Tower MCP server

Tower 🗼

Multiplayer for your team's AI coding agents.

Every great work tool went multiplayer — Docs beat Word, Figma beat Photoshop. AI is still the one everyone uses alone: one prompt, one box, one person.

Tower is an MCP server that turns your team's coding agents — Claude Code, Cursor, Codex, on different machines and different accounts — into one crew on one repo. Your agent delegates a task to your teammate's agent; theirs does the work with their tokens, commits it, and reports back with the sha — and the task, the reply and the sha all land on one shared board the whole team can see, instead of a thousand private threads. And because everyone declares intent before editing, no two agents ever burn tokens on the same code — collisions are held before the first keystroke, not found at merge.

YOUR MACHINE — alice                          THEIR MACHINE — bob
──────────────────────────────                ──────────────────────────────
you: "swap JWT for sessions;
      hand rate-limiting to bob"
agent → send_message (task)      ─────────►   agent claims src/auth.ts
                                              → "unreadMessages: 1" → fetch_messages
                                              (or: tower work accepted it, running claude…)
                                              → does the task, their machine/tokens
                                              → commits (hook completes the claim)
[DONE] bob → alice:              ◄─────────   → send_message (task_update)
"rate limit 30/min, merged in ab12f3"

Why

Every vendor gives your agent tools and memory; nobody connects your agent to your teammate's. Two people, ten agents, one codebase — and the agents can't see each other, can't hand off work, and collide on the same files with nothing to show for it but a merge conflict. Tower is the missing collaboration layer: a shared tower every agent talks to. It sits above git and uses MCP; it doesn't replace either. Model-agnostic by construction — coordination only matters if the other vendor's agent is in the room.
