Architecture

All-in-MCP uses a modern FastMCP architecture with two main components:

1. 🔄 All-in-MCP Proxy Server: Main server that routes requests to academic tools
2. 📚 APaper Module: Isolated academic research server with specialized paper search tools

This design provides better modularity, performance, and scalability.

Features

Both servers expose academic paper search tools as FastMCP endpoints with automatic tool registration:

Available Tools

Category	Tool Name	Description	Backend
Academic Research	apaper_search_iacr_papers	Search academic papers from IACR ePrint Archive	APaper
	apaper_download_iacr_paper	Download PDF of an IACR ePrint paper	APaper
	apaper_read_iacr_paper	Read and extract text content from an IACR ePrint paper PDF	APaper
Bibliography Search	apaper_search_cryptobib_papers	Search CryptoBib bibliography database for cryptography papers	APaper
Cross-platform Search	apaper_search_crossref_papers	Search academic papers from Crossref database	APaper
	apaper_search_google_scholar_papers	Search academic papers across disciplines with citation data	APaper
PDF Processing	apaper_read_pdf_file	Read and extract text from local and online PDF files	APaper
GitHub Repository	github-repo-mcp_getRepoAllDirectories	Get all directories from a GitHub repository	GitHub-Repo-MCP
	github-repo-mcp_getRepoDirectories	Get directories from a specific path in GitHub repository	GitHub-Repo-MCP
	github-repo-mcp_getRepoFile	Get file content from GitHub repository	GitHub-Repo-MCP

All tools are implemented using FastMCP decorators with automatic registration, built-in validation, and enhanced error handling.

Prerequisites

• Python 3.10 or higher
• pipx for Python package installation
• npx for MCP Inspector (Node.js required)

Integration with MCP Clients

Add the servers to your MCP client configuration:

VSCode Configuration (.vscode/mcp.json)

{
  "servers": {
    "all-in-mcp": {
      "type": "stdio",
      "command": "pipx",
      "args": ["run", "all-in-mcp"],
      "env": {
        "APAPER": "true",
        "GITHUB_REPO_MCP": "true"
      }
    }
  }
}

Claude Code Configuration (.mcp.json)

{
  "mcpServers": {
    "all-in-mcp": {
      "type": "stdio",
      "command": "pipx",
      "args": ["run", "all-in-mcp"],
      "env": {
        "APAPER": "true",
        "GITHUB_REPO_MCP": "true"
      }
    }
  }
}

Server Options

The main proxy server supports multiple MCP backends through environment variables:

# Run with APaper academic tools enabled
APAPER=true pipx run all-in-mcp

# Run with GitHub repository tools enabled
GITHUB_REPO_MCP=true pipx run all-in-mcp

# Run with both backends enabled
APAPER=true GITHUB_REPO_MCP=true pipx run all-in-mcp

# Run standalone APaper server (academic tools only)
pipx run apaper

Note: If you have the package installed globally, you can also run directly: all-in-mcp or apaper

Debugging & Testing

MCP Inspector

Use the official MCP Inspector to debug and test server functionality:

# Debug the main proxy server with APaper tools
APAPER=true npx @modelcontextprotocol/inspector pipx run all-in-mcp

# Debug with all backends enabled
APAPER=true GITHUB_REPO_MCP=true npx @modelcontextprotocol/inspector pipx run all-in-mcp

# Debug standalone APaper server
npx @modelcontextprotocol/inspector pipx run apaper

The MCP Inspector provides:

• 🔍 Interactive Tool Testing: Test all available tools with real parameters
• 📊 Server Information: View server capabilities and tool schemas
• 🐛 Debug Messages: Monitor server communication and error messages
• ⚡ Real-time Testing: Execute tools and see results immediately

Perfect for development, debugging, and understanding how the FastMCP tools work.
