I built an MCP server that lets Claude publish the tools it builds and share them with your team
Claude Code is great at building small tools, but they usually stay stuck on localhost.
ShareBox is a self-hosted platform plus an MCP server. You ask "build a vacation tracker for my team and publish it on ShareBox": Claude reads the built-in guide (`sharebox_guide`), writes the tool, calls `sharebox_publish` and replies with an HTTPS link. Then "share it with anna@company.com" → `sharebox_share`, effective immediately.
The platform handles Google sign-in, per-tool storage and sandboxing, so the tool Claude writes never needs its own login or database: it just calls `sharebox.me()` and `sharebox.collection("vacations").add(...)`.
Setup:
npm i -g sharebox-cli
sharebox login your-instance.example.com
claude mcp add --scope user sharebox -- sharebox mcp
It's also in the official MCP registry as io.github.zalaso/sharebox.
Fully built with Claude Code itself. Self-hosted, AGPL: https://github.com/zalaso/sharebox
