AiDex
Stop wasting 80% of your AI's context window on code searches.
AiDex is an MCP server that gives AI coding assistants instant access to your entire codebase through a persistent, pre-built index. Works with any MCP-compatible AI assistant: Claude Code, Claude Desktop, Cursor, Windsurf, Gemini CLI, VS Code Copilot, and more.

What's Inside — 30 Tools in One Server
| Category | Tools | What it does |
|---|---|---|
| Search & Index | init, query, update, remove, status |
Index your project, search identifiers by name (exact/contains/starts_with), time-based filtering |
| Signatures | signature, signatures |
Get classes + methods of any file without reading it — single file or glob pattern |
| Project Overview | summary, tree, describe, files |
Entry points, language breakdown, file tree with stats, file listing by type |
| Cross-Project | link, unlink, links, scan |
Link dependencies, discover indexed projects |
| Global Search | global_init, global_query, global_signatures, global_status, global_refresh |
Search across ALL your projects at once — "Have I ever written X?" |
| Guidelines | global_guideline |
Persistent AI instructions & coding conventions — shared across all projects |
| Sessions | session, note |
Track sessions, detect external changes, leave notes for next session (with searchable history) |
| Task Backlog | task, tasks |
Built-in task management with priorities, tags, and auto-logged history |
| Log Hub | log |
Universal log receiver — any program sends logs via HTTP, queryable by the AI, live in Viewer |
| Screenshots | screenshot, windows |
Cross-platform screen capture with LLM optimization — scale + color reduction saves up to 95% tokens |
| Viewer | viewer |
Interactive browser UI with file tree, signatures, tasks, logs, and live reload |
11 languages — C#, TypeScript, JavaScript, Rust, Python, C, C++, Java, Go, PHP, Ruby
Quick Examples — see it in action
# Find where "PlayerHealth" is defined — 1 call, ~50 tokens
aidex_query({ term: "PlayerHealth" })
→ Engine.cs:45, Player.cs:23, UI.cs:156
# All methods in a file — without reading the whole file
aidex_signature({ file: "src/Engine.cs" })
→ class GameEngine { Update(), Render(), LoadScene(), ... }
# What changed in the last 2 hours?
aidex_query({ term: "render", modified_since: "2h" })
# Search across ALL your projects at once
aidex_global_query({ term: "TransparentWindow", mode: "contains" })
→ Found in: LibWebAppGpu (3 hits), DebugViewer (1 hit)
# Leave a note for your next session
aidex_note({ path: ".", note: "Test the parser fix after restart" })
# Create a task while working
aidex_task({ path: ".", action: "create", title: "Fix edge case in parser", priority: 1, tags: "bug" })
The Problem
Every time your AI assistant searches for code, it:
- Greps through thousands of files → hundreds of results flood the context
- Reads file after file to understand the structure → more context consumed
- Forgets everything when the session ends → repeat from scratch
A single "Where is X defined?" question can eat 2,000+ tokens. Do that 10 times and you've burned half your context on navigation alone.
The Solution
Index once, query forever:
# Before: grep flooding your conte
