Tool Converter

Overview

The ToolConverter automatically detects tool formats and converts them to unified interfaces:

from langcrew.tools import ToolConverter, convert_tools

# Convert any tool
converted = ToolConverter.convert_tool(any_tool)

# Batch convert different formats
unified = convert_tools([crewai_tool, langchain_tool, my_function])

Supported Conversions

CrewAI to LangChain

Convert CrewAI tools to LangChain format:

from crewai_tools import ScrapeWebsiteTool
from langcrew.tools import ToolConverter

# Convert CrewAI tool
crewai_tool = ScrapeWebsiteTool()
langchain_tool = ToolConverter.convert_crewai_tool(crewai_tool)

# Use with any LangChain-compatible agent
result = langchain_tool.run("https://example.com")

LangChain to CrewAI

Convert LangChain tools to CrewAI format:

from langchain_core.tools import BaseTool
from langcrew.tools import convert_langchain_tool

class LangChainCalculator(BaseTool):
    name = "calculator"
    description = "Mathematical calculations"

    def _run(self, expression: str) -> str:
        return str(eval(expression))

# Convert to CrewAI
langchain_tool = LangChainCalculator()
crewai_tool = convert_langchain_tool(langchain_tool)

Function to Tool

Convert functions to tool formats:

from langcrew.tools import ToolConverter

def calculate_interest(principal: float, rate: float, time: int) -> float:
    """Calculate compound interest."""
    return principal * (1 + rate) ** time

# Convert to LangChain tool
tool = ToolConverter.convert_callable_tool(calculate_interest)
result = tool.run({"principal": 1000, "rate": 0.05, "time": 10})

Batch Conversion

Convert multiple tools of different formats at once:

from langcrew.tools import convert_tools

# Mix different tool types
tools = [crewai_tool, langchain_tool, my_function]
unified_tools = convert_tools(tools)  # All become LangChain tools

The Tool Converter provides seamless interoperability between different tool formats, enabling you to use tools from any source in your LangCrew applications without compatibility concerns.
