Batuta Mcp

Retired

Claude Code now does this itself. Splitting work across isolated worktrees so parallel agents do not collide is built in, which is what this existed to provide.

The repository is archived and read-only. It still works — nothing was removed from npm, and the last published version keeps installing — but it will not be maintained, and it does not need to be. If you want the idea rather than the package, the whole design is in docs/ and the licence lets you take it.

Why

Running several coding agents in parallel is fast — until two of them edit the same file and silently clobber each other's work. The fix isn't live coordination; it's separation: give each agent a set of files that don't overlap, and the conflict can't happen by design.

batuta-mcp is the brain that does that split. You hand it a brain dump; it returns plans with disjoint file boundaries, and scaffolds an isolated git worktree for each one.

How it works

It's a stateless MCP server (stdio). No database, no daemon, no web UI — just three tools that compose:

1. Decompose a brain dump into 2–5 plans whose fileBoundaries don't overlap (auto-corrects once if they do).
2. Check that the boundaries are truly disjoint.
3. Scaffold a git worktree per plan, returning a ready-to-paste prompt for each — open them in separate terminals/tabs and let one agent work each, conflict-free.

The "muscle" (running the agents, the terminals) stays in your editor; batuta-mcp is just the planning brain.

Features

• 🧠 Disjoint decomposition — plans are generated so no file appears in two plans.
• ♻️ Auto-correction — if the model returns overlapping boundaries, it retries once to separate them.
• 🌳 Worktree scaffolding — one isolated git worktree per plan, with a ready-to-paste prompt.
• 🔒 Safe by design — pre-flight checks (valid git repo, no overlaps, no path traversal) before touching disk; dryRun previews without writing.
• 🪶 Stateless — nothing persisted; uses your logged-in claude CLI (no API key needed).

Requirements

• Bun 1.3+
• git 2.x (for scaffold_worktrees)
• The claude CLI, logged in (for decompose_into_plans)
• Claude Code or any MCP client

Installation

From npm — nothing to clone:

claude mcp add batuta -- bunx --bun @vorluno/batuta-mcp

From source — if you want to change it:

git clone https://github.com/vorluno/batuta-mcp.gitcd batuta-mcpbun installclaude mcp add batuta -- bun run /absolute/path/to/batuta-mcp/src/index.ts

Configuration

Any MCP client works. The mcpServers entry:

{  "mcpServers": {    "batuta": {      "command": "bun",      "args": ["run", "/absolute/path/to/batuta-mcp/src/index.ts"]    }  }}

For Claude Code, claude mcp add (above) writes this for you. For Warp or Cursor, paste the snippet into their MCP settings.

Tools

Typical flow

1. decompose_into_plans → plans with disjoint boundaries.
2. check_boundary_overlaps → confirm ok: true (or adjust).
3. scaffold_worktrees → creates the worktrees; open each in its own terminal/tab and paste its suggestedPrompt.

Development

Built test-first across 10 TDD tasks with per-task and whole-branch review.
