Mimiq - Synthetic User Testing

Mimiq MCP Server

Your AI coding agent tests pages, copy, and flows on simulated users — automatically, while you build. Spots bad copy, confusing UX, and conversion killers before real users do.

Setup (30 seconds)

Claude Code

claude mcp add --transport http mimiq https://mcp.mimiqai.com/mcp

Or add to .mcp.json in your project root:

{
  "mcpServers": {
    "mimiq": {
      "type": "http",
      "url": "https://mcp.mimiqai.com/mcp"
    }
  }
}

Codex

Add to ~/.codex/config.toml (or .codex/config.toml in your project root):

[mcp_servers.mimiq]
url = "https://mcp.mimiqai.com/mcp"

With an API key, set the env var and reference it:

[mcp_servers.mimiq]
url = "https://mcp.mimiqai.com/mcp"
bearer_token_env_var = "MIMIQ_API_KEY"

Then set the env var: export MIMIQ_API_KEY=mq_sk_your_key_here

Cursor

Add to MCP settings (Settings > MCP):

{
  "mimiq": {
    "transport": "streamable_http",
    "url": "https://mcp.mimiqai.com/mcp"
  }
}

VS Code (GitHub Copilot)

Open Command Palette > "MCP: Add Server" or add to .vscode/mcp.json:

{
  "servers": {
    "mimiq": {
      "type": "http",
      "url": "https://mcp.mimiqai.com/mcp"
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "mimiq": {
      "serverUrl": "https://mcp.mimiqai.com/mcp"
    }
  }
}

Claude Desktop

Add to your Claude Desktop config:

{
  "mcpServers": {
    "mimiq": {
      "transport": "streamable_http",
      "url": "https://mcp.mimiqai.com/mcp"
    }
  }
}

No API key needed — you get 100 free personas to start.

Use it

Your agent now has access to Mimiq tools. It uses them proactively — when it builds or changes a page, it tests automatically. No need to ask.

It also works with localhost. The agent starts a temporary cloudflared tunnel, runs the simulation, and tears it down. You build, it tests, in the same flow.

Or ask directly:

"Test my landing page on startup founders"

"A/B test these two headlines on e-commerce shoppers"

"Ask 20 SaaS founders which pricing model they prefer"

Tools

Tool	What it does
mimiq.test_page	Test a web page — finds UX issues, confusing copy, conversion blockers
mimiq.test_flow	Deep interactive simulation of multi-step flows (signup, checkout)
mimiq.test_copy	Test copy or A/B compare two variants head-to-head
mimiq.test_text	Test any text content (positioning, descriptions, error messages)
mimiq.test_component	Evaluate UI components from HTML snippets
mimiq.ask_audience	Survey a synthetic audience on product decisions

What you get back

Raw per-persona results. Each simulated user has a name, demographics, and independently decides what to do. You get:

• action: what they did (converted, engaged, or bounced)
• monologue: what they were thinking — this is where the real insights are
• objections: specific concerns that stopped them
• what_would_help: what would change their mind
• aggregate counts: how many converted, engaged, or bounced

There are no pre-computed verdicts or scores. Your AI agent analyzes the raw feedback and decides what it means.

When you need more

After 100 free personas, sign up at mimiqai.com to get an API key (Settings > API Keys), then add it to your config:

Claude Code:

claude mcp remove mimiq
claude mcp add --transport http \
  --header="Authorization: Bearer mq_sk_your_key_here" \
  mimiq https://mcp.mimiqai.com/mcp

Codex:

[mcp_servers.mimiq]
url = "https://mcp.mimiqai.com/mcp"
bearer_token_env_var = "MIMIQ_API_KEY"

Then: export MIMIQ_API_KEY=mq_sk_your_key_here

Cursor / VS Code / Claude Desktop / Windsurf — add a headers field:

{
  "headers": {
    "Authorization": "Bearer mq_sk_your_key_here"
  }
}

Pricing

• 100 free personas on first use (no signup needed)
• 2,000 personas for $10 at mimiqai.com/app/usage

Self-hosting

If you're running the Mimiq backend yourself:

cd mcp-hosted
MIMIQ_API_URL=http://127.0.0.1:8000/api node src/server.js

Point your agent at http://127.0.0.1:8787/mcp. In local dev mode, no API key is required.

Docker

cd mcp-hosted
docker build -t mimiq-mcp .
docker run -p 8787:8787 -e MIMIQ_API_URL=http://host.docker.internal:8000/api -e HOST=0.0.0.0 mimiq-mcp

Environment variables

Variable	Default	Description
MIMIQ_API_URL	http://127.0.0.1:8000/api	Mimiq backend URL
MIMIQ_API_KEY	—	Backend API key (if backend requires shared auth)
PORT	8787	Server port
HOST	127.0.0.1	Bind host (0.0.0.0 for Docker)

Testing localhost pages

Mimiq works with localhost out of the box. When your agent calls test_page or test_flow on a local dev server, it automatically:

1. Starts a temporary cloudflared tunnel (free, no account needed)
2. Uses the public tunnel URL for the simulation
3. Tears down the tunnel when done

This is the primary workflow — test while you build, not after you deploy.

Requirement: cloudflared must be installed on the machine running the AI agent.

# macOS
brew install cloudflared

# Linux
curl -L https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64 -o /usr/local/bin/cloudflared && chmod +x /usr/local/bin/cloudflared

The agent handles the rest. No bridge daemon, no extra config, no manual tunnel setup.
