Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Page executes code built at runtime src/components/ReadingWidget.astro:157, src/components/landing/DocsGraph.astro:374, src/components/tools/CliBuilder.astro:174 и ещё 5

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 16

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

lookup

lookup_component

Find the dedicated reference page for a JMeter test plan component (e.g. "HTTP Request", "JSON Extractor", "Thread Group") and return its full markdown content with properties, defaults, and related guides.

lookup_error_playbook

Get immediate root causes, OS/JVM config fixes, and remediation steps for common JMeter exceptions (e.g. "BindException", "SocketTimeoutException", "OutOfMemoryError", "NoHttpResponseException", "SSLHandshakeException", "401/403 after recording"). When keywords miss, unmatched text is sent to classifier.dev for zero-shot semantic matching (public keyless calls are not stored).

lookup_function

Find the dedicated reference page for a built-in JMeter function (e.g. "__time", "__Random", "__P") and return its full markdown content with syntax, parameters, and examples.

lookup_jmeter_property

Search or lookup curated JMeter properties (e.g. "httpclient4.idletimeout", "jmeter.save.saveservice.*", "remote_hosts", "summariser"). Returns category, defaults, and recommendations.

convert

convert_curl_or_har_to_jmx

Convert one or more cURL commands or HAR (HTTP Archive 1.2) JSON traces into a valid, production-ready Apache JMeter .jmx test plan XML with HTTP Request Defaults, Header Managers, Cookie Managers, timeouts, and assertions. Supports GET, POST, PUT, DELETE, PATCH, and RFC 9838 QUERY methods.

convert_openapi_to_jmx

Convert an OpenAPI 3.0/3.1 or Swagger 2.0 document (JSON or YAML) into a JMeter 5.6.3 .jmx test plan: servers become HTTP Request Defaults/${BASE_URL}, path parameters become User Defined Variables, request bodies are sampled from schemas, bearer/basic/apiKey security becomes ${AUTH_TOKEN}/${BASIC_AUTH}/${API_KEY}, with optional method, tag, and deprecated-operation filters.

jmeter

get_jmeter_page

Fetch the full markdown text of one docs.jmeter.ai page. Accepts the page URL (e.g. https://docs.jmeter.ai/topics/api-load-testing/) or a bare path (e.g. topics/api-load-testing).

search_jmeter_docs

Search the Apache JMeter documentation on docs.jmeter.ai. Returns the most relevant pages with titles, URLs, and snippets. Use for any question about JMeter test plans, components, functions, properties, distributed testing, reports, or troubleshooting.

lint

lint_groovy_script

Statically analyze a Groovy script for a JMeter JSR223 element. Flags Thread.sleep, ${var} interpolation, System.out, BeanShell APIs, per-call Random or Pattern.compile, and bindings such as prev, SampleResult, or sampler that the selected element type does not expose; optionally returns ready-to-paste JMX element XML.

lint_jmx_snippet

Validate a JMeter test plan XML string or snippet against best practices and performance anti-patterns, and return a structural inventory with thread groups, sampler/listener/assertion counts, HTTP Defaults/Header/Cookie/CSV presence, plugin classes, and JMeter version.

calculate

calculate_workload_model

Compute required thread concurrency, pacing delays, ramp-up schedules, and JVM heap recommendations based on target RPS/TPS and SLA response times using Little's Law.

correlation

get_correlation_sandbox

Generate a ready-to-run Apache JMeter 5.6.3 .jmx practice test plan (either "solved" with Boundary/JSON/Header extractors or "challenge" with broken hardcoded tokens) targeting the live docs.jmeter.ai/api/sandbox endpoints or local localhost:8787 server.

jsr223

get_jsr223_recipe

Fetch production-ready, performant Groovy scripts for JMeter JSR223 samplers, preprocessors, and postprocessors (e.g., JWT parsing & expiration, HMAC-SHA256 signing, dynamic header injection, nested JSON array extraction, custom CSV failure logging).

plan

plan_distributed_testing

Generate Master-Worker RMI port assignments, user.properties, CLI commands, firewall/security group rules, and Docker Compose manifests for distributed load testing.

triage

triage_errors

Map a run's distinct failure signatures to docs.jmeter.ai error playbooks. Error text is sent to classifier.dev for zero-shot classification (public keyless calls are not stored; obvious secrets are redacted first). Prefer signatures shaped as "sampler | response code | response message".

tune

tune_linux_os

Generate production sysctl.conf, limits.conf, systemd overrides, and Docker/K8s configs tuned for high-concurrency JMeter load testing (fixing ulimit nofile, BindException port exhaustion, somaxconn backlog, and JVM swappiness).

JMeter Docs — questions

Answers built from our own checks of this server.

What can JMeter Docs do?

It exposes 16 tools, read directly from the server on our last check. Among them: calculate_workload_model, convert_curl_or_har_to_jmx, convert_openapi_to_jmx, get_correlation_sandbox, get_jmeter_page, get_jsr223_recipe and 10 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is JMeter Docs mostly used for?

Its tools cluster around lookup, jmeter and lint. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is JMeter Docs working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 486 ms. The bar chart above shows every period we have measured.

How do I connect JMeter Docs?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does JMeter Docs need an API key?

No. JMeter Docs completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 16 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is JMeter Docs?

It answers our handshake in 486 ms on average, which is faster than 25% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is JMeter Docs open source?

The code is open source: it is published under the Apache-2.0 licence, written in MDX, 3 stars on GitHub and 9 open issues. The licence covers the code in the repository, not the hosted service at docs.jmeter.ai, which runs on its operator's own terms.
