UBOS Asset Marketplace: TypeScript Definition Finder MCP Server - Empowering AI Code Editors

In the rapidly evolving landscape of AI-assisted software development, the ability for AI code editors to seamlessly understand and navigate complex codebases is paramount. UBOS is committed to providing developers with cutting-edge tools to enhance their productivity and code quality. As part of the UBOS Asset Marketplace, we proudly present the TypeScript Definition Finder MCP (Model Context Protocol) Server, a powerful solution meticulously crafted to empower AI code editors in pinpointing TypeScript symbol definitions within your projects.

What is MCP and Why It Matters

Before diving into the specifics of the TypeScript Definition Finder MCP Server, it’s essential to understand the significance of the Model Context Protocol (MCP). MCP is an open protocol that standardizes how applications provide context to Large Language Models (LLMs). In essence, an MCP server acts as a bridge, allowing AI models to access and interact with external data sources and tools. This integration is crucial for enabling AI code editors to deliver precise and context-aware assistance.

Use Cases

The TypeScript Definition Finder MCP Server addresses several critical use cases that significantly enhance the development workflow:

1. Effortless Symbol Definition Lookup: Developers often grapple with locating the original definitions of imported symbols, classes, interfaces, or functions, especially in large TypeScript projects. This server streamlines this process, enabling AI code editors to instantly retrieve the exact location and code snippet of any TypeScript symbol.
2. Seamless Integration with AI Code Editors: The MCP server is designed to seamlessly integrate with various AI code editors that support the Model Context Protocol. This ensures a smooth and intuitive experience for developers, regardless of their preferred AI-assisted development environment.
3. Enhanced Code Understanding for AI Models: By providing AI models with precise symbol definitions, the server empowers them to offer more accurate code suggestions, completions, and refactoring recommendations. This leads to improved code quality and reduced development time.
4. Simplified Navigation of Complex Codebases: In projects with numerous dependencies and intricate file structures, navigating to the definition of a symbol can be a time-consuming task. The MCP server simplifies this process, allowing developers to quickly jump to the relevant code location with a single command.

Key Features

The TypeScript Definition Finder MCP Server boasts a range of features designed to maximize its utility and effectiveness:

• Finds Original Definitions: The server excels at locating the original definitions of TypeScript symbols, even those imported from external packages. This is crucial for understanding the behavior and usage of third-party libraries and modules.
• Works with Imported Symbols: Unlike traditional code analysis tools that may struggle with imported symbols, this MCP server seamlessly handles them, providing accurate definitions regardless of their origin.
• Returns Definition Location and Code Snippet: The server not only provides the file path and line number of the definition but also includes the actual code snippet, offering developers immediate context and clarity.
• Supports stdio Interface: The server utilizes the standard input/output (stdio) interface for seamless integration with AI code editors. This ensures compatibility with a wide range of development environments.
• Tool Description for AI Integration: The server provides a detailed tool description, including the tool name (find_typescript_definition), trigger command (/ts-def), and purpose, enabling AI code editors to effectively utilize its capabilities.
• Clear Input Parameter Specifications: The server defines the required input parameters (file_path, symbol, and line_content) with clear descriptions and examples, ensuring that AI code editors can provide the necessary information for accurate symbol definition lookup.
• Well-Defined Response Format: The server returns a JSON response containing the file path, line number, and code snippet of the definition, allowing AI code editors to easily parse and display the results to the developer.

Deep Dive: Input Parameters Explained

To fully leverage the capabilities of the TypeScript Definition Finder MCP Server, it’s crucial to understand the input parameters it requires:

1. file_path (string): This parameter specifies the absolute path to the current TypeScript file. It provides the server with the context of the code being analyzed. For instance, if you are working on a file named index.ts located in /path/to/your/project/src/, the file_path would be /path/to/your/project/src/index.ts.

2. symbol (string): This parameter represents the TypeScript symbol (variable, class name, interface, type, etc.) for which you want to find the definition. The symbol must be present in the line_content. For example, if you want to find the definition of StdioServerTransport, the symbol would be StdioServerTransport.

3. line_content (string): This parameter contains the entire line of code that includes the symbol you want to find the definition of. It is used to locate both the line number in the file and the exact position of the symbol. The line_content must contain the symbol exactly as specified. For instance, if the line of code is import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";, the line_content would be exactly that string.

Example Scenario

Let’s illustrate how the TypeScript Definition Finder MCP Server works with a practical example:

Suppose you have the following TypeScript code:

typescript import { StdioServerTransport } from “@modelcontextprotocol/sdk/server/stdio.js”;

class MyService { private transport: StdioServerTransport; }

To find the definition of StdioServerTransport, you would provide the following input parameters:

{ “file_path”: “/path/to/project/src/service.ts”, “symbol”: “StdioServerTransport”, “line_content”: " private transport: StdioServerTransport;" }

The server would then return a JSON response containing the file path, line number, and code snippet of the StdioServerTransport definition, allowing you to quickly navigate to the relevant code location.

Installation and Usage

To start using the TypeScript Definition Finder MCP Server, follow these simple steps:

1. Ensure TypeScript is Installed: Make sure your project has TypeScript installed as a dependency.

2. Run the MCP Server: Execute the following command in your project directory:

   bash npx -y ts-def-mcp@latest

   This command will start the MCP server, which will listen for requests from AI code editors.

3. Integrate with AI Code Editors: Configure your AI code editor to use the TypeScript Definition Finder MCP Server as a context provider. The specific steps for integration will vary depending on the AI code editor you are using.

Important Considerations

• Local Filesystem Access: The MCP server requires access to your local filesystem to find TypeScript definitions. Therefore, Docker + WebSocket solutions may not be suitable.
• Smithery Installation: While the server can be installed via Smithery, it’s important to note that the installation guide on https://smithery.ai/server/@runninghare/typescript-definition-finder-mcp may not be fully accurate due to the local filesystem access requirements.
