On 2026-10-27 the server answered initialize and tools/list without a sign-in. First answer in 183 ms.

• Answered on only 2 of 7 daily checks.
• Its tools do every use case we checked: Load test a web app without writing scripts; Find whether CPU, memory or the database runs out first; Check whether a bigger server would actually help.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

• Every tool passes all six checks.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• start_load_test

  Load tests the user's app on a real cloud server and returns a run id. The target is a public or connected GitHub repository URL, or a Docker image. Lite is free once per person (500 users, 4 minutes). Standard (2,500 users, 10 minutes)…

• get_test_status

  Where a run stands: building, starting servers, running (with live users, requests per second, p95 latency and error rate) or finished.

• get_test_report

  The full report of a finished run: the verdict, users held, requests per second, p95 latency and errors at each load level, what ran out first, CPU, busiest thread and memory on the server and per service, connections to the database and…

• get_test_timeline

  How a run moved over time: users, requests per second, p95 latency and error rate, averaged into a fixed number of points. Works while a run is going and after it ends.

• list_load_tests

  The account's runs, newest first: id, status, size, target, requests, when it ran and why it failed if it did.

• stop_load_test

  Stops a run that is waiting or running and deletes its servers. A run stopped before its servers were up uses no credit. A run stopped while the load is going is not refunded, and its report covers what was measured until then. Ask the…

• delete_load_test

  Deletes a run and its report and measurements for good. A running run has to be stopped first. Ask the user first.

• set_current_server

  Tells a run which server the user already hosts the app on, so the report says whether that server is enough, how close to the limit it would be and what to change. Or set recommend to true to go back to a recommended size. The report is…

• send_feedback

  Tells Stresix whether a finished run's report was useful, with an optional note. Only send what the user actually said. Sending again replaces the earlier answer.

• inspect_target

  Reads a repository before testing it: the port it listens on, the environment variables the code reads, the framework, whether it needs a database, and its branches. For a Docker image it only checks the reference. Use it before…

• list_github_repos

  The GitHub repositories the user gave Stresix access to, including private ones. Public repositories work without connecting GitHub.

• get_account

  The account's credits, whether the free Lite run is still available, whether GitHub is connected, what each run size costs and the credit packs on sale.

• buy_credits

  Makes a checkout link for a credit pack: Starter is 5 credits for $10, Pro is 25 credits for $40. Nothing is charged by this tool. The user opens the link and pays in their browser, and the credits arrive a minute later. Only call it when…

• redeem_code

  Adds the credits of a promo code to the account. Only use a code the user gave you.
