Trilium Notes

Hierarchical note tree with attributes and scripting, driven by the ETAPI REST API and an in-repo MCP route.

Free

Use it when
  • you want a deeply nested personal or team knowledge tree that an agent can populate through a stable REST API
  • you outgrew flat markdown folders and want attributes, relations, and saved searches
An agent cannot reach
  • Scripting and widgets
  • Sync and protected (encrypted) notes
Gotchas
  • AGPL-3.0
  • The desktop app and server versions must match for sync; disable auto-updates on the server when using TriliumDroid
  • ETAPI needs a token created in the UI (Options > ETAPI) or from POST /etapi/auth/login with the instance password
  • MCP route tool names were not read; they come from the core LLM tool registry (packages/core llm/tools)

Anytype

Local-first encrypted knowledge OS with an official MCP server (@anyproto/anytype-mcp) over its local API.

Free: Free · Paid memberships

Use it when
  • you want a Notion-like object database that stays encrypted on your devices and an agent that can file objects into it
  • you need offline-first notes that sync peer-to-peer without a server you run
An agent cannot reach
  • Sync, encryption, and key management
  • Publish pages to the web

2 more jobs are undetermined.

Gotchas
  • Any Source Available License 1.0: modification and redistribution only for non-commercial use or within allowed networks; not open source
  • The desktop app (or anytype-cli) must be running; the MCP talks to 127.0.0.1:31009 and needs an API key from App Settings
  • API calls carry a version header (Anytype-Version 2025-11-08); bump it when the API changes
  • Membership prices could not be read from anytype.io (client-rendered page)

Joplin

Open-source notes app with an in-app MCP server, a local Data API, and paid Joplin Cloud sync.

Free apps · Joplin Cloud Basic: €3 per month · Joplin Cloud Pro: €6 per month · Joplin Cloud Teams: €8 per month · Joplin Server Business: €3 per month

Use it when
  • you already keep years of notes in Joplin and want Claude to search and write them without leaving the app
  • you want encrypted cross-device notes and are happy to pay a few euros a month for sync
An agent cannot reach
  • Upload attachments and resources
  • Sync, encryption, sharing, and publishing
  • Plugins and web clipper

1 more job is undetermined.

Gotchas
  • The MCP server runs inside the desktop app; the app must be open and the service enabled
  • packages/server (Joplin Server) is under a Personal Use License, not AGPL; business self-hosting requires the paid Joplin Server Business
  • Notebook delete and resource upload are not in the MCP tool set; fall back to the Data API on port 41184
