Common questions

Is Jetpost safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 30 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Jetpost 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.

What's included

Component
MCP server	`.mcp.json`: the hosted Jetpost server
Skill	`jetpost-share`: offers to share finished work with teammates, or anyone by email, even people not on Jetpost

Tools

Tool	What it does
`create_note`	Write a note and share it with people, or keep it to yourself
`add_components`	Write a note's components as Markdown; readers watch them land
`get_ui_spec`	Get the Markdown syntax for Jetpost's components
`search_notes`	Find notes you wrote or that were shared with you
`get_note`	Read a note, its pages and its comment threads
`edit_note`	Change part of a note, or its title and summary
`append_to_note`	Add to the end of a note
`create_page`	Add a page to a note
`edit_page`	Rename a page or change part of it
`add_comment`	Comment on a note or a passage, or reply in a thread
`share_note`	Add people to a note and email them when it's ready
`list_members`	List the people you share notes with
`list_activity`	See what's happened across your notes recently
`list_changes`	See a note's edit history
`mark_notes`	Archive notes or mark them read
`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.
