Features:

  • Markdown format for human-readable docs
  • JSON format for machine-readable output
  • Extracts descriptions, examples, and scopes from service metadata
  • Save to file with --output flag

Usage:

bash
micro mcp docs                          # Markdown to stdout
micro mcp docs --format json            # JSON format

Usage Examples

Basic Usage:

python
from langchain_go_micro import GoMicroToolkit
from langchain.agents import initialize_agent
from langchain_openai import ChatOpenAI

# Connect to MCP gateway
toolkit = GoMicroToolkit.from_gateway("http://localhost:3000")

# Get tools
tools = toolkit.get_tools()

# Create agent
llm = ChatOpenAI(model="gpt-4")
agent = initialize_agent(tools, llm, verbose=True)

# Use agent!
result = agent.run("Create a user named Alice")

Advanced Features:

python
# With authentication
toolkit = GoMicroToolkit.from_gateway(
    "http://localhost:3000",
    auth_token="your-bearer-token"
)

# Filter by service
user_tools = toolkit.get_tools(service_filter="users")

# Select specific tools
tools = toolkit.get_tools(include=["users.Users.Get", "users.Users.Create"])

# Exclude tools
tools = toolkit.get_tools(exclude=["users.Users.Delete"])

# Call tools directly
result = toolkit.call_tool("users.Users.Get", '{"id": "user-123"}')

Multi-Agent Workflows:

python
# Specialized agents for different services
user_agent = initialize_agent(
    toolkit.get_tools(service_filter="users"),
    ChatOpenAI(model="gpt-4")
)

order_agent = initialize_agent(
    toolkit.get_tools(service_filter="orders"),
    ChatOpenAI(model="gpt-4")
)

# Coordinate between agents
user = user_agent.run("Create user Alice")
order = order_agent.run(f"Create order for {user}")
