hive-vault 1.11.5

Unified MCP server for AI-assisted development — on-demand Obsidian vault access + worker delegation

hive-vault

Your AI coding assistant forgets everything between sessions. Hive fixes that.

Hive is an MCP server that connects your AI assistant to an Obsidian vault. Instead of loading everything upfront, it queries only what's needed — on demand.

Metric	Without Hive	With Hive
Context loaded per session	~800 lines (static)	~50 lines (on demand)
Token cost for context	100% every session	6% average per query
Knowledge retained between sessions	0%	100% (in vault)

Measured on a real vault with 19 projects, 200+ files. See benchmarks.

Quick Start

# Claude Code
claude mcp add -s user hive -e VAULT_PATH=$HOME/path/to/vault -- uvx --upgrade hive-vault

# Gemini CLI
gemini mcp add -s user -e VAULT_PATH=$HOME/path/to/vault hive-vault uvx -- --upgrade hive-vault

Set VAULT_PATH to your Obsidian vault directory. Default: ~/Projects/knowledge.

For Codex CLI, GitHub Copilot, Cursor, Windsurf, and other clients, see Getting Started.

Then ask your assistant: "Use vault_list to see my vault"

Tools

Tool	What it does
vault_query	Load project context, tasks, roadmap, lessons — or any file by path
vault_search	Full-text search with metadata filters, regex, ranked results, recent changes
vault_list	Browse projects and files with glob filtering
vault_health	Health metrics, drift detection, usage stats
vault_write	Create, append, or replace vault files with auto git commit
vault_patch	Surgical find-and-replace with auto git commit
capture_lesson	Capture lessons inline or batch-extract from text via worker
session_briefing	Tasks + lessons + git log + health in one call
delegate_task	Route tasks to cheaper models or summarize vault files
worker_status	Budget, connectivity, available models

Plus 5 resources and 4 prompts for guided workflows.
