A MongoDB Atlas-based Notion-style knowledge base management MCP server that supports user workspaces, project management, page CRUD with tree structure, and text search.

Local MCP server that gives an agent access to branches of your Tinhead tree. It handles account key unwrapping locally and enforces branch grants.

Enables AI agents to read and write to an iPad whiteboard via MCP, including structured elements, handwritten text, and image rendering.

An MCP server that gives AI agents durable, temporal memory over local markdown vaults, with tools for searching, asserting facts, querying point-in-time state, and reinforcing useful knowledge.

A self-hosted, token-scoped Model Context Protocol server for AppFlowy. It gives AI agents tools to read and edit your AppFlowy workspaces while bounding each client to exactly the pages you allow via per-token tree-shaped scopes.

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

Enables secure local interaction with RemNote through MCP, exposing semantic operations for notes, documents, editor state, panes, review queues, and knowledge-base metadata.

Enables users to add, get, and list notes, with state persisted to a JSON file in the home directory.

A permissioned memory tree for you and your AI — served over MCP.

Read-only MCP server that exposes an Obsidian vault to LLM clients over Streamable HTTP, letting them browse the accessible tree, read notes, run full-text searches, and resolve wiki-links and backlinks within a share-filtered note set. Access is limited by an operator-editable sharing config that is default-deny and never writes to the vault.
