Wire a fifth pull hook so peer messages also surface between todo items, not only at user prompts and subagent stops. While here, extend the manual `install-hook` CLI so it patches the full plugin hook set (SessionStart/UserPromptSubmit/SubagentStop/TaskCompleted/ SessionEnd) instead of only UserPromptSubmit, mirroring what the plugin's hooks.json registers. Mailbox name is auto-derived from stdin, so --name is no longer required. Also corrects stale docs that claimed SessionStart auto-bootstraps the watcher — push delivery has been opt-in since the mailbox-collaborate skill landed.

# @kuns/claude-mailbox
|
||
|
||
Standalone MCP mail server that lets parallel Claude sessions coordinate with each other.
|
||
|
||
## Install
|
||
|
||
One-time per machine:
|
||
|
||
```sh
|
||
npm config set @kuns:registry=https://git.kuns.dev/api/packages/releases/npm/
|
||
npm install -g @kuns/claude-mailbox
|
||
```
|
||
|
||
Then:
|
||
|
||
```sh
|
||
claude-mailbox install-autostart # registers per-OS autostart, no admin needed by default
|
||
```
|
||
|
||
See the [repository README](https://git.kuns.dev/releases/ClaudeMailbox/src/branch/main/README.md) for the full architecture, MCP tool reference, and `.mcp.json` snippet.
|
||
|
||
## Claude Code hooks (auto-check inbox)
|
||
|
||
Register the full plugin-equivalent hook set so Claude pulls pending mailbox messages at every natural sync point:
|
||
|
||
```sh
|
||
claude-mailbox install-hook # patches ~/.claude/settings.json
|
||
claude-mailbox install-hook --project # patches <cwd>/.claude/settings.json
|
||
claude-mailbox uninstall-hook # remove again
|
||
```
|
||
|
||
This installs five hooks:
|
||
|
||
| Event | Command | When it fires |
|
||
|---|---|---|
|
||
| `SessionStart` | `session-announce` | Announces this session's mailbox identity + active peers. |
|
||
| `UserPromptSubmit` | `check --hook` | Before each user prompt. |
|
||
| `SubagentStop` | `check --hook` | When a subagent finishes. |
|
||
| `TaskCompleted` | `check --hook` | When Claude marks a `TaskCreate` task completed — gives mid-run sync points. |
|
||
| `SessionEnd` | `session-end` | Cleans up the auto-derived mailbox if empty. |
|
||
|
||
The mailbox name is auto-derived from the session-id stdin payload — no `--name` required. Install is idempotent and only touches our own commands; other hooks and settings are preserved.
|
||
|
||
`check --hook`:
|
||
|
||
- prints unread messages in a Claude-friendly format,
|
||
- silently exits 0 if the inbox is empty or the daemon is unreachable (no context noise),
|
||
- marks the messages delivered so they aren't injected again next prompt.
|
||
|
||
Cost: one local HTTP round-trip plus Node coldstart per fire (~100ms on Windows).
|
||
|
||
## Push delivery (watch)
|
||
|
||
For long-running autonomous sessions, run the watcher as a background bash task so peer messages surface immediately via `BashOutput`:
|
||
|
||
```sh
|
||
claude-mailbox watch --block --name <mailbox>
|
||
```
|
||
|
||
Exit codes: `0` delivered or renamed, `1` error, `2` daemon unreachable, `3` timeout. See the [repository README](https://git.kuns.dev/releases/ClaudeMailbox/src/branch/main/README.md#push-delivery-watch) for the full contract.
|
||
|
||
## Troubleshooting
|
||
|
||
`npm install` returns `401 Unauthorized`
|
||
: The Gitea registry usually serves the `releases` scope publicly, but if your instance requires auth you'll need a read token:
|
||
|
||
```sh
|
||
npm config set //git.kuns.dev/api/packages/releases/npm/:_authToken=<token>
|
||
```
|
||
|
||
`Cannot find module 'node:sqlite'` or similar
|
||
: claude-mailbox uses Node's built-in `node:sqlite`, stable since Node 24. On Node 22.5–23.x it works only with `--experimental-sqlite`. Upgrade to Node 24 LTS or newer: `nvm install 24 && nvm use 24` (or `winget install OpenJS.NodeJS.LTS` on Windows).
