A hosted MCP server that lets any AI assistant run real load tests for you: import a recording, auto-correlate, validate, run on load generators, read the report. Works with Claude, ChatGPT, Cursor and more. OAuth 2.1, no API key.

Hey Product Hunt, I work at OctoPerf, a load-testing platform that's been around for a while. Load testing has always had the same painful first mile: record a scenario, hunt down every dynamic token so the replay doesn't break, validate, fix, repeat. It's slow and it's the part nobody enjoys. So we built an MCP server that hands that work to whatever AI assistant you already use. You talk to it in plain English. "Import this HAR." "The replay is throwing 401s, fix the correlation." "Run it with 500 users." "Why did the response times spike?" It runs the steps and gives you links back into the OctoPerf UI for anything worth looking at yourself. A few things we cared about: It works with any MCP client, not just one vendor. Claude Code, Claude Desktop, claude.ai, ChatGPT, Cursor, Codex, Gemini CLI, Copilot. It's a plain remote server at a URL. No API key. Login is OAuth 2.1, so there's no secret to paste into a config file, and you can revoke access whenever you want. We obsessed over not wasting your context (and your money). A load test can produce gigabytes of results, so instead of dumping all that into the chat we keep responses tiny and let the model drill down only when it needs to. Wrote it up here if you're curious: It's live now. For Claude Code it's two lines: /plugin marketplace add OctoPerf/octoperf-claude-plugins /plugin install octoperf@octoperf For everything else, the docs have per-client setup: I'll be around all day. Tell me what's missing, what you'd want it to do, or what you'd never trust an AI to touch in your test setup.
