Install and start

The daemon is the same harness the cloud runs: the memory and the modules, in one binary called pcx. Run it on your laptop for a memory that stays on your computer, or on a server for your team.

Install

Homebrew

brew install julymetodiev/tap/post-cortex

macOS and Linux.

Release binary

curl -L https://github.com/julymetodiev/post-cortex/releases/latest/download/pcx-aarch64-apple-darwin \
  -o /usr/local/bin/pcx && chmod +x /usr/local/bin/pcx

Other platforms are on the releases page.

From source

cargo install post-cortex-daemon --features surrealdb-storage

Rust 1.95 or newer.

Start

1. Write a config file to start from (optional):

   pcx init

   It creates ~/.post-cortex/daemon.toml. Without one, the defaults below apply.

2. Start the daemon:

   pcx start

3. Check it:

   pcx status
   curl http://127.0.0.1:3737/health

4. Point your agent at it. For Claude Code, set the plugin’s url to http://127.0.0.1:3737; for the other clients, pcx setup --self-hosted. See Claude Code and other agents.

Default	Value
Address	127.0.0.1 (this computer only)
Port	3737
Data	~/.post-cortex/data
MCP endpoint	http://127.0.0.1:3737/mcp

Stop it with pcx stop, or Ctrl+C in its terminal.

Note

Plain pcx, with no command, is a stdio MCP server for clients that only speak stdio: it starts the daemon if it is not running and forwards to it.

Next

• Reach it from other machines, set a token, choose the storage: Configure.
• Join it to your organization, so the app and your team reach it from anywhere: Connecting a daemon.
• Turn on the board, the shell, git and the other modules: Configure, modules.
