+title: New GraphQL Analytics API Explorer and MCP Server  
+description: Easily explore, build, and run GraphQL queries with two new tools  
+date: 2025-05-23T11:00:00Z  
+---
+
+We’ve launched two powerful new tools to make the [GraphQL Analytics API](https://developers.cloudflare.com/analytics/graphql-api/) more accessible:
+
+#### GraphQL API Explorer
+
+The new [GraphQL API Explorer](https://graphql.cloudflare.com/explorer) helps you build, test, and run queries directly in your browser. Features include:
+
+- In-browser schema documentation to browse available datasets and fields  
+- Interactive query editor with autocomplete and inline documentation  
+- A "Run in GraphQL API Explorer" button to execute example queries from our docs  
+- Seamless OAuth authentication — no manual setup required

+
+#### GraphQL Model Context Protocol (MCP) Server
+
+The new [GraphQL MCP server](https://github.com/cloudflare/mcp-server-cloudflare/tree/main/apps/graphql) helps you discover and generate useful queries for the GraphQL Analytics API. With the MCP server, you can:
+
+- Explore what data is available to query  
+- Generate and refine queries using natural language, with one-click links to run them in the API Explorer  
+- Build dashboards and visualizations from structured query outputs  
+
+Example prompts include:
+
+- “Show me HTTP traffic for the last 7 days for example.com”  
+- “What GraphQL node returns firewall events?”  
+- “Can you generate a link to the Cloudflare GraphQL API Explorer with a pre-populated query and variables?”
