| name | mk0r-cli |
| description | Use when the user says "mk0r", "appmaker CLI", "open a VM", "run something in the sandbox", "talk to the VM agent", "spin up an E2B sandbox", or "chat with appmaker from CLI." Wraps the `mk0r` CLI to list projects, exec commands inside their E2B sandboxes, stream chat with the VM agent (same `/api/chat` the web UI uses), toggle SOAX residential IP, manage schedules, and copy files. Supports a sticky default project via `mk0r projects use`. |
mk0r CLI Skill
The mk0r CLI is the programmatic entry point to appmaker (mk0r.com / staging.mk0r.com). Each project = one E2B sandbox with a persistent Chromium on CDP :9222 + Playwright MCP on :3001 + an ACP bridge on :3002, all routed through a SOAX residential proxy on :3003 when enabled.
Setup (one-time per shell)
1. Stash the API key in macOS keychain
The user mints a key at https://staging.mk0r.com/account/api-keys (or https://mk0r.com/account/api-keys for prod). Each key starts with mk0r_. Save it under a canonical name so this skill (and future scripts) can find it without re-prompting:
security add-generic-password -U -a "$USER" \
-s "mk0r-api-key-staging" -w 'mk0r_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
security add-generic-password -U -a "$USER" \
-s "mk0r-api-key-prod" -w 'mk0r_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
To look it up later:
security find-generic-password -s "mk0r-api-key-staging" -w
2. Install / locate the CLI
The CLI lives in the appmaker repo (cli/ directory). To put mk0r on PATH:
cd ~/appmaker/cli && npm link
mk0r --help
If you don't want the global symlink, invoke directly:
node ~/appmaker/cli/bin/mk0r.js --help
3. Write the config file
KEY=$(security find-generic-password -s "mk0r-api-key-staging" -w)
mkdir -p ~/.config/mk0r
printf '{\n "host": "https://staging.mk0r.com",\n "apiKey": "%s"\n}' "$KEY" \
> ~/.config/mk0r/config.json
chmod 600 ~/.config/mk0r/config.json
For prod, swap staging.mk0r.com → mk0r.com. The CLI also honours MK0R_HOST, MK0R_API_KEY, and MK0R_PROJECT env vars; they override the file values.
Verify
mk0r whoami
mk0r projects ls
Pin a default project (highly recommended)
mk0r projects use <projectId>
mk0r projects current
mk0r projects use --clear
After pinning, mk0r exec, mk0r chat, mk0r session, mk0r cp, mk0r cat, mk0r runs, and mk0r schedule … all accept the projectId as optional and fall back to the default. You can also pass MK0R_PROJECT=<id> as a per-shell override.
Primary path: chat with the VM agent
mk0r chat is the canonical way to drive the VM. It hits /api/chat (same endpoint the web UI uses), streams the NDJSON response, and renders text deltas to stdout + tool calls (→ tool(args) / ✓ / ✗) to stderr.
mk0r chat "navigate to https://example.com and tell me the H1"
mk0r chat <projectId> "your prompt"
mk0r chat "your prompt" --quiet
mk0r chat "your prompt" --no-thinking
The agent has these tools: bash/terminal, file read/write, Playwright MCP (same Chromium that runs on :9222, proxied through SOAX). Browser actions automatically route through the residential exit.
Escape hatch: exec / cp / cat
When you want to bypass the agent and poke the sandbox directly:
mk0r exec -- "uname -a; whoami; ls /app"
RUN_ID=$(mk0r exec --async -- "bash /app/long-job.sh")
mk0r runs $RUN_ID --watch
mk0r cp ./local.txt :/tmp/remote.txt
mk0r cat :/tmp/remote.txt
Pass <projectId>:<path> to override the default for a single command.
Residential IP toggle (SOAX)
mk0r session info
mk0r session brd on --country us
mk0r session brd off
mk0r session brd status
State is persisted in Firestore on the session doc (useResidentialIp, residentialCountry). The system re-applies it on every sandbox pause/resume. SOAX rotates the exit IP every 5 minutes within a session (sessionlength-300), so consecutive reads of ipify.org will often differ; both will be residential, both will be in the requested country.
Schedules
mk0r schedule ls
mk0r schedule create --cron "*/20 * * * *" --command "./skill/run-cycle.sh" --tz America/Los_Angeles
mk0r schedule run <scheduleId>
mk0r schedule rm <scheduleId>
The orchestrator uses fire-and-forget exec when ACP_CALLBACK_BASE_URL is set on Cloud Run: the sandbox runs the command detached, POSTs back to /api/scheduled/finish when done. Tolerates 3h+ jobs even though Cloud Run's sync HTTP ceiling is 60 minutes.
Architecture notes (so the model doesn't re-derive)
- One Chromium per sandbox, launched with
--proxy-server=http://127.0.0.1:3003 --remote-debugging-port=9222. @playwright/mcp attaches via --cdp-endpoint http://127.0.0.1:9222, so MCP browser calls AND raw CDP both hit the same process. There is no second browser.
- Chat messages render client-side only today. The Firestore
app_sessions/{sessionKey} doc holds VM metadata, not chat turns. So mk0r chat streams go to the CLI; web UI streams go to that tab; neither sees the other's history. The agent itself remembers (ACP-level memory) — open the web UI and ask "what did we just do?" and it will recap.
- OAuth, not API key. Each sandbox writes the user's refreshing Claude OAuth token to
~/.claude/.credentials.json and explicitly does NOT set ANTHROPIC_API_KEY. Subprocesses (e.g. claude -p) inherit OAuth for free.
Common asks
| Ask | Command |
|---|
| "list my projects" | mk0r projects ls |
| "create a project named X" | mk0r projects create X |
| "open project X in the browser" | open -a "Google Chrome" "https://staging.mk0r.com/app/<id>" |
| "what egress IP am I going out from" | mk0r session brd status |
| "navigate the agent to URL X" | mk0r chat "navigate to X with playwright and report the title" |
| "run X in the VM" | mk0r chat "run X and tell me what happens" (primary) or mk0r exec -- X (escape hatch) |
| "did the long job finish?" | mk0r runs <runId> |
| "schedule X every 20 minutes" | mk0r schedule create --cron "*/20 * * * *" --command "X" |
Don'ts
- Don't
curl the raw /api/chat endpoint when mk0r chat already streams + renders properly.
- Don't put
--no-thinking / --quiet BEFORE the prompt. parseArgs will consume the next token as the flag's value and your prompt vanishes.
- Don't write API keys into source files. Always pull from keychain at runtime.
- Don't restart the sandbox by hand. Pause/resume is handled by appmaker on inactivity.
mk0r session brd on re-asserts the proxy config across resumes automatically.
