Introduction

MCP Advisor is a discovery and recommendation service that helps AI assistants explore Model Context Protocol (MCP) servers using natural language queries. It makes it easier for users to find and leverage MCP tools suitable for specific tasks.

User Stories

  1. Discover & Recommend MCP Servers

    • As an AI agent developer, I want to quickly find the right MCP servers for a specific task using natural-language queries.
    • Example prompt: "Find MCP servers for insurance risk analysis"

  2. Install & Configure MCP Servers

    • As a regular user who discovers a useful MCP server, I want to install and start using it as quickly as possible.
    • Example prompt: "Install this MCP: https://github.com/Deepractice/PromptX"

Demo

Usage

Once configured, the Nacos provider will be automatically enabled and used when searching for MCP servers. You can query it using natural language, for example:

Find MCP servers for insurance risk analysis

Or more specifically:

Search for MCP servers with natural language processing capabilities

Quick Start

Installation

The fastest way is to integrate MCP Advisor through MCP configuration:

{
  "mcpServers": {
    "mcpadvisor": {
      "command": "npx",
      "args": ["-y", "@xiaohui-wang/mcpadvisor"]
    }
  }
}

Add this configuration to your AI assistant's MCP settings file:

  • MacOS/Linux: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %AppData%\Claude\claude_desktop_config.json

Installing via Smithery

To install Advisor for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @istarwyh/mcpadvisor --client claude

For more installation methods and detailed configuration, see the Quick Start Guide.

Architecture Overview

MCP Advisor adopts a modular architecture with clean separation of concerns and functional programming principles. The codebase has been recently refactored (2025) to improve maintainability and scalability:

Troubleshooting

Common Issues

  1. Connection Refused

    • Ensure the server is running on the specified port
    • Check firewall settings

  2. No Results Returned

    • Try a more general query
    • Check network connection to registry APIs

  3. Performance Issues

    • Consider adding more specific search terms
    • Check server resources (CPU/memory)

For more troubleshooting information, see TROUBLESHOOTING.md.

Search Providers

MCP Advisor supports multiple search providers that can be used simultaneously:

  1. Compass Search Provider: Retrieves MCP server information using the Compass API
  2. GetMCP Search Provider: Uses the GetMCP API and vector search for semantic matching
  3. Meilisearch Search Provider: Uses Meilisearch for fast, fault-tolerant text search

For detailed information about search providers, see Technical Reference.

Roadmap

MCP Advisor is evolving from a simple recommendation system to an intelligent agent orchestration platform. Our vision is to create a system that not only recommends the right MCP servers but also learns from interactions and helps agents dynamically plan and execute complex tasks.
