MCP Assistant

Web-based MCP client for remote servers and AI tool workflows.

🌐 Overview

MCP Assistant addresses common pain points when working with the Model Context Protocol:

✨ Why MCP Assistant

• Connect to remote MCP servers from one interface
• Manage multiple MCP servers from a single interface
• Handle OAuth 2.0 and OpenID Connect flows without manual token juggling
• Explore available tools and run them directly from the UI
• Monitor connections in real time while testing and debugging integrations
• Work from anywhere without local MCP server setup

🚀 Core Capabilities

• Connect and manage MCP servers from a single workspace
• Discover available tools and execute them from the UI
• Use the local gateway to expose machine-local MCP tools through one endpoint
• Use the same endpoint from any MCP-compatible client (for example: ChatGPT, Claude, and others)
• Enable selected local gateway servers for Playground agent tool execution
• Handle OAuth/OIDC auth flows for protected MCP servers
• Browse registry servers and test integrations before production use

🏗️ Architecture

Local Gateway for ChatGPT, Claude, and Other MCP Clients

MCP Assistant includes a local gateway that exposes your configured MCP servers through one local endpoint, so desktop/web clients can connect without reconfiguring each remote server.

⚡ Gateway Quickstart

1. Install and run the gateway:

uvx mcpassistant-gateway

2. Log in from the gateway CLI using /login.
3. Start the bridge using /start.
4. Open the Gateway page in MCP Assistant and copy your generated MCP URL.
5. Use that URL in your MCP client (for example: ChatGPT, Claude, or the MCP Assistant Playground).
