Context7 MCP: update Astro project with best practices

---

🧠 Overview

The Context7 MCP Server lets Warp fetch live documentation from across the web.

In the example, the agent updates an older Astro project to align with the latest version (Astro 5).

---

1. Add the Context7 server

   • Open Warp’s MCP Panel via the Command Palette.
   • Add the Context7 JSON config and click Save.

   {
     "Context7": {
       "command": "npx",
       "args": [
         "-y",
         "@upstash/context7-mcp"
       ],
       "env": {},
       "working_directory": null
     }
   }

   • This enables the endpoint getLibraryDocs, which retrieves live documentation directly from the official sources.

2. Run the update prompt

   The developer issues this prompt:

   Create a new git branch called update and in that branch update this Astro project to follow all the latest best practices based on all Astro and developer documentation.

3. Review the automatic code changes

   The transcript shows that Warp automatically:

   • Updates Tailwind import syntax
   • Improves TypeScript configuration
   • Optimizes build settings
   • Enhances accessibility rules

   These edits happen across multiple files — without manually searching docs or changelogs.

4. Best use cases

   • Migrating old Astro, React, or Vue projects
   • Refreshing codebases to reflect recent standards
   • Saving time otherwise spent reading version notes
