Provides an AI agent with a searchable markdown notes vault, offering tools to create, read, list, search, update, and delete notes stored as plain .md files.

MCP server that lets agents create and update persistent concept maps via the NodeLand API, returning shareable URLs for humans to view, embed, and keep editing.

Enables MCP clients to safely read, search, create, edit, delete, and move notes in an Obsidian vault, with automatic link repair and reversible deletes.

A model context protocol server that allows interaction with TriliumNext Notes, providing tools to create, search, retrieve, update, and delete notes through natural language commands.

An MCP server that lets Claude or ChatGPT read, create, and edit mind maps stored in a GitHub repository, with support for local and HTTP transport.

Turns your PDFs into locally stored flashcards and quizzes, grades your answers, and schedules spaced-repetition reviews entirely on your machine.

An MCP server that enables LLM agents to list, read, create, update, delete, and search Apple Notes on macOS.

Enables MCP clients to read, search, list, and explore an Obsidian vault through coarse, intent-shaped tools, with optional read-only enforcement and a single write tool.

Enables natural language interaction with a local Obsidian vault, allowing MCP clients to read, search, create, append, and delete markdown notes securely.

An MCP server for Capacities API 2.0 that enables AI agents to discover, create, read, update, and delete objects, blocks, and daily notes with structured JSON or Markdown, using personal API tokens.

Enables MCP-compatible clients such as Claude to list, retrieve, create, update, append to, and delete Nextcloud Notes, manage categories, and read or update app settings.

An MCP server for a plain-markdown LLM wiki vault with YAML frontmatter and Obsidian-style wiki-links, enabling headless full-text search, note reading, backlink discovery, and safe append/create-only writing with path traversal protection and an immutable raw/ directory.

Enables AI agents to list, create, update, upsert, and delete calendar events that are stored as notes in a self-hosted Trilium instance, exposing tool names and arguments interchangeable with the Nextcloud Calendar MCP. Events carry stable UIDs, timezone-aware start/end and inclusive all-day semantics, tags, locations and recurrence, and the same notes can be served to standard calendar clients over CalDAV.

Enables seamless interaction with Voicenotes through natural language, allowing users to search, create, edit, tag, and organize their notes via an MCP client like Claude.

An MCP server that enables Claude Code to create, manage, and search Anki flashcards directly from the terminal. It supports batch card creation, deck statistics retrieval, and synchronization with AnkiWeb for cross-platform review.

Provides AI coding agents with a local, Markdown-first shared memory, enabling them to record decisions, failures, progress, and handoffs and retrieve them across sessions via MCP tools.

An MCP server for Things 3 on macOS that enables AI assistants to create, read, update, and manage tasks and projects. It utilizes the Things URL scheme for write operations and AppleScript for querying data from the app.

A local MCP server for low-token co-reading: import a book, split it into chapter-sized chunks, read it chunk by chunk, and keep notes so a session can resume without re-reading the whole book.
