​
Add Brave Search Tool to AI Agent

​
Quick Start

1

Install Dependencies

Make sure you have Node.js installed, as the MCP server requires it: 

pip install praisonaiagents mcp
2

Set API Key

Set your Brave Search API key as an environment variable in your terminal: 

export BRAVE_API_KEY=your_brave_api_key_here
export OPENAI_API_KEY=your_openai_api_key_here

You can obtain a Brave Search API key from Brave Search API.

3

Create a file

Create a new file brave_search.py with the following code: 

from praisonaiagents import Agent, MCP
import os

# Use the API key from environment or set it directly
brave_api_key = os.getenv("BRAVE_API_KEY") or "your_brave_api_key_here"

# Use a single string command with environment variables
search_agent = Agent(
    instructions="""You are a helpful assistant that can search the web for information.
    Use the available tools when relevant to answer user questions.""",
    llm="gpt-4o-mini",
    tools=MCP("npx -y @modelcontextprotocol/server-brave-search", env={"BRAVE_API_KEY": brave_api_key})
)

search_agent.start("Search more information about AI News")
