BlazeMeter MCP Server

This project provides a Model Context Provider (MCP) server for integrating with BlazeMeter's API, enabling programmatic access to performance test data and management features. The server exposes a set of tools that can be used by MCP-compatible clients (such as Claude Desktop and Cursor) to interact with BlazeMeter resources.

Let's set things up!

🚦 Getting Started

⚙️ Prerequisites

Before starting, please ensure you have:

• Node.js (v18+ required, v20+ recommended)
• npm (included with Node)

Warning: if you run with a lower version of Node, `fetch` won't be present. Tools use `fetch` to make HTTP calls. To work around this, you can modify the tools to use `node-fetch` instead. Make sure that `node-fetch` is installed as a dependency and then import it as `fetch` into each tool file.

📥 Installation & Setup

1. Install dependencies

Run from your project's root directory:

npm install

• On Linux/macOS (sh):

which node

• On Windows (PowerShell):

Get-Command node | Select-Object -ExpandProperty Source

To check the node version, run:

node --version

To get the absolute path to `mcpServer.js`, run:

• On Linux/macOS (sh):

realpath mcpServer.js

• On Windows (PowerShell):

Resolve-Path mcpServer.js | Select-Object -ExpandProperty Path

👩‍💻 Connect the MCP Server to Claude Desktop or Cursor

You can connect your MCP server to any MCP client. Below are instructions for connecting it to Claude Desktop and Cursor.

Claude Desktop

Step 1: Note the full path to node and the `mcpServer.js` from the previous step.

Step 2. Open Claude Desktop → Settings → Developers → Edit Config and add a new MCP server:

{
  "mcpServers": {
    "": {
      "command": "",
      "args": [""]
    }
  }
}

Restart Claude Desktop to activate this change. Make sure the new MCP is turned on and has a green circle next to it. If so, you're ready to begin a chat session that can use the tools you've connected.

Cursor

Step 1: Note the full path to node and the `mcpServer.js` from the previous step.

Step 2. In Cursor, open the Command Palette and search for "MCP: Add Server" or go to Settings → MCP Servers.

Step 3. Add a new MCP server with the following configuration:

• Command: ``
• Arguments: ``

Step 4. Save and enable the server. Cursor will show the MCP server as available, and you can use the BlazeMeter tools directly from the Cursor interface.

Note: For both clients, ensure you use the absolute paths and Node.js v18+.

Warning: If you don't supply an absolute path to a `node` version that is v18+, the client may fall back to another `node` version on the system of a previous version. In this case, the `fetch` API won't be present and tool calls will not work. If that happens, you can a) install a newer version of node and point to it in the command, or b) import `node-fetch` into each tool as `fetch`, making sure to also add the `node-fetch` dependency to your package.json.

Additional Options

🐳 Docker Deployment (Production)

For production deployments, you can use Docker:

1. Build Docker image

docker build -t  .

2. Client Integration

Add Docker server configuration to your MCP client (Claude Desktop or Cursor):

{
  "mcpServers": {
    "": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "--env-file=.env", ""]
    }
  }
}

> Add your environment variables (API keys, etc.) inside the `.env` file.

The project comes bundled with the following minimal Docker setup:

FROM node:22.12-alpine AS builder

WORKDIR /app
COPY package.json package-lock.json ./
RUN npm install

COPY . .

ENTRYPOINT ["node", "mcpServer.js"]

🌐 Server-Sent Events (SSE)

To run the server with Server-Sent Events (SSE) support, use the `--sse` flag:

node mcpServer.js --sse

🛠️ Additional CLI commands

List tools

List descriptions and parameters from all generated tools with:

node index.js tools

Example:

Available Tools:

Workspace: acme-workspace
  Collection: useful-api
    list_all_customers
      Description: Retrieve a list of useful things.
      Parameters:
        - magic: The required magic power
        - limit: Number of results returned
        [...additional parameters...]

🔥 BlazeMeter API Tools

This project includes tools for interacting with the BlazeMeter API. You must set the following environment variables in your `.env` file:

Example .env

BASE_URL=https://a.blazemeter.com
BZM_USERNAME=your_blazemeter_api_key
BZM_PASSWORD=your_blazemeter_api_secret
BZM_ACCOUNT_ID=your_blazemeter_account_id   # (optional, used by workspace-list)
BZM_WORKSPACE_ID=your_blazemeter_workspace_id # (optional, used by project-list)

• For tools where the parameter is optional, the value will be read from `.env` if not provided.
• For tools where the parameter is required, you must provide it in the request.
