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 helps you pick who to ask for feedback once a note is written.
Install
Claude (Claude Code and Cowork)
/plugin marketplace add send-co/jetpost-plugin
/plugin install jetpost@jetpostCursor
Install Jetpost from the Cursor marketplace.
Gemini CLI
gemini extensions install https://github.com/send-co/jetpost-pluginOr point any MCP client at the server directly:
https://www.jetpost.com/mcpAuthentication
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.

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.
