Current persistent tasks started with an empty workspace, which blocked the first useful host-to-task workflow in the task roadmap. This change lets task creation start from a host directory or tar archive without changing the one-shot VM surfaces. Expose source_path on task create across the CLI, SDK, and MCP, add safe archive upload and extraction support for guest and host-compat backends, persist workspace_seed metadata, and patch the per-task rootfs with the bundled guest agent before boot so seeded guest tasks work without republishing environments. Also switch post--- command reconstruction to shlex.join() so documented sh -lc task examples preserve argument boundaries. Validation: - uv lock - UV_CACHE_DIR=.uv-cache uv run pytest --no-cov tests/test_vm_guest.py tests/test_vm_manager.py tests/test_cli.py tests/test_api.py tests/test_server.py tests/test_public_contract.py - UV_CACHE_DIR=.uv-cache make check - UV_CACHE_DIR=.uv-cache make dist-check - real guest-backed smoke: task create --source-path, task exec -- cat note.txt, task delete

# Public Contract
|
|
|
|
This document defines the supported public interface for `pyro-mcp` `2.x`.
|
|
|
|
## Package Identity
|
|
|
|
- Distribution name: `pyro-mcp`
|
|
- Public executable: `pyro`
|
|
- Public Python import: `from pyro_mcp import Pyro`
|
|
- Public package-level factory: `from pyro_mcp import create_server`
|
|
|
|
## CLI Contract
|
|
|
|
Top-level commands:
|
|
|
|
- `pyro env list`
|
|
- `pyro env pull`
|
|
- `pyro env inspect`
|
|
- `pyro env prune`
|
|
- `pyro mcp serve`
|
|
- `pyro run`
|
|
- `pyro task create`
|
|
- `pyro task exec`
|
|
- `pyro task status`
|
|
- `pyro task logs`
|
|
- `pyro task delete`
|
|
- `pyro doctor`
|
|
- `pyro demo`
|
|
- `pyro demo ollama`
|
|
|
|
Stable `pyro run` interface:
|
|
|
|
- positional environment name
|
|
- `--vcpu-count`
|
|
- `--mem-mib`
|
|
- `--timeout-seconds`
|
|
- `--ttl-seconds`
|
|
- `--network`
|
|
- `--allow-host-compat`
|
|
- `--json`
|
|
|
|
Behavioral guarantees:
|
|
|
|
- `pyro run <environment> -- <command>` defaults to `1 vCPU / 1024 MiB`.
|
|
- `pyro run` fails if guest boot or guest exec is unavailable unless `--allow-host-compat` is set.
|
|
- `pyro run`, `pyro env list`, `pyro env pull`, `pyro env inspect`, `pyro env prune`, and `pyro doctor` are human-readable by default and return structured JSON with `--json`.
|
|
- `pyro demo ollama` prints log lines plus a final summary line.
|
|
- `pyro task create` auto-starts a persistent workspace.
|
|
- `pyro task create --source-path PATH` seeds `/workspace` from a host directory or a local
|
|
`.tar` / `.tar.gz` / `.tgz` archive before the task is returned.
|
|
- `pyro task exec` runs in the persistent `/workspace` for that task and does not auto-clean.
|
|
- `pyro task logs` returns persisted command history for that task until `pyro task delete`.
|
|
- Task create/status results expose `workspace_seed` metadata describing how `/workspace` was
|
|
initialized.
|
|
|
|
## Python SDK Contract
|
|
|
|
Primary facade:
|
|

Stable public method names:
|
|
|

|
|
- `list_environments()`
|
|
- `pull_environment(environment)`
|
|
- `inspect_environment(environment)`
|
|
- `prune_environments()`
|
|
- `create_vm(...)`
|
|
- `create_task(...)`
|
|
- `start_vm(vm_id)`
|
|
- `exec_vm(vm_id, *, command, timeout_seconds=30)`

|
|
- `status_task(task_id)`
|
|
- `logs_task(task_id)`
|
|
- `network_info_vm(vm_id)`
|
|
- `reap_expired()`
|
|
- `run_in_vm(...)`
|
|
|
|
Behavioral defaults:
|
|
|
|
- `Pyro.create_vm(...)` and `Pyro.run_in_vm(...)` default to `vcpu_count=1` and `mem_mib=1024`.
|
|
- `Pyro.create_task(...)` defaults to `vcpu_count=1` and `mem_mib=1024`.
|
|
- `allow_host_compat` defaults to `False` on `create_vm(...)` and `run_in_vm(...)`.
|
|
- `allow_host_compat` defaults to `False` on `create_task(...)`.
|
|
- `Pyro.create_task(..., source_path=...)` seeds `/workspace` from a host directory or a local
|
|
`.tar` / `.tar.gz` / `.tgz` archive before the task is returned.
|
|
- `Pyro.exec_vm(...)` runs one command and auto-cleans that VM after the exec completes.
|
|
- `Pyro.exec_task(...)` runs one command in the persistent task workspace and leaves the task alive.
|
|
|
|
## MCP Contract
|
|
|
|
Primary tool:
|
|
|
|
- `vm_run`
|
|
|
|
Advanced lifecycle tools:
|
|
|
|
- `vm_list_environments`
|
|
- `vm_create`
|
|
- `vm_start`
|
|
- `vm_exec`
|
|
- `vm_stop`
|
|
- `vm_delete`
|
|
- `vm_status`
|
|
- `vm_network_info`
|
|
- `vm_reap_expired`
|
|
|
|
Task workspace tools:
|
|
|
|
- `task_create`
|
|
- `task_exec`
|
|
- `task_status`
|
|
- `task_logs`
|
|
- `task_delete`
|
|
|
|
Behavioral defaults:
|
|
|
|
- `vm_run` and `vm_create` default to `vcpu_count=1` and `mem_mib=1024`.
|
|
- `task_create` defaults to `vcpu_count=1` and `mem_mib=1024`.
|
|
- `vm_run` and `vm_create` expose `allow_host_compat`, which defaults to `false`.
|
|
- `task_create` exposes `allow_host_compat`, which defaults to `false`.
|
|
- `task_create` accepts optional `source_path` and seeds `/workspace` from a host directory or a
|
|
local `.tar` / `.tar.gz` / `.tgz` archive before the task is returned.
|
|
- `vm_exec` runs one command and auto-cleans that VM after the exec completes.
|
|
- `task_exec` runs one command in a persistent `/workspace` and leaves the task alive.
|
|
|
|
## Versioning Rule
|
|
|
|
- `pyro-mcp` uses SemVer.
|
|
- Environment names are stable identifiers in the shipped catalog.
|
|
- Changing a public command name, public flag, public method name, public MCP tool name, or required request field is a breaking change.
