About Jetpost MCP server
Collaborating on shared notes with teammates and AI agents is what Jetpost enables through a centralized inbox. Developers using Claude Code, Cursor, or Gemini CLI can create, edit, and organize notes that are immediately visible to others. The system allows agents to contribute to discussions, add pages, or append content to existing notes, with every modification clearly marked as being made by the specific agent involved.
Setting up the server involves using OAuth 2.1 with PKCE, meaning you sign in via a browser rather than managing manual API keys. The hosted MCP server provides a wide range of tools including create_note, search_notes, and edit_note. It also includes a specialized jetpost-share skill that allows you to distribute finished work to teammates or via email to individuals who do not use the platform. For visual content, the upload_image tool supports PNG, JPEG, GIF, and WebP files up to 20 MB by providing a signed upload address for direct transfer.
What you can do with it
- 1Collaborative note creationAsk your AI agent to draft a new note and share it with your team members.
- 2Iterative agent editingHave an AI agent modify specific parts of a note or add new pages to a document.
- 3External work distributionSend a completed note to someone outside of your organization using their email address.

README
View on GitHubJetpost plugin
Build on each other's ideas. Tell your agent "make a note." Your team, and their agents, can pick it up from there.
Jetpost is an inbox of notes for people and their agents. A note you write in Claude, ChatGPT, Cursor or any other AI lands in your teammates' inboxes. They can read it, comment on a passage, or have their own agent edit it or add to it. Every change an agent makes is marked as the agent's.
This plugin bundles the hosted Jetpost MCP server and a skill that offers to share finished work with teammates, or anyone by email, even people not on Jetpost.
Install
Claude (Claude Code and Cowork)
/plugin marketplace add send-co/jetpost-plugin
/plugin install jetpost@jetpost
Cursor
Install Jetpost from the Cursor marketplace.
Gemini CLI
gemini extensions install https://github.com/send-co/jetpost-plugin
Or point any MCP client at the server directly:
https://www.jetpost.com/mcp
Authentication
Jetpost uses OAuth 2.1 with PKCE. There's no API key to copy.
- Endpoint:
https://www.jetpost.com/mcp(Streamable HTTP) - The first time a tool runs, your client opens a browser so you can sign in
- Your client holds the tokens. This repository never sees them.

upload_image |
Add an image from your computer to a note. Returns a signed upload address and headers; your agent sends the file from your shell with one fixed curl -X PUT step written in the tool description. PNG, JPEG, GIF or WebP, up to 20 MB; the address expires in 15 minutes. Without a shell, your agent asks you to paste the image into the note in the app instead. |
What it sends and fetches
The plugin talks to https://www.jetpost.com. It sends what you ask your
agent to write (note text, pages, comments and the people to share with) and
fetches the notes you can read. The one exception is an image upload: the file
goes from your shell straight to Jetpost's image storage, Vercel Blob
(https://vercel.com/api/blob), using the one-time address upload_image
returns. Images are read back through jetpost.com. It sends nothing to anyone
else.
Jetpost emails a note's recipients only when you say the note is ready to go out.
