Common questions

Is MockHero safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: MOCKHERO_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Supabase, MongoDB MCP Server, Elasticsearch MCP Server

@mockherodev/mcp-server

MCP server for MockHero — generate realistic test data from Claude Desktop, Claude Code, Cursor, Windsurf, and other AI agents.

Works with or without an API key:

No key (free preview): generate up to 100 records per request from explicit table schemas or small templates. Schema detection, field-type listing, templates, and cost estimates are always free.
With `MOCKHERO_API_KEY` (recommended): plain-English prompt generation, larger requests, CSV/SQL output on paid tiers, and metered agent-plan usage.

Hosted agent endpoint

Agents that support remote Streamable HTTP MCP can skip the npm install and connect directly to:

https://mockhero.dev/mcp/agent

The hosted endpoint includes the same tools as this package: cost estimation, loginless Polar checkout, checkout status, API key claiming, schema detection, templates, and data generation. Pass a key via Authorization: Bearer mh_YOUR_API_KEY (or the api_key tool argument) for authenticated calls.

Hosted agent endpoint

Agents that support remote Streamable HTTP MCP can connect directly to:

https://mockhero.dev/mcp/agent

The hosted endpoint includes cost estimation, loginless Polar checkout, checkout status, API key claiming, schema detection, templates, and authenticated data generation.

Setup

Claude Desktop

Add to ~/.claude/claude_desktop_config.json:

"mcpServers": { "mockhero": { "command": "npx", "args": ["@mockherodev/mcp-server"], "env": { "MOCKHERO_API_KEY": "mh_live_your_key_here" } } } }

Omit the env block entirely to run in free preview mode.

Cursor

Add to .cursor/mcp.json in your project:

"mcpServers": { "mockhero": { "command": "npx", "args": ["@mockherodev/mcp-server"], "env": { "MOCKHERO_API_KEY": "mh_live_your_key_here" } } } }

Claude Code

# Free preview mode

claude mcp add mockhero -- npx @mockherodev/mcp-server

Authenticated

claude mcp add mockhero -- env MOCKHERO_API_KEY=mh_live_xxx npx @mockherodev/mcp-server

Get an API key without leaving your agent (loginless checkout)

No signup or dashboard needed. The agent-plan purchase flow is fully tool-driven:

`estimate_agent_usage` — estimate cost first. The agent plan includes 500 free records per day, then $0.001 per 100 records (rounded up per request), billed monthly through Polar as Merchant of Record.
`create_agent_checkout` — pass a billing email; returns a Polar checkout URL and a one-time claim_token. A human completes payment in the browser.
`check_agent_checkout_status` — poll with the claim_token until status is paid.
`claim_agent_api_key` — exchange the claim_token for the API key. The key is returned exactly once — store it securely.
Restart this server with MOCKHERO_API_KEY=mh_... set (recommended path from here on).

Prefer a dashboard? Sign up free at mockhero.dev instead.

Tools

generate_test_data

Generate realistic test data from a structured schema or plain English description. Relational foreign keys, 156 field types, 22 locales, JSON/CSV/SQL output. Explicit schemas up to 100 records run free without a key; prompt mode and larger requests need MOCKHERO_API_KEY.

"Generate 50 users with German names and 200 orders linked to them"

generate_from_template

Generate data from a pre-built template (ecommerce, blog, saas, social) — no schema definition needed. Small scales (e.g. 0.05) stay within the free 100-record preview.

Use the ecommerce template at 2x scale with German locale

detect_schema

Convert SQL CREATE TABLE statements or JSON samples into MockHero's schema format. Free, no key required.

list_field_types

List all 156 supported field types with descriptions and parameters. Free, no key required.

list_templates

List pre-built schema templates. Free, no key required.

estimate_agent_usage

Estimate agent-plan cost before generating: free daily allowance remaining, billable records, billable 100-record units, and estimated dollar cost. Free, no key required.

create_agent_checkout

Create a loginless Polar checkout for the metered agent plan. Returns a checkout URL and one-time claim_token.

check_agent_checkout_status

Poll a checkout by claim_token until it is paid.

claim_agent_api_key

Claim the API key after payment. Returned once — store it and set MOCKHERO_API_KEY.

Environment variables

Variable	Required	Description
`MOCKHERO_API_KEY`	No	MockHero API key (`mh_...`). Without it, generation runs in free preview mode (≤100 records per request, explicit schemas/templates only).

Pricing

Free tier: 500 records/day, 100 per request, JSON output.
