Joplin MCP Server
Joplin MCP server enabling AI agents to interact with Joplin — the open-source, end-to-end encrypted note-taking and to-do application — reading and creating notes, managing notebooks and tags, searching note content, and integrating Joplin's personal knowledge management into agent-driven productivity and information retrieval workflows.

⚙ Agent Friendliness
🔒 Security
Local Joplin API. API token. Notes are personal data. Localhost only. Community MCP.
⚡ Reliability
Best When
A personal productivity agent needs to access Joplin notes for context, search, or organization — particularly for users who prefer Joplin's open-source, privacy-first approach.
Avoid When
Your team uses Obsidian, Notion, or other note-taking platforms — use those dedicated MCPs instead.
Use Cases
- • Reading and searching personal notes from knowledge retrieval agents
- • Creating and organizing notes from information capture agents
- • Accessing meeting notes and research for context from productivity agents
- • Managing to-do items and tasks from task management agents
- • Building AI-powered note search and summarization from personal assistant agents
- • Syncing and organizing knowledge base from PKM workflow agents
Not For
- • Teams using Obsidian, Notion, or Roam Research (Joplin-specific API)
- • Enterprise knowledge management (Joplin is personal/small team focused)
- • Real-time collaborative editing (Joplin is primarily single-user)
Interface

Agent Metadata
Known Gotchas
- ⚠ Joplin must be running with Web Clipper plugin enabled — not a background service by default
- ⚠ API token changes after Joplin reinstall — update MCP configuration after reinstall
- ⚠ End-to-end encryption in Joplin sync doesn't protect local API access — local trust required
- ⚠ Large note libraries may have slow search — implement result limits for performance
- ⚠ Joplin API doesn't support note content watching/webhooks — polling required for changes
- ⚠ Community MCP — Joplin API is stable but MCP wrapper may lag behind Joplin releases
