CodeMirror-MCP Server: Enhancing AI Application Integration with MCP

Overview: What is CodeMirror-MCP Server?

The CodeMirror-MCP Server is an extension designed to implement the Model Context Protocol (MCP) for resource mentions and prompt commands within the CodeMirror editor framework. It provides developers a robust toolset to integrate AI applications more effectively by enabling seamless interaction between AI models, data sources, and user-generated content.

🔧 Core Features & MCP Capabilities

The CodeMirror-MCP Server offers several key features that enhance its integration capabilities:

Resource Completion: Autocomplete functionality for @resource mentions, allowing users to quickly access and reference relevant resources within their documents.
Resource Decorations: Visual styling and click handling for @resource mentions, providing a rich user experience with immediate access to resource details upon interaction.
Prompt Completion: Autocomplete support for /prompt commands, enabling quick invocation of specific AI functionalities or commands within the text editor.
Theme Support: Customizable styling options that can be tailored to match the overall design and branding requirements of the application.

⚙️ MCP Architecture & Protocol Implementation

The CodeMirror-MCP Server is built on top of MCP, a standardized protocol designed for universal communication between AI applications and tools. The protocol flow diagram illustrates how data flows between the AI application, the MCP client, the server, and the ultimate target resource or tool.

# Alternatively, use pnpm
pnpm add @marimo-team/codemirror-mcp @modelcontextprotocol/sdk

Peer Dependencies Overview

The CodeMirror-MCP Server requires the following peer dependencies:

@codemirror/view
@codemirror/state
@modelcontextprotocol/sdk

💡 Key Use Cases in AI Workflows

Code Completion and Debugging: Developers can quickly access documentation and code samples by referencing resources within their editor, improving coding efficiency.
Prompt-Based Interaction: Users can trigger specific commands or invoke AI prompts directly from the text editor, streamlining interaction with intelligent tools.

Example: Code Optimization Workflow

Imagine a developer working on complex algorithms where they need frequent references to external documentation and examples. With the CodeMirror-MCP Server, they can effortlessly add @resource mentions for relevant resources and use /prompt commands to generate optimized code snippets. This setup enhances their productivity and keeps them focused on coding.

Example: Prompt Execution Workflow

In an interactive environment where users might need to execute specific AI prompts, the CodeMirror-MCP Server allows for seamless integration. For instance, a user could insert /prompt analyze to trigger an analysis command in real-time, receiving results directly within the editor context.

🔌 Integration with MCP Clients

The CodeMirror-MCP Server seamlessly integrates with various MCP clients such as Claude Desktop, Continue, and Cursor. By enabling these clients to communicate effectively, developers can provide a richer user experience that leverages AI capabilities for enhanced productivity.

Configuration Example

Here's an example of how to configure the CodeMirror-MCP Server:

import { WebSocketClientTransport } from "@modelcontextprotocol/sdk/client/websocket.js";
import { mcpExtension, extractResources } from '@marimo-team/codemirror-mcp';
import { EditorView } from '@codemirror/view';

const transport = new WebSocketClientTransport(new URL('ws://localhost:8080'));

const view = new EditorView({
  extensions: [
    // ... other extensions

    mcpExtension({
      // Required options
      transport: transport,

      // Optional options
      logger: console,
      clientOptions: {
        name: 'your-client',
        version: '1.0.0'
      },
      onResourceClick: (resource) => {
        // Open resource
        // e.g. open in a tab, etc.
      },
    }),

    // Handle submit
    keymap.of([
      {
        key: 'Enter',
        run: () => {
          const resources = extractResources(view);
          const formattedResources = resources
            .map(
              ({ resource }) =>
                `${resource.uri} (${resource.type}): ${resource.description || resource.name}`
            )
            .join('\n');
          const prompt = `${view.state.doc.toString()}\n\nResources:\n${formattedResources}`;
          // ... submit prompt to AI server
          // const response = await generateText(prompt);
        },
      },
    ]),
  ],
  parent: document.querySelector('#editor'),
});
