What is blazemeter-service-virtualization?

Instructions for BlazeMeter Service Virtualization, a testing feature that replaces real services with simulated ones so tests can run without those dependencies.

Use it to create and manage simulated services and their transactions, apply templates, and inspect BlazeMeter tests that use them.

It helps test systems when a real service is unavailable, costly, slow, or difficult to control, while keeping test interactions repeatable.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00104	$0.00887
Opus 5.5	$0.00042	$0.00355
Sonnet 5.5	$0.00021	$0.00177
Haiku 4.5	$0.00010	$0.00089

Security

Grade A, and why

blazemeter-service-virtualization 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 Service Virtualization

Comprehensive guide for creating and managing virtual services in BlazeMeter.

Overview

Service Virtualization enables simulating dependencies and services for testing, supporting transactions, virtual services, templates, and processing actions. This skill covers all aspects from introduction to advanced management.

Quick Start

Introduction: Understand concepts, use cases, and terminology
Transactions: Add transactions from files or manually
Virtual Services: Create virtual services from transactions
Management: Clone, export/import, and manage services
Analytics: Monitor transaction usage and performance

MCP Tools Integration

Service Virtualization services are managed through the BlazeMeter UI, but you can use MCP tools to manage tests that use virtual services:

Available MCP Tools

Test Management:
- blazemeter_tests with action read - Read test details including virtual service 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 virtual service references
Test Execution:
- blazemeter_execution with action read - Read execution details for tests using virtual services
- 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 that use virtual services programmatically
Execution Monitoring: Monitor test executions that interact with virtual services
Automation: Integrate virtual service testing into automation workflows
Reporting: Generate reports on tests using virtual services

Example Workflow

Managing Tests with Virtual Services:

Use blazemeter_tests with action list to find tests using virtual services
Use blazemeter_tests with action read to get test details and virtual service configuration
Use blazemeter_execution with action read to monitor test execution
Review execution results to verify virtual service interactions

What this file has done since we first saw it

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-service-virtualization is a skill published in the GitHub repository Blazemeter/bzm-mcp (26 stars, last pushed 19d ago), licensed Apache-2.0. It adds 104 tokens to every session and 887 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.

Run a candidate against the baseline over an Opik test suite and read the numbers back — which cases broke, which got fixed, the per-metric deltas, worst rows, and whether the two runs are comparable — with the Opik compare-view link.

Turn a failing Opik trace (or a described failure) into a repeatable regression check — a test-suite item with the trace's input and one or two binary assertions — so a fix can be verified by the compare skill. Works over the SDK; uses the MCP write tool when connected. Returns the suite, the item, and the assertion.…

Decide ship or hold for a candidate from the compare skill's numbers, against an explicit release policy — regressions, pass rate, safety-tagged cases, subgroup consistency, latency and cost budgets, flakiness, evidence size, and whether the judge is validated.
