"Open Collective" matching MCP servers:

Persistent sticky notes for Claude Code. You pin a note — a decision, a blocker, a todo — and it survives session resets, /clear, and closing the terminal. Next time you open Claude in that project, the notes that still matter are handed back to it automatically.

A local, open-source MCP server that provides deterministic organizational tools for structured decisions, guided reflection, action planning, and transparent digital report outlines without requiring an API key.

Open-source MCP server giving Claude persistent project memory via plain markdown files. Local-first workspace with 11 tools for projects, tasks, sessions, and notes.

Enables AI models to interact with the Get笔记 (GetNotes) platform via its Open API. It supports managing notes, organizing knowledge bases, and handling tags through natural language commands.

Enables interaction with Apple apps like Messages, Notes, and Contacts through the MCP protocol to send messages, search, and open app content using natural language.

Enables AI assistants to manage notebooks, sources, notes, search content, and interact with AI models through Open Notebook.

Enables AI assistants to search, read, create, and modify Markdown notes in local Obsidian vaults directly through filesystem operations. Supports tag-based discovery and frontmatter parsing without requiring Obsidian to be open, facilitating integration with VS Code Copilot via stdio transport.

A free, open-source Markdown editor with a bundled MCP server (stdio, read-only): point Claude, Cursor, or any MCP client at your notes vault for local semantic search, read, and list. ~15MB, 5 platforms, MIT, local-first.

An open-source memory layer that provides persistent project context and architectural history for AI development tools across multiple platforms and sessions. It enables AI assistants to maintain a shared understanding of codebases while integrating directly with services like Notion for documentation management.

Enables Claude Code to interact with Bear notes on macOS, supporting create, search, update, delete, open notes, and tag management via natural language.

Enables LLM clients to browse and query your Zotero library through tool calls. Provides access to Zotero-specific functions like listing open tabs, searching items, and browsing collections via a local MCP server running inside Zotero.

Gives AI assistants persistent, shared memory using the Zettelkasten method, so they retain corrections, preferences, and decisions across sessions and across tools via local, hybrid search.

A mobile-first AI co-reading MCP server that lets users import novels or comics, sync reading progress with AI, and interact through comments, bookmarks, and notes.

Provides real-time weather data from Open-Meteo API and enables creating and retrieving notes stored locally in JSON format.

Exposes the Maimemo (墨墨背单词) Open API as MCP tools, enabling AI assistants to look up words, manage mnemonics and study plans, and maintain cloud notepads.

Enables Claude Desktop to directly access and manage Obsidian vault files, supporting reading, writing, patching, searching, and file operations without requiring Obsidian to be open.

An open-source MCP server that makes your Obsidian vault accessible from any AI client with hybrid search, read/write, and graph analysis capabilities.

Search, read, and create speech-to-text transcripts on-device with the Whisper Notes Mac app. The MCP server is built into the app (macOS, Apple Silicon) and serves over a local Unix socket — 100% offline, no open ports.

Open memory standard for AI agents. Local-first, MCP-native, lives in your Obsidian vault. Bi-temporal markdown, hybrid retrieval, reproducible benchmark.

A bridge between LLMs and OpenWebUI workspaces that enables managing projects, notes, and knowledge bases. It supports safe project configuration updates through a propose-evaluate-apply workflow and direct file uploads to knowledge bases.
