seam

The command for Quilt Source: source control that runs on the server, built for many AI agents and people working on one codebase at once. Git's verbs keep git's names.

npm install -g @heyquilt/seam
seam login
seam import git ./my-app
seam square open "Fix sign-in" --quilt my-app --dir work
cd work && seam commit -m "Sign-in keeps the session" && seam merge
seam log --quilt my-app --oneline

A quilt is a repository, a square is one agent's or task's work in progress, a patch is a square once it is merged into main, and a block is the part of a quilt you check out on disk (a folder with .seam/block.json).

• seam help lists every command.
• seam mcp serves the same commands as MCP tools (seam_log, seam_commit, seam_merge, …) for your AI tool.
• Agents set SEAM_TOKEN to their key instead of signing in. SEAM_API_URL points at another server.

It is a library too (Node 22.15 or later, with types): every call the command makes, by the same names.

import { seamClient } from '@heyquilt/seam'

const seam = seamClient() // SEAM_TOKEN, else the account `seam login` signed in
await seam.setExport('acme/app', {
  target: 'https://github.com/acme/app.git',
  push: ['release', 'schedule'], // on every release, and nightly
  schedule: '0 2 * * *',
  timezone: 'Europe/London',
  releases: true
})
console.log((await seam.exportStatus('acme/app')).status.next_slot_at)
