"Vault" matching MCP servers:

Enables AI agents to persist and retrieve structured memory across sessions and models via MCP tools for cataloging, searching, and saving facts, with automatic supersession and scope filtering.

RAG Vault lets your AI coding assistant search your private documents locally. Everything runs on your machine and your data stays private.

MCP server that exposes an Obsidian-style markdown vault as a shared memory for AI agents, with tools for searching, reading, writing, and querying notes and wiki-links.

Provides persistent knowledge capture and retrieval for coding agents. Enables searching the vault, storing notes, capturing sessions, and reading notes via MCP tools.

A remote MCP server that enables language models to search, read, and write notes in an Obsidian vault organized with the PARA method, and save URLs as notes.

Centralized credential management for servers, websites, and APIs with HashiCorp Vault integration. Provides authentication, authorization, and audit logging for secure access to secrets.

A self-hostable semantic skill registry for AI agents, providing searchable, versioned, and verified skills over a single MCP endpoint with per-agent private vaults and trust tiers.

Remote MCP server for Obsidian vaults, enabling secure access to markdown notes from Claude clients without the Obsidian desktop app. Provides tools for searching, reading, listing recent notes, resolving daily notes, and creating/appending notes via HTTPS.

Human-in-the-loop secret access for AI coding agents, enabling approval workflow for password manager secrets via MCP.

Self-hosted MCP server that syncs Xiaomi fitness data to SQLite and provides authenticated tools to query health metrics (steps, sleep, HR, etc.) for AI assistants like Grok.

Enables agents to securely use credentials for GitHub, Cloudflare, OpenAI, Stripe, and xAI without ever reading the secret values, including credential health, rotation, and audit features.

A generic Markdown vault MCP server with FTS5 full-text search, semantic vector search, frontmatter-aware indexing, incremental reindexing, and non-markdown attachment support that exposes search, read, write, and edit tools.

Enables Claude Code to read and write an Obsidian-style markdown vault stored locally or in S3, with indexed full-text search, schema validation, linting, and session hooks.

Enables reading, searching, and modifying Obsidian vault notes directly, including saving conversation summaries and appending to daily notes, with GitHub OAuth authentication.

Enables ChatGPT, Codex, and other AI clients to search, read, create, and carefully update Markdown notes in an Obsidian vault, either locally over stdio or on a VPS via Syncthing and an OpenAI Secure MCP Tunnel, while blocking writes when a file changed since it was last read.

Enables reading, searching, and writing an Obsidian vault directly on disk without Obsidian running, and walking its wikilink graph for backlinks, N-hop neighbors, unresolved links, and orphans. Available over Streamable HTTP with bearer auth, stdio, or a Claude Desktop extension.

Enables AI clients to read, write, search, and manage files in an Obsidian vault via MCP over SSE, running standalone without the Obsidian desktop app.

Enables AI assistants to search, read, and traverse Markdown note vaults (Obsidian-compatible) with full-text search, backlinks, knowledge graphs, and a persistent memory system for cross-session context.

Headless semantic MCP server for Obsidian, Logseq, Dendron, Foam, and any markdown folder. Features built-in hybrid semantic search, surgical AST editing, template scaffolding, zero-config local embeddings, and workflow tracking.

Governed, tamper-evident memory and audit trail for AI agents with 0G Merkle segment sealing. Records agent actions in append-only namespaces with hash chaining, seals segments to 0G Storage, and supports audits and retention enforcement.
