What Devbrain does

Single Source of Truth (SSOT) for Multi-Agent Coding & Obsidian. devbrain connects your AI coding assistants (Google Antigravity IDE, Claude Code, Hermes, OpenCode) directly to a local Obsidian Vault using the Model Context Protocol (MCP) and high-speed Hybrid Semantic Search (FastEmbed CPU ONNX + Rank-BM25).

README

🧠 devbrain — Central AI Second Brain Hub

**Single Source of Truth (SSOT) for Multi-Agent Coding & Obsidian.**

`devbrain` connects your AI coding assistants (**Google Antigravity IDE**, **Claude Code**, **Hermes**, **OpenCode**) directly to a local **Obsidian Vault** using the **Model Context Protocol (MCP)** and high-speed **Hybrid Semantic Search** (FastEmbed CPU ONNX + Rank-BM25).

⚡ 30-Second Quickstart

1. Install `devbrain` in Editable Development Mode

cd "E:\_PROJECT\_Central AI Brain Hub"
pip install -e .

*(Once installed, you can use the global `devbrain` command directly from any folder)*

2. Initialize or Attach Your Obsidian Vault

devbrain init E:/MyObsidianVault

*(Or via Python module directly: `python -m devbrain.cli.main init E:/MyObsidianVault`)*

*What happens under the hood:*

Scaffolds the standard 07 Obsidian taxonomy (00_System/, 10_Projects/, 20_Knowledge/, 30_Decisions/, 90_Agent_Inbox/, 99_Daily/, .brainignore).
Automatically registers the central-brain FastMCP server into Google Antigravity IDE (~/.gemini/antigravity/mcp_config.json) and Claude Code (~/.claude.json).

3. Verify Vault Health

🤖 AI Agent FastMCP Pairing

Once initialized, your AI assistants in Antigravity IDE and Claude Code automatically gain access to 4 native memory tools:

MCP Tool	Purpose	Example Interaction
`search_brain(query, limit, scope)`	Semantic hybrid search across all vault notes	"Search our architectural guidelines on JWT authentication"
`get_project_context(project_name)`	Retrieve active project specs, backlog, and architecture from `10_Projects/`	"Load context and requirements for the auth_service project"
