Coredash
Query real-user Core Web Vitals (LCP, INP, CLS) from your live site inside Claude Code or Cursor while you debug performance regressions.
Overview
Coredash is a MCP server for the Operate phase that lets agents query Real User Monitoring for Core Web Vitals (LCP, INP, CLS) from CoreDash production data.
What is this MCP server?
- Streamable HTTP MCP at app.coredash.app with Bearer API key or OAuth discovery
- Real User Monitoring focused on LCP, INP, and CLS from actual sessions
- Pairs with CoreDash dashboard at coredash.app for visitor-weighted trends
- Server schema version 1.0.1 with documented Authorization header format
- Designed for agents that need production perf context without opening analytics UIs manually
What problem does it solve?
Lab metrics and guesses do not tell you what real users feel when Core Web Vitals slip in production.
Who is it for?
Indie builders who already run CoreDash RUM on a live URL and want agent-assisted performance investigations.
Skip if: Greenfield sites with no RUM snippet, or teams that only need one-off Lighthouse runs in CI.
What do I get? / Deliverables
Your agent can pull field vitals context from CoreDash so you prioritize fixes against actual visitor impact.
- Agent-queryable LCP, INP, and CLS context from real visitors
- Faster production perf triage without switching to the CoreDash UI alone
Recommended MCP Servers
Journey fit
RUM answers how real visitors experience speed and interactivity after ship—canonical home is operating production, not one-off local builds. Field-data monitoring and vitals drill-down map directly to the monitoring subphase for ongoing site health.
How it compares
Production RUM MCP integration, not a local Lighthouse or build-time perf skill.
Common Questions / FAQ
Who is Coredash MCP for?
Solo and small-team builders who ship web apps or content sites and already use CoreDash to collect real-user Core Web Vitals.
When should I use Coredash MCP?
Use it in Operate when CLS, INP, or LCP issues appear in the wild and you need field data while debugging with your agent.
How do I add Coredash MCP to my agent?
Add the streamable-http remote https://app.coredash.app/api/mcp with Authorization Bearer cdk_YOUR_API_KEY from coredash.app/settings/api, or configure OAuth via WWW-Authenticate discovery per server.json.
