New package: hanzo-async - Automatic uvloop detection and configuration - Async file I/O (read_file, write_file, append_file, read_json, write_json) - Async path operations (path_exists, is_file, is_dir, mkdir, etc.) - Async subprocess execution (run_command, run_shell) - Graceful fallback to asyncio on Windows or when uvloop not installed Updated packages to use hanzo-async: - hanzo-tools-shell: base_process.py, ps_tool.py, shell_tools.py - hanzo-tools-agent: agent_tool.py, dataset.py - hanzo-tools-fs: search.py - hanzo-mcp: cli.py, auto_timeout.py, event_loop.py, version_tool.py Shell improvements: - Renamed zsh_tool.py to shell_tools.py (better organization) - Added DashTool for Debian/Ubuntu's fast POSIX shell - All shell tools now thin shims over CmdTool Version info now shows async backend: - CLI: hanzo-mcp 0.10.27 (async: uvloop 0.22.1) - Tool: async: uvloop 0.22.1
hanzo-tools-shell
Shell execution tools for Hanzo MCP with DAG support and Shellflow DSL.
Installation
pip install hanzo-tools-shell
Tools
dag - DAG Execution Engine
Execute commands with directed acyclic graph semantics.
# Serial execution (default)
dag(["ls", "pwd", "git status"])
# Parallel execution
dag(["npm install", "cargo build"], parallel=True)
# Mixed DAG with parallel blocks
dag([
"mkdir -p dist",
{"parallel": ["cp a.txt dist/", "cp b.txt dist/"]},
"zip -r out.zip dist/"
])
# Tool invocations
dag([{"tool": "search", "input": {"pattern": "TODO"}}])
# Named nodes with dependencies
dag([
{"id": "build", "run": "make build"},
{"id": "test", "run": "make test", "after": ["build"]},
])
zsh - Primary Shell with Shellflow DSL
Execute shell commands with optional Shellflow syntax.
# Simple command
zsh("ls -la")
# Shellflow DSL syntax
zsh("mkdir dist ; { cp a dist/ & cp b dist/ } ; zip out")
# With shell parameter
zsh("echo $BASH_VERSION", shell="bash")
Shellflow Syntax:
A ; B- Sequential execution{ A & B }- Parallel executionA ; { B & C } ; D- Mixed DAG
ps - Process Management
Monitor and control background processes.
ps() # List all processes
ps(id="abc123") # Get specific process
ps(kill="abc123") # Kill process (SIGTERM)
ps(logs="abc123", n=50) # Last 50 lines of output
Additional Tools
- shell - Smart shell (zsh > bash fallback)
- bash - Explicit bash execution
- npx - Node package execution with auto-backgrounding
- uvx - Python package execution with auto-backgrounding
- open - Open files/URLs in system apps
- curl - HTTP client without shell escaping issues
- jq - JSON processor
- wget - File/site downloads
Auto-Backgrounding
Commands that exceed the timeout (default 60s) are automatically backgrounded:
dag(["long-running-command"], timeout=30)
# If command exceeds 30s, it continues in background
# Use ps --logs <id> to view output
Performance
Shellflow DSL is optimized for high throughput:
- Simple commands: ~7M ops/sec
- Sequential: ~2.2M ops/sec
- Mixed DAG: ~100k ops/sec
