Openmcp Client, developed by Lstm Kirigaya, is a free VS Code plugin designed for interacting with and developing MCP (Model Context Protocol) servers. Built with TypeScript and Vue Router, and running on a Node.js runtime environment, it serves as an all-in-one debugging solution for AI agents and web automation. While categorized as an MCP client and development tool, not an MCP server itself, it provides essential capabilities for connecting to, testing, and managing MCP server projects. Developers can access it via the VS Code Marketplace, complementing it with the openmcp-sdk.js for agent deployment.

What does Openmcp Client connect to?

Openmcp Client connects to MCP (Model Context Protocol) servers. These servers empower AI agents with capabilities for web automation and access to various services. It functions as an MCP client and a development/debugging tool, specifically integrated as a VS Code plugin. It is crucial to distinguish Openmcp Client as a client and development aid for MCP servers, rather than an MCP server itself. It helps developers build and manage the servers that AI agents interact with.

Core features and tools

As a VS Code plugin, Openmcp Client exposes tools for debugging, testing, and project management within the MCP development process. It provides methods to discover available tools on an MCP server, execute them with specific parameters, access resources, and interact with prompt systems. The associated openmcp-sdk.js allows developers to load MCP configurations using agent.loadMcpConfig and execute tasks with agent.ainvoke, aiding in agent deployment and interaction.

Who is it for?

Openmcp Client is designed for developers and AI researchers, particularly those engaged in building and managing MCP servers and AI agents. It supports concrete workflows like real-time debugging, interactive testing, and packaging MCP servers for deployment. Its features are tailored for individuals who need to develop, debug, and interact with Model Context Protocol environments. This is not the right fit if you are solely seeking an MCP server without development or debugging needs.

How to get started

Access is granted through a standard OAuth authorization flow, especially for remote connections. For local STDIO transport, authentication might use environment variables or system credentials.

Use cases

• Debugging MCP servers with features such as real-time debugging, multi-server support, and LLM integration.
• Interactively testing MCP servers using a built-in chat interface and tool invocation panel.
• Packaging and deploying MCP servers or debugged workflows as agents to various platforms, including cloud deployment, using the openmcp-sdk.js.

Openmcp Client offers a specialized environment for developing and interacting with MCP servers and AI agents. Its integration as a VS Code plugin, combined with debugging and testing capabilities, makes it a targeted solution for its audience. The support for various communication protocols and authentication methods ensures flexibility in development.
