Crew Bus — Local AI agent teams on Mac + iPhone, built entirely on MCP

[WestCoastRJ]

Hey everyone — I'm Ryan, solo developer behind Crew Bus, a macOS + iOS app that runs coordinated AI agent teams locally on your Mac.

The whole thing is built on MCP. Here's what it does:

11 MCP tools let Claude (or any MCP client) orchestrate a crew of specialized agents running on your Mac:

• Crew Boss — task coordinator, delegates work across agents
• Guardian — security gatekeeper, approves/blocks skills and permissions
• Vault — encrypted memory and file storage
• Plus custom agents you create and organize into teams

How it works:
You say things like "ask Crew Boss to plan my week" or "what has Guardian flagged?" — and Claude uses MCP tools to coordinate your local agents through natural conversation.

Transport: stdio for Claude Desktop + Streamable HTTP with OAuth 2.1 via Cloudflare Workers relay for remote access

Privacy-first: All agent processing runs locally on your Mac. The relay is pass-through only — no data stored or logged.

What's shipping:

• Mac app (signed/notarized DMG) — live at crew-bus.dev
• iPhone companion app — just submitted to the App Store
• .mcpb desktop extension file — drag onto Claude Desktop to connect
• Open source: github.com/crew-bus/crew-bus

All 11 tools have safety annotations (readOnlyHint/destructiveHint). Privacy policy, 3 usage examples, manifest.json v0.3 — everything per the directory submission guide.

Would love feedback from the community. Happy to answer questions about the architecture or MCP integration.
