Claude Code: ask. ### `calculate_workload_model` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `convert_curl_or_har_to_jmx` - The name "convert_curl_or_har_to_jmx" says "convert": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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` - The name "convert_openapi_to_jmx" says "convert": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `get_correlation_sandbox` - The name "get_correlation_sandbox" says "get": a word for reading. - The description's first verb is "generate": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `lint_groovy_script` - The input takes a statement or command to run (input.code), which can change anything it can reach. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `plan_distributed_testing` - The description's first verb is "generate": a word for a change. Description, as the server wrote it: ```untrusted-server-text Generate Master-Worker RMI port assignments, user.properties, CLI commands, firewall/security group rules, and Docker Compose manifests for distributed load testing. ``` ### `triage_errors` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_linux_os` - The description's first verb is "generate": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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). ``` ## Only reads (8) Looks things up and changes nothing. Claude Code: allow. ### `get_jmeter_page` - The name "get_jmeter_page" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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). ``` ### `get_jsr223_recipe` - The name "get_jsr223_recipe" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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). ``` ### `lint_jmx_snippet` - The description's first verb is "validate": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `lookup_component` - The name "lookup_component" says "lookup": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The name "lookup_error_playbook" says "lookup": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The name "lookup_function" says "lookup": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The name "lookup_jmeter_property" says "lookup": a word for reading. Description, as the server wrote it: ```untrusted-server-text Search or lookup curated JMeter properties (e.g. "httpclient4.idletimeout", "jmeter.save.saveservice.*", "remote_hosts", "summariser"). Returns category, defaults, and recommendations. ``` ### `search_jmeter_docs` - The name "search_jmeter_docs" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `jmeter-docs`: ```json { "permissions": { "allow": [ "mcp__jmeter-docs__search_jmeter_docs", "mcp__jmeter-docs__get_jmeter_page", "mcp__jmeter-docs__lint_jmx_snippet", "mcp__jmeter-docs__lookup_jmeter_property", "mcp__jmeter-docs__get_jsr223_recipe", "mcp__jmeter-docs__lookup_error_playbook", "mcp__jmeter-docs__lookup_component", "mcp__jmeter-docs__lookup_function" ], "ask": [ "mcp__jmeter-docs__calculate_workload_model", "mcp__jmeter-docs__lint_groovy_script", "mcp__jmeter-docs__triage_errors", "mcp__jmeter-docs__plan_distributed_testing", "mcp__jmeter-docs__tune_linux_os", "mcp__jmeter-docs__convert_curl_or_har_to_jmx", "mcp__jmeter-docs__convert_openapi_to_jmx", "mcp__jmeter-docs__get_correlation_sandbox" ], "deny": [] } } ```
