MCP Support¶
Complete guide to Model Context Protocol (MCP) integration with ToolUniverse
ToolUniverse provides comprehensive support for the Model Context Protocol (MCP), enabling seamless integration with AI assistants, reasoning models, and agentic systems. This guide covers everything you need to know about using ToolUniverse through MCP.
What is MCP?¶
The Model Context Protocol (MCP) is a standardized protocol that enables AI assistants to securely connect to external tools and data sources. ToolUniverse implements MCP through the Scientific Model Context Protocol (SMCP), extending standard MCP capabilities with scientific domain expertise.
Key Benefits: - Standardized Integration: Connect to any MCP-compatible AI assistant - Scientific Tool Access: Direct access to 600+ scientific tools - Intelligent Discovery: AI-powered tool search and recommendation - Secure Communication: Standardized protocol ensures secure tool execution - Production Ready: High-performance architecture for real-world applications

ToolUniverse MCP Implementation¶
ToolUniverse provides two main MCP server implementations:
`tooluniverse-smcp` - Full-featured server with configurable transport (HTTP, SSE, stdio)
`tooluniverse-smcp-stdio` - Specialized server for stdio transport (optimized for desktop AI applications)
Both servers expose the same comprehensive set of scientific tools through the MCP protocol.
Quick Start¶
For basic MCP server setup and configuration, see the comprehensive guide in MCP Server Functions.
MCP Server Configuration¶
Transport Options¶
ToolUniverse MCP servers support multiple transport protocols:
- HTTP Transport (Default)
Best for web-based applications and remote access
Supports RESTful API endpoints
Configurable host and port
- STDIO Transport
Optimized for desktop AI applications
Direct process communication
Lower latency for local applications
- Server-Sent Events (SSE)
Real-time streaming capabilities
Suitable for interactive applications
Supports long-running operations
Tool Selection¶
Configure which tools are available through the MCP server. For detailed configuration options including category-based loading, tool-specific loading, and type-based filtering, see Category-Based Loading, Tool-Specific Loading, and Type-Based Filtering.
