Announcing the Vibe Coding Server (Optimized by Tadata) + CopilotKit MCP Client

Making coding copilots actually useful

We’re excited to share a major update in CopilotKit’s MCP ecosystem: We’ve launched the Vibe Coding Server, a new MCP server built with Tadata, designed to make coding copilots code reliably with CopilotKit.

Alongside it, we refreshed the Open MCP Client, so you can plug copilots into MCP servers directly inside your app. Together, they give you both:

A client bridge (frontend ↔ MCP servers)
A coding context source (CopilotKit docs + examples on tap)

Why Vibe Coding Server?

Most coding copilots fail when they don’t have the right context. They hallucinate APIs, miss integrations, or burn tokens on irrelevant docs.

The Vibe Coding Server fixes that:

Structured access to official CopilotKit docs + real code examples
Auto-fetches only relevant snippets (no page dumps → fewer tokens, faster)
Removes boilerplate tagging in every prompt — copilots always have context
Tested to deliver 66% faster integrations and fewer retries

So now when you ask Cursor or Claude Code:

“Build a CopilotKit UI integrated with my backend.”

→ The Vibe Coding Server streams the right snippets.
→ The copilot produces working code on the first try.

That’s what we call vibecodability.

The Open MCP Client (Refreshed)

The client makes this loop complete. We rebuilt our MCP Client into a full toolkit for agent-ready frontends:

Tool discovery at runtime
Native actions (LLMs call MCP tools alongside frontend/backend actions)
Live context streaming into conversations
UI integration with 'McpToolCall'

Any CopilotKit app can now connect directly to MCP servers without glue code.

Why This Matters

MCP has become the standard for connecting LLMs to external tools (Claude Desktop, Cursor, etc.). But until now, copilots lacked:

A reliable client layer for apps
A reliable context server for coding

CopilotKit now ships both.

Getting Started

It’s now easier than ever to spin up a working CopilotKit app with MCP support:

npx create-copilotkit-mcp-app

Preconfigured hooks + UI

Built-in integrations (LangChain, Composio, more)
