🔧 Prerequisites

Before you begin, ensure you have the following installed:

Python 3.13 or higher
uv package manager (Installation guide)

📦 Installation

Clone the repository:

git clone https://github.com/qainsights/locust-mcp-server.git

Install the required dependencies:

uv pip install -r requirements.txt

Set up environment variables (optional): Create a .env file in the project root:

LOCUST_HOST=http://localhost:8089 # Default host for your tests LOCUST_USERS=3 # Default number of users LOCUST_SPAWN_RATE=1 # Default user spawn rate LOCUST_RUN_TIME=10s # Default test duration

🚀 Getting Started

Create a Locust test script (e.g., hello.py):

from locust import HttpUser, task, between class QuickstartUser(HttpUser): wait_time = between(1, 5) @task def hello_world(self): self.client.get("/hello") self.client.get("/world") @task(3) def view_items(self): for item_id in range(10): self.client.get(f"/item?id={item_id}", name="/item") time.sleep(1) def on_start(self): self.client.post("/login", json={"username":"foo", "password":"bar"})

Configure the MCP server using the below specs in your favorite MCP client (Claude Desktop, Cursor, Windsurf and more):

{ "mcpServers": { "locust": { "command": "/Users/naveenkumar/.local/bin/uv", "args": [ "--directory", "/Users/naveenkumar/Gits/locust-mcp-server", "run", "locust_server.py" ] } } }
