Make the docs and help text unapologetically teach as the product path for Claude Code, Codex, and OpenCode on Linux KVM.
Rewrite the README, install/first-run/integration guides, public contract, vision, and use-case docs around the zero-to-hero chat flow, and explicitly note that there are no users yet so breaking changes are acceptable while the interface is still being shaped.
Update package metadata, CLI help, and the docs/help expectation tests to match the new positioning. Validate the reframe with usage: pyro [-h] [--version] COMMAND ...
Validate the host and serve disposable MCP workspaces for chat-based coding agents on supported Linux x86_64 KVM hosts.
positional arguments:
COMMAND
env Inspect and manage curated environments.
mcp Run the MCP server.
run Run one command inside an ephemeral VM.
workspace Manage persistent workspaces.
doctor Inspect runtime and host diagnostics.
demo Run built-in demos.
options:
-h, --help show this help message and exit
--version show program's version number and exit
Suggested zero-to-hero path:
pyro doctor
pyro env list
pyro env pull debian:12
pyro run debian:12 -- git --version
pyro mcp serve
Connect a chat host after that:
claude mcp add pyro -- uvx --from pyro-mcp pyro mcp serve
codex mcp add pyro -- uvx --from pyro-mcp pyro mcp serve
If you want terminal-level visibility into the workspace model:
pyro workspace create debian:12 --seed-path ./repo --id-only
pyro workspace sync push WORKSPACE_ID ./changes
pyro workspace exec WORKSPACE_ID -- cat note.txt
pyro workspace diff WORKSPACE_ID
pyro workspace snapshot create WORKSPACE_ID checkpoint
pyro workspace reset WORKSPACE_ID --snapshot checkpoint
pyro workspace shell open WORKSPACE_ID --id-only
pyro workspace service start WORKSPACE_ID app --ready-file .ready -- sh -lc 'touch .ready && while true; do sleep 60; done'
pyro workspace export WORKSPACE_ID note.txt --output ./note.txt, usage: pyro mcp serve [-h] [--profile {vm-run,workspace-core,workspace-full}]
Expose pyro tools over stdio for an MCP client. Bare `pyro mcp serve` now starts `workspace-core`, the recommended first profile for most chat hosts.
options:
-h, --help show this help message and exit
--profile {vm-run,workspace-core,workspace-full}
Expose only one model-facing tool profile. `workspace-
core` is the default and recommended first profile for
most chat hosts; `workspace-full` is the larger opt-in
profile. (default: workspace-core)
Default and recommended first start:
pyro mcp serve
Profiles:
workspace-core: default for normal persistent chat editing
vm-run: smallest one-shot-only surface
workspace-full: larger opt-in surface for shells, services,
snapshots, secrets, network policy, and disk tools
Use --profile workspace-full only when the host truly needs those
extra workspace capabilities., and uv run ruff check .
All checks passed!

Chat Host Integrations
This page documents the intended product path for pyro-mcp:
- validate the host with the CLI
- run
pyro mcp serve - connect a chat host
- let the agent work inside disposable workspaces
pyro-mcp currently has no users. Expect breaking changes while this chat-host
path is still being shaped.
Use this page after you have already validated the host and guest execution through install.md or first-run.md.
Recommended Default
Bare pyro mcp serve starts workspace-core. That is the product path.
pyro mcp serve
Use --profile workspace-full only when the chat truly needs shells, services,
snapshots, secrets, network policy, or disk tools.
Claude Code
Package without install:
claude mcp add pyro -- uvx --from pyro-mcp pyro mcp serve
claude mcp list
Already installed:
claude mcp add pyro -- pyro mcp serve
claude mcp list
Reference:
Codex
Package without install:
codex mcp add pyro -- uvx --from pyro-mcp pyro mcp serve
codex mcp list
Already installed:
codex mcp add pyro -- pyro mcp serve
codex mcp list
Reference:
OpenCode
Use the local MCP config shape from:
Minimal opencode.json snippet:
{
"mcp": {
"pyro": {
"type": "local",
"enabled": true,
"command": ["uvx", "--from", "pyro-mcp", "pyro", "mcp", "serve"]
}
}
}
If pyro-mcp is already installed, replace uvx --from pyro-mcp pyro with
pyro in the same config shape.
Generic MCP Fallback
Use this only when the host expects a plain mcpServers JSON config and does
not already have a dedicated example in the repo:
Generic mcpServers shape:
{
"mcpServers": {
"pyro": {
"command": "uvx",
"args": ["--from", "pyro-mcp", "pyro", "mcp", "serve"]
}
}
}
When To Use workspace-full
Stay on bare pyro mcp serve unless the chat host truly needs:
- persistent PTY shell sessions
- long-running services and readiness probes
- secrets
- guest networking and published ports
- stopped-workspace disk inspection or raw ext4 export
When that is necessary:
pyro mcp serve --profile workspace-full
Recipe-Backed Workflows
Once the host is connected, move to the five real workflows in use-cases/README.md:
- cold-start repo validation
- repro plus fix loops
- parallel isolated workspaces
- unsafe or untrusted code inspection
- review and evaluation workflows
Validate the whole story with:
make smoke-use-cases
