Akb
A Git-backed knowledge vault that gives agents structured read/write access to organizational memory. Exposes hybrid search (semantic plus BM25), document CRUD with frontmatter relations, per-document SQL tables, and a URI graph over MCP. Every write commits to a bare Git repo and indexes into PostgreSQL with pluggable vector stores. Works with Claude Desktop, Cursor, Windsurf via the akb-mcp stdio proxy, or direct HTTP with bearer tokens. Ships agent plugins for Claude Code that auto-capture session notes and inject vault context into coding workflows. Reach for this when you need agents to maintain long-term memory across sessions with full version history and cross-document links, not just ephemeral context windows.

Readme
AKB — agents reading and writing into a permissioned knowledge vault of docs, tables, and files, linked by a URI graph
AKB — Agent Knowledge Base
Organizational memory for AI agents. PostgreSQL-native knowledge base served over the Model Context Protocol (MCP) — agents read and write directly with hybrid semantic + keyword search, structured tables, files, and a URI graph. Drop-in alternative to Confluence / Notion for Claude Code, Cursor, Windsurf, and any MCP-aware agent.
Works with
Any agent client that speaks MCP (Streamable HTTP or stdio):
