blazemeter-scripting

blazemeter-scripting is a skill for Claude Code, Codex from Blazemeter/bzm-mcp. It costs 105 tokens per session (820 once invoked), scanned A, original, Apache-2.0.

A guide to writing custom code for BlazeMeter tests, including performance tests and API monitoring checks.

In plain words
What is it for?
Use it to write Groovy or Beanshell scripts, use JMeter plugins, create tests with JMeter DSL, and add JavaScript to API Monitoring tests.
Why use it?
It helps when built-in test steps are not enough and you need custom logic, files, plugins, or code-based test definitions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

blazemeter-scripting scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

BlazeMeter Scripting

Comprehensive guide for scripting in BlazeMeter tests.

Overview

Scripting in BlazeMeter supports Groovy/Beanshell for Performance tests, JMeter DSL for code-based test creation, and JavaScript for API Monitoring. This skill covers all scripting capabilities.

Quick Start

  1. Groovy/Beanshell: Write files and custom logic in Performance tests
  2. JMeter Plugins: Use non-standard JMeter plugins
  3. JMeter DSL: Create JMeter tests as code
  4. API Monitoring Scripting: Write custom JavaScript for API Monitoring

MCP Tools Integration

While scripting is primarily done through test configuration and code, you can use BlazeMeter MCP tools to manage tests that use custom scripts:

Available MCP Tools

  • Test Management:

    • blazemeter_tests with action read - Read test details including script configuration
    • blazemeter_tests with action list - List all tests in a project
    • Required args: test_id (integer) or project_id (integer)
    • Returns: Test details including script files and configuration
  • Test Execution:

    • blazemeter_execution with action read - Read execution details for scripted tests
    • blazemeter_execution with action list - List all executions for a test
    • Required args: execution_id (integer) or test_id (integer)
    • Returns: Execution details and results

When to Use MCP Tools

  • Test Management: Manage tests with custom scripts programmatically
  • Script Validation: Verify test scripts are configured correctly
  • Execution Monitoring: Monitor execution of scripted tests
  • Automation: Integrate scripted tests into automation workflows

Example Workflow

Managing Scripted Tests:

  1. Use blazemeter_tests with action list to find tests with custom scripts
  2. Use blazemeter_tests with action read to get test details and script configuration
  3. Use blazemeter_execution with action read to monitor test execution
  4. Review execution results for script-related issues

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

blazemeter-scripting is a skill published in the GitHub repository Blazemeter/bzm-mcp (26 stars, last pushed 16d ago), licensed Apache-2.0. It adds 105 tokens to every session and 820 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
