Docdex MCP server

Docdex

Turn your repository into fast, private context that humans and AI can trust.

Docdex is a local-first indexer and search daemon for documentation and source code. It sits between your raw files and your AI assistant, providing deterministic search, code intelligence, and persistent memory without ever uploading your code to a cloud vector store.

⚡ Why Docdex?

Most AI tools rely on "grep" (fast but dumb) or hosted RAG (slow and requires uploads). Docdex runs locally, understands code structure, and gives your AI agents a persistent memory.

🚀 Features

• 📚 Document Indexing: Rank and summarize repo documentation instantly.
• 🧠 AST & Impact Graph: Search by function intent and track downstream dependencies (supports Rust, Python, JS/TS, Go, Java, C++, and more).
• 💾 Repo Memory: Stores project facts, decisions, and notes locally.
• 👤 Agent Memory: Remembers user preferences (e.g., "Use concise bullet points") across different repositories.
• 🗂️ Conversation Memory: Imports transcripts, keeps wake-up bundles compact, and derives repo-scoped summaries, diary entries, and working memory.
• 🕸️ Temporal Knowledge Graph: Extracts entities, edges, episodes, and code-facing links from archived conversations for timeline and neighborhood queries.
• 🧭 Wake-Up + Project Map Context: Injects compact wake-up bundles, profile truth, and cached Project map: context into OpenAI-compatible chat completions.
• 🔌 MCP Native: Auto-configures for tools like Claude Desktop, Cursor, and Windsurf.
• 🌐 Web Enrichment: Optional web search with local LLM filtering through detected local LLM services.

📦 Set-and-Forget Install

Install once, point your agent at Docdex, and it keeps working in the background.

1. Install via npm (Recommended)

Requires Node.js >= 18. This will download the correct binary for your OS (macOS, Linux, Windows).

npm i -g docdex

[!WARNING]

Windows requirement: Docdex uses the MSVC runtime. Install the Microsoft Visual C++ Redistributable 2015-2022 (x64) before running docdex/docdexd.

- Winget: winget install --id Microsoft.VCRedist.2015+.x64

- Manual: download vcredist.x64.exe from Microsoft: https://aka.ms/vs/17/release/vcredist.x64.exe

- If docdexd exits with 0xC0000135, the runtime is missing.

2. Auto-Configuration

If you have any of the following clients installed, Docdex automatically configures them to use the local MCP endpoint (daemon HTTP/SSE):

Claude Desktop, Cursor, Windsurf, Cline, Roo Code, Continue, VS Code, PearAI, Void, Zed, Codex.

Note: Restart your AI client after installation.

🛠️ Usage Workflow

1. Index a Repository

Run this once to build the index and graph data.

docdexd index --repo /path/to/my-project

2. Start the Daemon

Start the shared server. This handles HTTP requests and MCP connections.

docdex start
