Poznote
Self-hosted note-taking app with a REST API and an MCP server of about 60 tools.
Free
- you want a self-hosted notes app your coding agent can read and write over MCP
- you want read-only, write or admin scopes on what an agent may touch in your notes
- Manage users, OIDC sign-in and webhooks
- MCP is HTTP only and published on 127.0.0.1 by default; set POZNOTE_MCP_AUTH_TOKEN before exposing it
- In classic mode any client that reaches the MCP port can act on any profile
- MCP tools above POZNOTE_MCP_SCOPE are not registered at all
- Local accounts start with default passwords listed in docs/API-REST.md; change them before exposing Poznote
- PikaPods and the other hosts on poznote.com/hosting.html are third parties with their own prices
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
- 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
- Upload attachments and resources
- Sync, encryption, sharing, and publishing
- Plugins and web clipper
1 more job is undetermined.
- 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
