AiDex
The persistent brain for AI coding agents.
AiDex is an MCP server that gives AI coding assistants a memory, semantic search, and live telemetry — local-first, model-agnostic. Works with any MCP-compatible AI assistant: Claude Code, Claude Desktop, Cursor, Windsurf, Gemini CLI, VS Code Copilot, and more.
Three Pillars
🧠 Memory — Tasks, notes, and session-notes survive every chat. Auto-logged history, scheduled tasks, cross-session continuity. Your AI knows tomorrow what mattered today.
🔍 Search — Three modes: exact (identifier), semantic (concept), hybrid (RRF fusion of both). Embeds code, docs, and workspace items into one ranking. Cross-project — every repo in one query. Optional LLM layer translates non-English queries and reranks results.
🌐 Telemetry — LogHub receives live logs from any app via HTTP (no SDK). The AI watches what your code actually does, not just what it says. Live-streamed in the Viewer.
And yes — it's still 50× more token-efficient than grep.
| Without AiDex | With AiDex | |
|---|---|---|
Find PlayerHealth |
Grep → 200 hits in 40 files → reads 5 files → 2,000+ tokens | 1 query → 3 exact locations → ~50 tokens |
| Get file structure | Reads entire 500-line file → 1,500 tokens | Signatures → classes + methods → ~80 tokens |
| What changed today? | git diff + grep + context → 3,000+ tokens |
Time-filtered query → ~50 tokens |
