OpenMCP Client

Detailed Introduction

OpenMCP Client is an open-source toolkit for MCP (Model Context Protocol) developers that bundles a VS Code plugin, dedicated debugging panels, and a companion SDK for local testing, interactive validation, and project-level management. It consolidates prompt management, tool integration testing, and interactive debugging into a visual workflow, enabling developers to reproduce and iterate agent behavior and tool calls locally and shorten the turnaround from debugging to deployment.

Main Features

• Integrated debugging panels to manage MCP services, tool tests, and interaction history for easier troubleshooting.
• VS Code integration with plugin support for breakpoints, live logs, and configuration sync.
• Fast deployment path via openmcp-sdk to package debugged MCP configurations into deployable agent applications.
• Extensive examples, documentation, and community channels (documentation site and Discord) for onboarding and collaboration.

Use Cases

• Local debugging and interactive testing of MCP agents and tool integrations.
• Iterative prompt and toolchain development with quick validation and regression checks.
• Exporting tested MCP configurations and deploying them as runnable agent services via openmcp-sdk.

Technical Features

• Built with Vue and TypeScript, offering an extensible renderer and plugin architecture.
• Supports multi-model and multi-protocol integrations, compatible with common LLM providers and custom model endpoints.
• Project-level configuration and test-case management with versioning and CI-friendly workflows for reproducibility.
• Licensed under Apache-2.0 with active examples and community contributions.
