Remove the remaining shell glue from the canonical CLI workspace flows so users can hand off IDs and host-authored text files directly. Add --id-only on workspace create and shell open, plus --text-file and --patch-file for workspace file write and patch apply, while keeping the underlying SDK, MCP, and backend behavior unchanged. Update the top walkthroughs, contract docs, roadmap status, and use-case smoke runner to use the new shortcuts, and verify the milestone with uv lock, make check, make dist-check, focused CLI tests, and a real guest-backed smoke for create, file write, patch apply, and shell open/read.

# Public Contract
|
|
|
|
This document defines the stable public interface for `pyro-mcp` `3.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`
|
|
|
|
Stable product framing:
|
|
|
|
- `pyro run` is the stable one-shot entrypoint.
|
|
- `pyro workspace ...` is the stable persistent workspace contract.
|
|
|
|
## CLI Contract
|
|
|
|

|
|

|
|
|
|
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 workspace create` auto-starts a persistent workspace.
|
|
- `pyro workspace create --seed-path PATH` seeds `/workspace` from a host directory or a local `.tar` / `.tar.gz` / `.tgz` archive before the workspace is returned.
|
|
- `pyro workspace create --id-only` prints only the new `workspace_id` plus a trailing newline.
|
|
- `pyro workspace create --name NAME --label KEY=VALUE` attaches human-oriented discovery metadata without changing the stable `workspace_id`.
|
|
- `pyro workspace create --network-policy {off,egress,egress+published-ports}` controls workspace guest networking and whether services may publish localhost ports.
|
|
- `pyro mcp serve --profile {vm-run,workspace-core,workspace-full}` narrows the model-facing MCP surface without changing runtime behavior.
|
|
- `pyro workspace create --secret NAME=VALUE` and `--secret-file NAME=PATH` persist guest-only UTF-8 secrets outside `/workspace`.
|
|
- `pyro workspace list` returns persisted workspaces sorted by most recent `last_activity_at`.
|
|
- `pyro workspace sync push WORKSPACE_ID SOURCE_PATH [--dest WORKSPACE_PATH]` imports later host-side directory or archive content into a started workspace.
|
|
- `pyro workspace stop WORKSPACE_ID` stops one persistent workspace without deleting its `/workspace`, snapshots, or command history.
|
|
- `pyro workspace start WORKSPACE_ID` restarts one stopped workspace without resetting `/workspace`.
|
|
- `pyro workspace file list WORKSPACE_ID [PATH] [--recursive]` returns metadata for one live path under `/workspace`.
|
|
- `pyro workspace file read WORKSPACE_ID PATH [--max-bytes N]` reads one regular text file under `/workspace`.
|
|
- `pyro workspace file write WORKSPACE_ID PATH --text TEXT` and `--text-file PATH` create or replace one regular text file under `/workspace`, creating missing parent directories automatically.
|
|
- `pyro workspace export WORKSPACE_ID PATH --output HOST_PATH` exports one file or directory from `/workspace` back to the host.
|
|
- `pyro workspace disk export WORKSPACE_ID --output HOST_PATH` copies the stopped guest-backed workspace rootfs as raw ext4 to the host.
|
|
- `pyro workspace disk list WORKSPACE_ID [PATH] [--recursive]` inspects a stopped guest-backed workspace rootfs offline without booting the guest.
|
|
- `pyro workspace disk read WORKSPACE_ID PATH [--max-bytes N]` reads one regular file from a stopped guest-backed workspace rootfs offline.
|
|
- `pyro workspace disk *` requires `state=stopped` and a guest-backed workspace; it fails on `host_compat`.
|
|
- `pyro workspace diff WORKSPACE_ID` compares the current `/workspace` tree to the immutable create-time baseline.
|
|
- `pyro workspace snapshot *` manages explicit named snapshots in addition to the implicit `baseline`.
|
|
- `pyro workspace reset WORKSPACE_ID [--snapshot SNAPSHOT_NAME|baseline]` recreates the full sandbox and restores `/workspace` from the chosen snapshot.
|
|
- `pyro workspace service *` manages long-running named services inside one started workspace with typed readiness probes.
|
|
- `pyro workspace service start --publish GUEST_PORT` or `--publish HOST_PORT:GUEST_PORT` publishes one guest TCP port to `127.0.0.1` on the host.
|
|
- `pyro workspace exec --secret-env SECRET_NAME[=ENV_VAR]` maps one persisted secret into one exec call.
|
|
- `pyro workspace service start --secret-env SECRET_NAME[=ENV_VAR]` maps one persisted secret into one service start call.
|
|
- `pyro workspace exec` runs in the persistent `/workspace` for that workspace and does not auto-clean.
|
|
- `pyro workspace patch apply WORKSPACE_ID --patch TEXT` and `--patch-file PATH` apply one unified text patch with add/modify/delete operations under `/workspace`.
|
|
- `pyro workspace shell open --id-only` prints only the new `shell_id` plus a trailing newline.
|
|
- `pyro workspace shell open --secret-env SECRET_NAME[=ENV_VAR]` maps one persisted secret into the opened shell environment.
|
|
- `pyro workspace shell *` manages persistent PTY sessions inside a started workspace.
|
|
- `pyro workspace shell read --plain --wait-for-idle-ms 300` is the recommended chat-facing read mode; raw shell reads remain available without `--plain`.
|
|
- `pyro workspace logs` returns persisted command history for that workspace until `pyro workspace delete`.
|
|
- `pyro workspace update` changes only discovery metadata such as `name` and key/value `labels`.
|
|
- Workspace create/status results expose `workspace_seed` metadata describing how `/workspace` was initialized.
|
|
- Workspace create/status/reset/update results expose `name`, `labels`, and `last_activity_at`.
|
|
- Workspace create/status/reset results expose `network_policy`.
|
|
- Workspace create/status/reset results expose `reset_count` and `last_reset_at`.
|
|
- Workspace create/status/reset results expose safe `secrets` metadata with each secret name and source kind, but never the secret values.
|
|
- `pyro workspace status` includes aggregate `service_count` and `running_service_count` fields.
|
|
- `pyro workspace list` returns one summary row per persisted workspace with `workspace_id`, `name`, `labels`, `environment`, `state`, `created_at`, `last_activity_at`, `expires_at`, `command_count`, `service_count`, and `running_service_count`.
|
|
- `pyro workspace service start`, `pyro workspace service list`, and `pyro workspace service status` expose published-port metadata when present.

