Which notes apps have an MCP server: eight compared
Notion, Obsidian, Apple Notes, Evernote, Craft, Reflect, Inkdrop and Sumibako: who makes each MCP server, where it runs, and what an AI agent can do with it.

"Can Claude write to my notes?" has a different answer for every notes app, and most of the answers online are a year old, which in this field is roughly the Bronze Age.
So I went to each maker's own documentation and wrote down what it says. Eight apps, the same four questions each, checked on 27 September 2026. Notion's tool list was counted again on 12 October: it had changed, so this post now says "more than thirty" where it said 37. One of the eight is mine. It gets the same columns as the rest, and I have tried to be as hard on it.
If you are in a hurry, the table is next and the recommendations are at the end.

No official server. An official command line, and community servers
An MCP server, for anyone who arrived by search engine, is the thing that lets an AI app call a program's functions. If a notes app has one, your assistant can read and write your notes. If it does not, you are the integration, with copy and paste.
🏠 Hosted or on your machine
This column decides more than the others put together.
A hosted server lives at an address on the internet. You add that address to Claude.ai or ChatGPT, sign in once in a browser, and it works from your laptop, your phone and a coding agent alike. Notion's is https://mcp.notion.com/mcp, Evernote's is https://mcp.evernote.com/mcp, Craft's is https://mcp.craft.do/my/mcp, and mine is https://sumibako.com/api/mcp. The cost is that your notes are already on somebody's server, which for these four apps they were anyway.
A local server runs on your computer and talks to an app on the same computer. Your notes never leave the machine to reach it, which is the whole appeal. The cost is that it only works from agents running on that machine, with the app open. Claude on your phone cannot reach a server on your laptop.
Neither is better. They answer different worries.
🔎 Notes on each
Notion has the strongest server here and it is not close. Its docs describe a hosted server with a browser sign-in, and the tool list runs to more than thirty: pages, databases, views, comments, even its own agents. The older open-source server "is no longer actively maintained". What none of them does is publish. The API's update endpoint has no sharing parameter and public_url is a field you can read but not set, so an agent can write the page and a person still has to click Share.
Obsidian has no MCP server of its own, and needs one less than anyone, because a vault is a folder of plain files and every coding agent can already write a file. Since version 1.12 there is also an official command line, which "requires the Obsidian app to be running". It includes publish:add, so an agent with a shell can put a note on the web, provided you pay for Obsidian Publish at $8 a site per month, billed annually. The community has written many MCP servers on top of all this. They vary.
Apple Notes has no server from Apple. The best maintained community one I found is apple-notes-mcp, MIT licensed, macOS only, which "runs locally on your Mac and talks to Notes through AppleScript". It can delete, which moves the note to Recently Deleted rather than into the void.
Evernote is arriving. Its MCP page says "Now in beta" and promises that clients can "read, search, and create notes". Its own Claude guide still says the server is "currently in development" and offers a waitlist, and adds that Claude can read your notes "but not change them". Two pages, two tenses. I would wait for them to agree.
Craft runs a hosted server with a browser sign-in where you choose which space to connect, and its help centre says an agent can "create, update, and delete documents". I found nothing about share links through the connection, in either direction.
Reflect added editing on 28 April 2026: its announcement lists adding, editing and deleting content from Claude Code, Cursor and Codex. The server is switched on in the desktop app's settings and listens on your own machine, per Reflect Academy, where it is labelled a beta.
Inkdropdocuments its server plainly: it connects to a local HTTP server in the desktop app and can "search, read, create and update your notes, notebooks and tags".
Sumibako, mine, has six tools against Notion's thirty-odd: write a page, edit part of one, read, search, publish, and report the plan's limits. There is no delete tool, on purpose. It can publish a page and return a link anyone can open, but only a page it wrote itself, and it cannot make any page visible to a search engine. There are no databases, no comments and no views. It is a notes app that agents can file into, not a workspace. The full list is on the agents page.
⚠️WARNING
Whatever you connect, read its tool list before you press Allow, and look for the word delete. Several of the eight above can delete. I wrote up what a connector can and cannot do to your data separately.
🧭 Which one, then
If you
Use
Already live in Notion, or need databases
Notion. Nothing else here is close on breadth
Want your notes to stay on your own disk
Obsidian, with an agent that writes files
Use Apple Notes and only work on a Mac
The community server, with the delete tool set to ask first
Want the agent to hand you a link you can send to someone
Sumibako, or Obsidian with Publish
Are on Evernote
Wait a month and read both of its pages again
The honest summary is that nearly every notes app can now be written to, and that stopped being a reason to choose one. What still differs is where the server runs, whether it can delete, and whether anything the agent writes can leave the app with an address. Pick on those.

Is there a web version of Obsidian? No, and five ways around it
Obsidian has no web version. Five ways to reach a vault from a browser anyway, from GitHub's free editor to the real app on a server, and what each costs.
