"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.

Enables coding agents to use an Obsidian vault as long-term memory, with search, reading, and writing of notes, plus automatic capture of learnings that are propagated to MOCs, daily notes, and the knowledge index with git commits.

MCP server providing persistent memory for AI applications, enabling Claude to store and recall memories with hybrid search and knowledge graph.

Markdown + SQLite knowledge store with bidirectional wikilinks, exposed as an MCP server for AI agents to maintain an interconnected knowledge base.

MCP server for intelligent, use-adaptive Obsidian vault search. It uses Hebbian learning and graph centrality to rank files by usage and relevance.

Mimir is Perseus's external persistent memory backend — a lightweight Rust MCP server that stores cross-session facts so agents remember what they learned last week. Zero network calls, no API keys, just SQLite + FTS5 running alongside your workspace.

A personal code snippet library for Claude, enabling saving, searching, and managing code snippets across sessions and projects.

Provides cross-session persistent memory for coding agents via MCP tools to store, retrieve, and manage notes with hybrid keyword/semantic search and automatic deduplication.

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.

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.

Local-first Obsidian vault MCP bridge with frontmatter queries, daily notes, stateless protocol

Local-first agentic knowledge layer over Obsidian notes, enabling MCP-aware agents to search, retrieve, and compile knowledge with provenance and task contracts.

MCP server that provides a navigable map of an Obsidian vault for coding agents, with tools to outline notes, fetch sections, query frontmatter, and grep content, reducing token usage compared to reading whole notes.

Gives AI clients OAuth-secured, remote read and approval-gated write access to an Obsidian vault, including search, backlinks, diffs, and audited proposals. It also proxies a headless Anki container through a scoped MCP gateway for flashcard management.

An MCP server for personal markdown notes that enables hybrid search (keyword + semantic) with Reciprocal Rank Fusion, allowing users to save, search, update, and retrieve notes by meaning rather than exact wording.

Enables semantic recommendation for Obsidian vaults, allowing users to find related notes, forgotten knowledge, and missing connections through embedding similarity and wiki-link graph analysis.

Enables private, self-hosted storage and semantic/full-text retrieval of durable facts extracted from conversations, with provenance, corrections, conflict records, and scoped bearer authentication.

MCP server for browsing Obsidian-compatible Markdown vaults, searching notes, viewing backlinks and knowledge graphs, and adding selected content to chat context.

MCP server for intelligent, use-adaptive Obsidian vault search, ranking files via BM25, PageRank, and Hebbian usage signals. Enables hybrid ranked search, neighboring-note discovery, and vault analytics.

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