NEXUSThe Documentation Oracle for AI
Persistent memory, documentation search, and MCP server discovery for AI coding assistants
Skip to content
Documentation Search
Semantic search across 500+ indexed libraries. Get accurate, up-to-date code examples without hallucinations.
Persistent Memory
Your AI remembers your projects across sessions. Store decisions, conventions, and learnings.
MCP Server Registry
Discover and configure MCP servers for databases, APIs, and cloud services with copy-paste configs.
Token Efficiency
Semantic search returns only relevant chunks. Save 90%+ on context tokens compared to full docs.
Quick Start
Add Nexus to your AI client in 30 seconds:
Add to Claude Code
claude mcp add nexus -- npx -y @anthropic-ai/mcp-remote https://api.nexus.yogan.dev/sseAdded MCP server nexus
Or add directly to your MCP config file:
json
{
"mcpServers": {
"nexus": {
"url": "https://api.nexus.yogan.dev/sse"
}
}

Token Savings
Context is expensive. Nexus uses semantic search to return only the relevant chunks instead of entire documentation pages.
