Introducing the Coni Introspection Agent & MCP Server

Imagine sitting in your REPL, writing code, and suddenly forgetting how a standard library function works. Or maybe you need a quick algorithmic implementation, but you don’t want to switch context to a browser or a separate AI chat window.

What if your programming language itself could introspect its own codebase, write code for you, and evaluate it live in your REPL memory?

Today, we’re thrilled to introduce the Coni Introspection Agent—a natively integrated, tool-calling LLM agent built directly into the Coni language ecosystem. And because we know developers love their modern IDEs, we’ve also packaged it with a native Model Context Protocol (MCP) server.

Building a Zero-Dependency MCP Client & Server Natively in Coni

The Model Context Protocol (MCP) is rapidly becoming the gold standard for connecting Large Language Models to external tools and data sources. Historically, if you wanted to build an MCP client or server, you needed to reach for heavy, bloated SDKs in Node.js or Python, dealing with complex asynchronous state and dependency hell.

We thought: What if we could do it entirely natively in Coni?

In this post, we’re going to walk through how we brought a complete, zero-dependency MCP Client and Server directly into the Coni standard library (mcp.coni). It’s fast, highly concurrent, and ridiculously easy to use.
