Vault

Vault is a Model Context Protocol (MCP) server designed to bridge AI agents, such as Claude Code, with a local markdown knowledge vault. It transforms a directory of `.md` files—containing project documentation, knowledge crystals, session states, and chronicles—into a structured set of tools. This enables AI agents to read, search, and write to the vault securely, complete with robust built-in guardrails to manage immutability, enforce frontmatter, limit line counts, and prevent secret exposure. It provides a reliable and controlled knowledge base, facilitating AI-driven workflows that require access to and interaction with local documentation and research.
