Add explicit workspace secrets across the CLI, SDK, and MCP, with create-time secret definitions and per-call secret-to-env mapping for exec, shell open, and service start. Persist only safe secret metadata in workspace records, materialize secret files under /run/pyro-secrets, and redact secret values from exec output, shell reads, service logs, and surfaced errors. Fix the remaining real-guest shell gap by shipping bundled guest init alongside the guest agent and patching both into guest-backed workspace rootfs images before boot. The new init mounts devpts so PTY shells work on Firecracker guests, while reset continues to recreate the sandbox and re-materialize secrets from stored task-local secret material. Validation: uv lock; UV_CACHE_DIR=.uv-cache make check; UV_CACHE_DIR=.uv-cache make dist-check; and a real guest-backed Firecracker smoke covering workspace create with secrets, secret-backed exec, shell, service, reset, and 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 workspace create`
|
|
- `pyro workspace sync push`
|
|
- `pyro workspace exec`
|
|
- `pyro workspace export`
|
|
- `pyro workspace diff`
|
|
- `pyro workspace snapshot create`
|
|
- `pyro workspace snapshot list`
|
|
- `pyro workspace snapshot delete`
|
|
- `pyro workspace reset`
|
|
- `pyro workspace service start`
|
|
- `pyro workspace service list`
|
|
- `pyro workspace service status`
|
|
- `pyro workspace service logs`
|
|
- `pyro workspace service stop`
|
|
- `pyro workspace shell open`
|
|
- `pyro workspace shell read`
|
|
- `pyro workspace shell write`
|
|
- `pyro workspace shell signal`
|
|
- `pyro workspace shell close`
|
|
- `pyro workspace status`
|
|
- `pyro workspace logs`
|
|
- `pyro workspace 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 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 --secret NAME=VALUE` and `--secret-file NAME=PATH` persist guest-only UTF-8 secrets outside `/workspace`.
|
|
- `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 export WORKSPACE_ID PATH --output HOST_PATH` exports one file or directory from `/workspace` back to the host.
|
|
- `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 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 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 logs` returns persisted command history for that workspace until `pyro workspace delete`.
|
|
- Workspace create/status results expose `workspace_seed` metadata describing how `/workspace` was initialized.
|
|
- 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.

|
|
## 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.
