NoteDiscovery is a self-hosted plain-markdown notes app (MIT, no telemetry) with a built-in stdio MCP server. The server exposes tools so AI clients (Claude Desktop, Cursor, etc.) can search, read, create, edit, tag, and instantiate templates against the same vault the web UI uses.

Memory for Claude and coding agents, kept as markdown notes you own: a schema that holds, search that reads your languages, a lifecycle for tasks and decisions, and a tie to your git history. Runs on a folder, an S3 bucket or your own vault server.

A personal knowledge management system built on the Model Context Protocol that transforms daily notes into organized, searchable knowledge.

A fast, lightweight MCP server and CLI for Obsidian vaults built in Go. 16 multiplexed tools covering 72 actions for notes, search, templates, tasks, links, frontmatter, and vault analysis. Single binary, no plugins required.

Unofficial Notion MCP server built on Notion's private API (token_v2 cookie). Gives LLM agents full read/write access to the entire workspace — no integration token and no per-page sharing.

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.

A TypeScript-based MCP server built on the Gmail API that implements a simple notes system. It enables users to create, manage, and summarize text-based notes through specialized resources and tools.

Provides API tools to interact with Yonote documents and collections, serving as an alternative to Notion with capabilities to list documents/collections and retrieve detailed document information.

Persistent docs and memory for AI agents. Writespace is a collaborative markdown editor with a built-in MCP server — your model reads, writes, organizes, and searches a shared workspace while humans edit the same docs live. Drop the ranked full-text search straight in as RAG retrieval.

Local-first markdown vault with a built-in MCP server (streamable HTTP). 16 tools and 2 resources for Claude Code / Desktop / Cursor: read/write/search plus context_for_query, find_orphans, weekly_digest, compare_notes, semantic_outline.

A minimal Python MCP server that gives Claude access to built-in Apple apps (Mail, Contacts, Calendar, Notes, Reminders) on macOS, leveraging native APIs and local databases for speed with no OAuth setup.

Enables voice-driven daily reflection journaling via MCP, including reflection prompts, an optional Four-Pillars (saju) lens, journal entries with streaks, and history retrieval, with built-in provenance and crisis checks.

Enables assistants to maintain an append-only memory for personal context that should not be stored in their built-in memory, with tools for noting, recalling, and compressing memories.

Local Markdown/HTML note-taking app with built-in MCP server, agentic workflow runtime engine, wikilinks, and state-machine approval gates.

A privacy-first MCP server that converts messy multi-turn conversations into structured, durable knowledge cards, targeting non-programming agent workflows.

Enables OAuth-only clients such as claude.ai to use Trilium Notes' built-in MCP tools by handling browser login and forwarding requests to Trilium with each client's ETAPI token.

Enables automated access to programming problems, contests, solutions, and public or authenticated user data across global and China sites, including private notes, problem lists, progress tracking, code execution, and submission analysis.

Connects AI agents to a Notion workspace with token-based authentication, letting them create and edit pages, query databases, append blocks, apply templates, comment, and upload or read files through plain-language requests. Its three-tool, context-efficient design and built-in batched, idempotent operations support headless automation in CI, cron jobs, and self-hosted agents.
