Quick Start
Basic Usage
from hanzo_mcp import create_mcp_server
# Create MCP server
server = create_mcp_server()
# Register tools
server.register_filesystem_tools()
server.register_shell_tools()
server.register_agent_tools()
# Start server
await server.start()
Tool Categories
Filesystem Tools
# Read file
content = await server.tools.read(file_path="/path/to/file.py")
# Write file
await server.tools.write(
file_path="/path/to/new.py",
content="print('Hello')"
)
# Edit file
await server.tools.edit(
file_path="/path/to/file.py",
old_string="old code",
new_string="new code"
)
# Multi-edit
await server.tools.multi_edit(
file_path="/path/to/file.py",
edits=[
{"old_string": "foo", "new_string": "bar"},
{"old_string": "baz", "new_string": "qux"}
]
)
Search Tools
# Unified search (grep + AST + semantic)
results = await server.tools.search(
pattern="function_name",
path="/project"
)
# AST-aware search
results = await server.tools.grep_ast(
pattern="class.*Service",
path="/src"
)
# Symbol search
symbols = await server.tools.symbols(
pattern="def test_",
path="/tests"
)
Shell Tools
# Run command
result = await server.tools.bash(
command="ls -la",
cwd="/project"
)
# Run with auto-backgrounding
result = await server.tools.bash(
command="python server.py",
timeout=120000 # Auto-backgrounds after 2 min
)
# Manage processes
processes = await server.tools.process(action="list")
logs = await server.tools.process(
action="logs",
id="bash_abc123"
)
Agent Tools
# Dispatch agent for complex tasks
result = await server.tools.dispatch_agent(
prompt="Analyze the codebase architecture",
path="/project"
)
# Network of agents
result = await server.tools.network(
task="Implement user authentication",
agents=["architect", "developer", "tester"]
)
# CLI tool integration
result = await server.tools.claude(
args=["--analyze", "main.py"]
)
Batch Operations
# Execute multiple tools in parallel
results = await server.tools.batch(
description="Read multiple files",
invocations=[
{"tool_name": "read", "input": {"file_path": "file1.py"}},
{"tool_name": "read", "input": {"file_path": "file2.py"}},
{"tool_name": "grep", "input": {"pattern": "TODO"}}
]
)
Advanced Features
Custom Tools
from hanzo_mcp import Tool
class MyCustomTool(Tool):
name = "my_tool"
description = "Custom tool"
async def call(self, ctx, **params):
# Tool implementation
return "Result"
# Register custom tool
server.register_tool(MyCustomTool())
Permission Management
from hanzo_mcp import PermissionManager
# Create permission manager
pm = PermissionManager()
# Set permission mode
pm.set_mode("review") # review, auto_approve, auto_deny
# Check permission
allowed = await pm.check_permission(
tool="write",
params={"file_path": "/etc/passwd"}
)
Context Management
from hanzo_mcp import ToolContext
# Create context
ctx = ToolContext(
cwd="/project",
env={"API_KEY": "secret"},
timeout=30000
)
# Use with tools
result = await tool.call(ctx, **params)
