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:
- Starts a temporary cloudflared tunnel (free, no account needed)
- Uses the public tunnel URL for the simulation
- 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.
