ATXP Git — Agent Repository Hosting

ATXP Git gives each agent a private namespace for Git repositories on code.storage. Agents can create repos, get authenticated clone/push URLs, and interact with them using standard Git commands. The MCP server handles provisioning and access control — all file operations happen through native Git.

Ephemeral Remote URLs

This is the most important concept to understand when using this tool.

Remote URLs returned by remote-url contain a time-limited JWT embedded directly in the URL. This means:

  1. URLs expire. The default TTL is 1 hour (3600 seconds). After expiry, any git clone, git push, git pull, or git fetch using that URL will fail with an authentication error.
  2. URLs are not persistent. Do not store remote URLs in config files, environment variables, or long-lived scripts expecting them to work indefinitely. They are single-use credentials with a short lifespan.
  3. Refresh when expired. When a git operation fails with an auth error, get a fresh URL and update the remote:
# Get a new writable URL
npx atxp@latest git remote-url my-project --writable

# Update the existing remote with the new URL
git remote set-url origin <new-url>

# Retry the operation
git push
  1. No separate credential setup needed. The URL embeds authentication — no git credential helper or SSH key configuration is required.
  2. Read vs. write URLs. Read-only URLs are free. Writable URLs cost $0.01 (this meters storage growth from pushes). Always request read-only unless you need to push.

Practical Workflow for Long-Running Tasks

If your task involves multiple git operations over time:

1. Get a writable URL at the start of your work session
2. Clone and make changes
3. Commit and push before the URL expires (within 1 hour)
4. If you need to push again later, get a fresh URL first

For tasks that may span multiple hours, request a new URL before each push rather than at the start. The --ttl flag can extend expiry up to the server maximum, but planning for refresh is more robust.

Security Model

  • Repos are private by default — only the owner can access them.
  • Public repos allow read-only access from other authenticated users via remote-url with writable: false.
  • Write access requires repo ownership. No collaborator model — repos are single-owner.
  • URLs contain credentials — treat remote-url output like a secret. Do not log, echo, or share writable URLs.
  • Soft-delete — deleted repos become immediately inaccessible but are permanently removed after 30 days.

Commands Reference

| Command | Cost | Description | |---------|------|-------------| | npx atxp@latest git create <repoName> | $0.50 | Create a new repository | | npx atxp@latest git list | Free | List your repositories | | npx atxp@latest git remote-url <repoName> | Free | Get a read-only authenticated URL | | npx atxp@latest git remote-url <repoName> --writable | $0.01 | Get a writable authenticated URL | | npx atxp@latest git delete <repoName> | Free | Soft-delete a repository | | npx atxp@latest git help | Free | Show help |

Options

| Option | Applies To | Description | |--------|-----------|-------------| | --visibility <private\|public> | create | Repository visibility (default: private) | | --default-branch <name> | create | Default branch name (default: main) | | --writable | remote-url | Request a push-capable URL ($0.01 instead of free) | | --ttl <seconds> | remote-url | URL expiry in seconds (default: 3600) | | --limit <n> | list | Max repos to return (default: 20, max: 100) | | --cursor <token> | list | Pagination cursor from a previous response |

Repo Naming

Repository names must be lowercase alphanumeric with hyphens and underscores only (e.g., my-project, agent_workspace).

Typical Agent Workflow

# 1. Create a repository ($0.50)
npx atxp@latest git create my-app

# 2. Get a writable URL ($0.01)
npx atxp@latest git remote-url my-app --writable
# Returns: https://t:eyJ...@atxp.code.storage/userid/my-app.git

# 3. Clone, work, push (standard git)
git clone <url>
cd my-app
# ... make changes ...
git add . && git commit -m "initial commit" && git push

# 4. Later — URL expired? Get a fresh one
npx atxp@latest git remote-url my-app --writable
git remote set-url origin <new-url>
git push

Error Responses

| Scenario | Error message | |----------|---------------| | Not authenticated | "ATXP authentication required" | | Repo doesn't exist (or private + not owner) | "Repository not found" | | Write to another user's repo | "Permission denied" | | Repo name already taken | "Repository already exists" | | Service unavailable | "Service temporarily unavailable. Please retry in a few seconds." | | Git ref conflict | "Conflict: ... Re-read the current state and retry." |

Visibility

| Mode | Owner | Other authenticated users | |------|-------|---------------------------| | Private | Full read/write | No access | | Public | Full read/write | Read-only (via remote-url with read-only default) |
