Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"crowd-test-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# crowd-test-mcp 🔥 **The mob, on tap — an MCP server for [crowd-test](https://github.com/anhhuyn411-alt/crowd-test).** Ask Claude Desktop, Claude Code, Cursor, or any MCP client to unleash a crowd of AI virtual users — impatient shoppers, confused seniors, keyboard-only users, chaos monkeys — on your website. They browse it in real Chromium, file findings, and hand back a damage report with a **survival grade** (S–F). > *"Send the mob at https://staging.myapp.com and tell me what to fix first."* That's the whole workflow now. ## Install ```bash pip install crowd-test-mcp ``` An LLM key is required in the server's environment: `ANTHROPIC_API_KEY` or `OPENAI_API_KEY`. ### Claude Code ```bash claude mcp add crowd-test -e ANTHROPIC_API_KEY=sk-... -- crowd-test-mcp ``` ### Claude Desktop / Cursor / anything MCP ```json { "mcpServers": { "crowd-test": { "command": "crowd-test-mcp", "env": { "ANTHROPIC_API_KEY": "sk-..." } } } } ``` ## Tools | Tool | What it does | |---|---| | `run_crowd_test` | Send the crowd at a URL. Pick personas, add a random `mob`, set a `goal`, choose the verification depth (`none` / `detective` / `cross` / `tribunal`). Returns a compact damage summary; full markdown/HTML reports land in `~/crowd-test-reports/`. | | `list_personas` | The ten built-in ringleaders and what each one catches. | | `preview_mob` | Preview the random mob a given `count`/`seed` would generate. | | `read_report` | Fetch the newest full markdown report from disk. | ## The verification tribunal Findings can be cross-examined by up to three independent harnesses before they count against the grade — a skeptical detective agent, a raw Playwright probe, and a [Microsoft Webwright](https://github.com/microsoft/Webwright) agent. Automation artifacts get disputed instead of panicking you. Details in the [crowd-test README](https://github.com/anhhuyn411-alt/crowd-test#the-tribunal-%EF%B8%8F). Deeper layers need one-time extras: ```bash pip i…
