated buckets (good, improve, poor) matching the Core Web Vitals thresholds. Filter dimensions include device (d), country (cc), page path (ff), URL (u), browser, OS, and the LCP / INP / CLS attribution element selectors.

Authentication

The server supports two methods:

OAuth (recommended). Point your MCP client at the server URL and complete the browser sign-in when prompted — no API key required. The server follows the WWW-Authenticate discovery flow and publishes /.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource.
API key. Best for CI or headless use. Generate one at coredash.app/settings/api and pass it as Authorization: Bearer cdk_YOUR_API_KEY.

Anonymous calls succeed for initialize (so clients can introspect server capabilities) and fail for any tool call.

Connecting

Claude Code

Add the server, then authenticate in the browser:

claude mcp add --transport http coredash https://app.coredash.app/api/mcp

Run /mcp inside Claude Code, select coredash, and complete the OAuth sign-in.

To use an API key instead (e.g. in CI), pass it as a header:

claude mcp add --transport http coredash https://app.coredash.app/api/mcp \

--header "Authorization: Bearer cdk_YOUR_API_KEY"

Cursor

Add to ~/.cursor/mcp.json, then click Login on the server in Cursor's MCP settings to complete OAuth:

"mcpServers": { "coredash": { "url": "https://app.coredash.app/api/mcp" } } }

To use an API key instead, add a "headers" block with "Authorization": "Bearer cdk_YOUR_API_KEY".

VS Code

Add to .vscode/mcp.json in your workspace (or the user config via the MCP: Open User Configuration command). VS Code prompts you to sign in on first use:

"servers": { "coredash": { "type": "http", "url": "https://app.coredash.app/api/mcp" } } }

To use an API key instead, add a "headers" block with "Authorization": "Bearer cdk_YOUR_API_KEY".

Windsurf

Same JSON shape as Cursor, in the Windsurf MCP settings.

Any other MCP client

Point it at https://app.coredash.app/api/mcp with the streamable-http transport. Clients that support OAuth discover the flow via the WWW-Authenticate header; otherwise pass an Authorization: Bearer cdk_YOUR_API_KEY header.

Example queries

Why is LCP slow on mobile in Germany this week?

Has INP regressed on the product detail template in the last 24 hours? Show me the LCP distribution on /checkout/* in the US.

Registry listing

This server is published on the Official MCP Registry as io.github.corewebvitals/coredash. From there it propagates to PulseMCP, Smithery, Glama, and Windsurf.

The registry manifest is in server.json. To publish a new version, edit the file and run mcp-publisher publish.
