The BlazeMeter Service Virtualization MCP Server connects AI tools directly to BlazeMeter's Service Virtualization platform. This gives AI agents, assistants, and chatbots the ability to manage complete workflows from creation of transactions to deploying it to the virtual service. All through natural language interactions.
- Service Management: Create and manage services.
- Transaction Management: Create, validate, manage HTTP and Messaging transactions.
- Action Management: Create, validate, manage transaction actions (Http calls and Webhooks).
- Asset Management: Upload assets (certificates and keystores).
- Sandbox Management: Attach HTTP transaction and test it.
- Location Management: List available locations.
- Configuration Management: Create and manage configurations for virtual services.
- Virtual Service Management: Create, modify, deploy, stop a virtual service, track its status.
- Virtual Service Templates Management: Create, modify, create from the virtual service, apply to a virtual service.
- BlazeMeter API credentials (API Key ID and Secret)
- Compatible MCP host (VS Code, Claude Desktop, Cursor, Windsurf, etc.)
- Docker (only for Docker-based deployment)
Follow the BlazeMeter API Keys guide to obtain your API keys as JSON.
Important
When downloading your API keys from BlazeMeter, save the api-keys.json file in the same folder where you'll place the MCP binary.

The MCP server supports enabling or disabling specific tools at startup using the environment variable MCP_ENABLED_TOOLS. If the environment variable is not set or is an empty string, all available tools are automatically enabled.
To enable only certain tools, set the environment variable to a comma-separated list of tool names.
Example: MCP_ENABLED_TOOLS="blazemeter_user,blazemeter_account,virtual_services_virtual_service"
- Run main.py with --mcp flag
- Configure your MCP client with the following settings:
{
"mcpServers": {
"virtual services mcp": {
"disabled": false,
"timeout": 60,
"type": "stdio",
"command": "path to your python interpreter /.../venv/bin/python",
"args": [
"path to project main.py /.../sv_mcp/main.py",
"--mcp"
],
"env": {
"API_KEY_PATH": "path to api key file /.../api-key.json"
}
}
}
}{
"id": "your_api_key_id",
"secret": "your_api_key_secret"
}Build dokcer image using the following command:
docker build . -t vs-mcp:latest
{
"mcpServers": {
"Docker BlazeMeter MCP": {
"command": "docker",
"args": [
"run",
"--rm",
"-i",
"-e",
"API_KEY_ID=your_api_key_id",
"-e",
"API_KEY_SECRET=your_api_key_secret",
"-e",
"SOURCE_WORKING_DIRECTORY=/tmp",
"-v",
"/host/path/to/your/test/files:/tmp",
"us-docker.pkg.dev/verdant-bulwark-278/sv-mcp/sv-mcp:latest"
]
}
}
}Important
For Windows OS, paths must use backslashes (\) and be properly escaped as double backslashes (\\) in the JSON configuration.
E.g.: C:\\User\\Desktop\\mcp_test_folder
Note
In order to obtain the API_KEY_ID andAPI_KEY_SECRET refere to BlazeMeter API keys
