+### VS Code MCP Servers (Optional)
+
+This repository includes `.vscode/mcp.json` which configures
+[MCP servers](https://code.visualstudio.com/docs/copilot/chat/mcp-servers) for
+AI-assisted development with GitHub Copilot. These are **optional** — everything
+works without them.
+
+| Requirement | What it provides | Install |
+|-------------|-----------------|---------|
+| Go 1.24+ with `gopls` | Go workspace tools (diagnostics, search, references) | VS Code Go extension installs `gopls` automatically |
+| Node.js 18+ with `npx` | GitHub, fetch, context7, sequential-thinking, memory servers | [nodejs.org](https://nodejs.org/) |
+| GitHub PAT (optional) | GitHub MCP server authentication | [Creating a PAT](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens) |
+
+If a server's prerequisites are not met, VS Code will skip that server with no
+impact on normal development.

 ## Production Build (Earthly)
 
 For reproducible production builds with automatic version injection.
