The 6 best MCP servers of 2025 that changed how I approach AI coding. From pulling live documentation into Claude Code and Cursor AI, to managing databases with natural language—these tools transformed my entire development workflow. Here's what actually worked.

Context7 pulls up-to-date, version-specific documentation and code examples directly into your AI coding agent. Instead of dealing with outdated information or dependency mismatches, your agent gets a curated knowledge base for any library. It uses a vector database with semantic search to retrieve exactly what's relevant, unlike basic web search that returns unstructured results.

Google recently launched fully managed MCP servers for their cloud services. The Google Maps MCP enables location-based grounding with accurate data, BigQuery MCP lets agents interpret enterprise data without exposing sensitive information in context, and the Compute and Kubernetes MCPs handle cloud infrastructure and container operations. These are remote servers, not open source, but Google also maintains open-source MCPs for Workspace, Firebase, Analytics, and Flutter.

Docker MCP solves one of the biggest problems with running multiple tools: context bloat. Instead of loading hundreds of tools into your context window, Docker exposes just two tools that dynamically access whatever you need. Everything runs sandboxed, and you can connect to Docker's catalog of verified servers. It also supports Code Mode, which lets agents create JavaScript-enabled tools that call other MCP tools on the fly.

Shadcn Registry MCP is my go-to for UI components. It lets you install fully customizable components directly through your agent, with proper dependency handling. You can also connect additional registries like Aceternity UI and Magic UI by adding a few lines to your components.json file.

Notion MCP has been essential for managing our YouTube channel. It handles searching, creating, updating, and organizing pages across your workspace. I use it daily to track content states, manage team tasks, and refine ideas in our pipeline. If you use Obsidian instead, there's an equivalent MCP with the same capabilities.

Supabase MCP handles database schema management, SQL operations, and project configuration through natural language. Since we use Supabase for most of our smaller project backends, this eliminated the need to manually write queries or manage configurations. Your agent can set up entire environments from scratch just through prompting.
