CrewAI tools for Quercle web search and URL fetching.

Installation

uv add quercle-crewai

Or with pip:

pip install quercle-crewai

Quick Start

from quercle_crewai import QuercleSearchTool, QuercleFetchTool

# Initialize tools (uses QUERCLE_API_KEY env var by default)
search = QuercleSearchTool()
fetch = QuercleFetchTool()

# Or with explicit API key
search = QuercleSearchTool(api_key="qk_...")
fetch = QuercleFetchTool(api_key="qk_...")

Standalone Tool Usage

Use the tools directly without any agent:

Search

from quercle_crewai import QuercleSearchTool

search = QuercleSearchTool()

# Basic search
result = search.run(query="What is TypeScript?")
print(result)

# With domain filtering
result = search.run(
    query="machine learning tutorials",
    allowed_domains=["*.edu", "*.org"],
    blocked_domains=["ads.com"],
)

Fetch

from quercle_crewai import QuercleFetchTool

fetch = QuercleFetchTool()

result = fetch.run(
    url="https://docs.python.org/3/whatsnew/3.12.html",
    prompt="Summarize the key new features in bullet points",
)
print(result)

Usage with CrewAI Agents

Basic Agent Setup

from crewai import Agent, Task, Crew
from quercle_crewai import QuercleSearchTool, QuercleFetchTool

# Initialize tools
search_tool = QuercleSearchTool()
fetch_tool = QuercleFetchTool()

# Create an agent with Quercle tools
researcher = Agent(
    role="Research Analyst",
    goal="Find and analyze information from the web",
    backstory="You are an expert researcher who finds accurate information.",
    tools=[search_tool, fetch_tool],
    verbose=True,
)

# Create a task
research_task = Task(
    description="Research the latest features in Python 3.13 and summarize them.",
    expected_output="A summary of Python 3.13 features with key highlights.",
    agent=researcher,
)

# Run the crew
crew = Crew(
    agents=[researcher],
    tasks=[research_task],
    verbose=True,
)

result = crew.kickoff()
print(result)

from crewai import Agent, Task, Crew
from quercle_crewai import QuercleSearchTool, QuercleFetchTool

    backstory="Skilled writer who creates well-structured content.",
)

# Tasks
research_task = Task(
    description="Research the benefits and challenges of remote work in 2024.",
    expected_output="Detailed research findings with sources.",
    agent=researcher,
)

writing_task = Task(
    description="Write a blog post based on the research findings.",
    expected_output="A well-written blog post about remote work.",
    agent=writer,
    context=[research_task],
)

# Create and run crew
crew = Crew(
    agents=[researcher, writer],
    tasks=[research_task, writing_task],
    verbose=True,
)

result = crew.kickoff()
