Install
Pick the AI app you use, then copy the settings.
Before you install
- Basic checks: 1 of 1 passed
- Runs on your computer with your user’s permissions (files, network, apps).
- You fill in yourself:
FLEETPOST_CONFIG,FLEETPOST_HOME
You need
- PyPIPython’s uv installed (for the uvx command)
Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json
{
"mcpServers": {
"fleetpost": {
"command": "uvx",
"args": [
"fleetpost-mcp"
],
"env": {
"FLEETPOST_CONFIG": "your-value",
"FLEETPOST_HOME": "your-value"
}
}
}
}Run this in your terminal
claude mcp add fleetpost --env FLEETPOST_CONFIG=your-value --env FLEETPOST_HOME=your-value -- uvx fleetpost-mcpFill in the empty values before running it.
Or copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

],
"env": {
"FLEETPOST_CONFIG": "your-value",
"FLEETPOST_HOME": "your-value"
}
}
}
}Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.
Or copy the settings yourself

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.
Your choice stays on this device in a cookie; no account needed.
Values you fill in
FLEETPOST_CONFIGenvPath to your Fleetpost config.env. Optional if you start the server from the checkout that contains it.FLEETPOST_HOMEenvPath to the Fleetpost checkout, if config.env was copied away from it. Needed by fleet_sync and fleet_handle.
These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions
Is Fleetpost 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 on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.
What can I use instead?

README from the maker

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.
fleetpost-mcp
Give your agent the fleet's mailbox. An MCP server for Fleetpost — offline-tolerant, server-less coordination between machines over any rclone remote.
Your agent can ask what the other machines can do, hand one of them a task, and work through its own inbox — without a server, a daemon, or every machine being online at once. A machine that is off picks up its mail on its next cycle.
Tools
| Tool | What it does |
|---|---|
fleet_status | What is waiting: unhandled requests, protocol changes, who is known, last cycle |
fleet_capabilities | What each machine in the fleet can do |
fleet_read_request | Read one request from this machine's inbox |
fleet_send_request | Ask another machine to do something — drops a request in its inbox |
fleet_handle | Mark a request done; moves it to inbox/handled/ |
fleet_sync | Run one coordination cycle now |
Only fleet_send_request and fleet_sync touch the remote. Everything else reads files the sync already pulled, so status is instant and works with no network at all.
Setup
You need a working Fleetpost checkout with a filled-in config.env — see the main README. The MCP server reads that same file; it introduces no configuration of its own.
{"mcpServers": { "fleetpost": { "command": "uvx", "args": ["fleetpost-mcp"], "env": { "FLEETPOST_CONFIG": "/path/to/fleetpost/config.env" } } } }
FLEETPOST_CONFIG can be omitted if the server starts in the directory holding config.env. If you copied the config away from the checkout, also set FLEETPOST_HOME to the checkout — fleet_sync and fleet_handle run the repo's own scripts.
Then ask your agent:
Anything waiting for me? — and if the build box can sign, ask it to sign the release.
What it will not do
The protocol's rules are enforced here, not just documented:
- Writes only into another machine's inbox, at the top level. Never into
handled/, never into anyone's descriptors. That is what keeps concurrent writes safe. - `fleet_handle` only tidies your own inbox — the owner is the only one allowed to.
- A request must be complete to be sent. What is wanted, what "done" means, and an expiry are required arguments; a malformed request cannot be created.
- Ask for actions, not access. If a job needs a credential you lack, the machine that has it does the work and returns the result. Secrets never travel.
There is no server, no database, and no daemon of our own — the transport stays a folder on an rclone remote, and this server only reads and writes files in it.