- `workspace_start` restarts one stopped workspace without resetting `/workspace`.
|
|
- `workspace_file_list`, `workspace_file_read`, and `workspace_file_write` provide structured live `/workspace` inspection and text edits without shell quoting.
|
|
- `workspace_export` exports one file or directory from `/workspace` to an explicit host path.
|
|
- `workspace_patch_apply` applies unified text patches for add/modify/delete operations under `/workspace`.
|
|
- `workspace_disk_export` copies the stopped guest-backed workspace rootfs as raw ext4 to an explicit host path.
|
|
- `workspace_disk_list` inspects a stopped guest-backed workspace rootfs offline without booting the guest.
|
|
- `workspace_disk_read` reads one regular file from a stopped guest-backed workspace rootfs offline.
|
|
- stopped-workspace disk tools require `state=stopped` and a guest-backed workspace; they fail on `host_compat`.
|
|
- `workspace_diff` compares the current `/workspace` tree to the immutable create-time baseline.
|
|
- `snapshot_create`, `snapshot_list`, and `snapshot_delete` manage explicit named snapshots in addition to the implicit `baseline`.
|
|
- `workspace_reset` recreates the full sandbox and restores `/workspace` from `baseline` or one named snapshot.
|
|
- `service_start`, `service_list`, `service_status`, `service_logs`, and `service_stop` manage persistent named services inside a started workspace.
|
|
- `service_start` accepts optional `published_ports` to expose guest TCP ports on `127.0.0.1` when the workspace network policy is `egress+published-ports`.
|
|
- `vm_exec` runs one command and auto-cleans that VM after the exec completes.
|
|
- `workspace_exec` accepts optional `secret_env` mappings for one exec call and leaves the workspace alive.
|
|
- `workspace_update` changes only discovery metadata such as `name` and key/value `labels`.
|
|
- `service_start` accepts optional `secret_env` mappings for one service start call.
|
|
- `shell_open` accepts optional `secret_env` mappings for the opened shell session.
|
|
- `shell_open`, `shell_read`, `shell_write`, `shell_signal`, and `shell_close` manage persistent PTY shells inside a started workspace.

## 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.
