About Code MCP

What is Code MCP: Seamless Integration & Lightning-Fast Coding?

Code MCP is a monorepo solution that bridges AI agents (e.g., Goose, Claude) with VS Code via the Model Context Protocol (MCP). It comprises a server and a VS Code extension, enabling AI to manipulate files, open projects, and interact with your editor in real time—without you lifting a finger (except for approving risky changes, of course).

How to Use Code MCP: Seamless Integration & Lightning-Fast Coding?

Step 1: Install the Server

npx code-mcp-server install

Step 2: Get the VS Code Extension

Visit the MCP Extension page and click "Install." VS Code will handle the rest.

Configure Your AI Assistant

For Goose Desktop: Set ID to "code-mcp" and point the Command to "npx code-mcp-server".
For Claude Desktop: Add the mcpServers block to your config file (see original docs for syntax).

Code MCP Features

Key Features of Code MCP: Seamless Integration & Lightning-Fast Coding?

AI-Powered Workflow Tools

create_diff: Propose code changes with a preview—because even AI needs a second pair of eyes.
open_file/project: Let AI open files or entire projects, like a digital intern who actually remembers where everything is.
check_extension_status: Debugging made easy (or at least faster). Just ask if VS Code is "listening."

Safety First

Modifications require your explicit approval—because we’ve all seen what happens when AI "helps" without supervision.

Use Cases of Code MCP: Seamless Integration & Lightning-Fast Coding?

Instant Code Reviews: "Goose, show me the diff for refactoring this legacy API—then I’ll decide if it’s genius or nonsense."
AI-Powered Project Setup: "Claude, open the ‘super-secret-project’ folder and list all recent files. Let’s dive in."
Automation Overlord: Turn repetitive tasks (e.g., updating config files) into a 2-second "approve & go" process.

Code MCP FAQ

FAQ from Code MCP: Seamless Integration & Lightning-Fast Coding?

Does this work with VS Code Insiders?: Yes! The extension is agnostic to VS Code versions—though we can’t promise it’ll fix your "extension host terminated" errors.
Can I use multiple MCP servers?: Absolutely. Configure each AI tool’s settings separately—like having a team of AI butlers, each with their own specialty.
Why the "Lightning-Fast" claim?: Because waiting for AI to type in your editor is like watching paint dry. MCP cuts out the middleman (literally).
What if the AI suggests something terrible?: That’s why we invented the "decline changes" button. Always keep your diff preview open—stay vigilant!
