# pyro-mcp

`pyro-mcp` is an MCP-compatible tool package for running ephemeral development environments with a VM lifecycle API.

## v0.1.0 Capabilities

- Split lifecycle tools for coding agents: `vm_list_profiles`, `vm_create`, `vm_start`, `vm_exec`, `vm_stop`, `vm_delete`, `vm_status`, `vm_reap_expired`.
- Standard environment profiles:
- `debian-base`: minimal Debian shell/core Unix tools.
- `debian-git`: Debian base with Git preinstalled.
- `debian-build`: Debian Git profile with common build tooling.
- Explicit sizing contract for agents (`vcpu_count`, `mem_mib`) with guardrails.
- Strict ephemerality for command execution (`vm_exec` auto-deletes VM on completion).
- Ollama demo that asks an LLM to run `git --version` through lifecycle tools.

## Runtime

The package includes a bundled Linux x86_64 runtime payload:
- Firecracker binary
- Jailer binary
- Profile artifacts for `debian-base`, `debian-git`, and `debian-build`

No system Firecracker installation is required for basic usage.

Host requirements still apply:
- Linux host
- `/dev/kvm` available for full virtualization mode

## Requirements

- Python 3.12+
- `uv`
- Optional for Ollama demo: local Ollama server and `llama:3.2-3b` model.

## Setup

```bash
make setup
```

## Run deterministic lifecycle demo

```bash
make demo
```

The demo creates a VM, starts it, runs `git --version`, and returns structured output.

## Runtime doctor

```bash
make doctor
```

This prints bundled runtime paths, profile availability, checksum validation status, and KVM host checks.

## Run Ollama lifecycle demo

```bash
ollama serve
ollama pull llama:3.2-3b
make ollama-demo
```

Defaults are configured in `Makefile`.
The demo streams lifecycle progress logs and ends with a short text summary.

## Run MCP server

```bash
make run-server
```

## Quality checks

```bash
make check
```

Includes `ruff`, `mypy`, and `pytest` with coverage threshold.

## Pre-commit

```bash
make install-hooks
```

Hooks execute the same lint/type/test gates.
