Setting up with Highlight

This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:

  1. Download and install Highlight from highlightai.com/download
  2. Navigate to the plugins tab and select "Add Custom Plugin"
  3. Configure the plugin with the settings below
    Plugin Name MockHero
    Command (node, npx, python, etc.)

    Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.

  4. Enable "Start Automatically" if you want the plugin to start when Highlight launches

From the repository

Use the remote endpoint https://mockhero.dev/mcp/agent if your agent supports remote MCP. For local installation, add the following to your MCP client configuration, replacing <YOUR_API_KEY> with your actual key:

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

Then invoke the exposed tools as needed.

estimate_agent_usage

Estimate MockHero agent-plan cost before generating data. No login or API key is required; include an API key only when you want the estimate to use actual daily usage.

create_agent_checkout

Create a loginless Polar Checkout URL for MockHero's metered agent plan. Polar is the Merchant of Record for checkout, tax collection, and remittance. The card payment step needs a human: present the returned url to your operator together with the estimate_agent_usage cost, keep the claim_token private, then poll check_agent_checkout_status and call claim_agent_api_key once paid.

check_agent_checkout_status

Poll a Polar checkout created by create_agent_checkout using the returned claim_token.

claim_agent_api_key

Claim the MockHero API key after Polar marks the loginless agent checkout as paid. The key is returned once.

generate_test_data

Generate realistic JSON, CSV, or SQL test data from structured tables or a plain-English prompt. Explicit table schemas up to 100 records can run free as a proof-of-work preview; plain-English prompt generation, larger requests, and production usage require a MockHero API key.

generate_from_template

Generate realistic test data from a pre-built MockHero template: ecommerce, blog, saas, or social. Small template previews up to 100 records can run free; larger or production usage requires a MockHero API key.

detect_schema

Convert SQL CREATE TABLE statements or one sample JSON object into a MockHero schema that can be passed to generate_test_data.

list_field_types

List MockHero field types, descriptions, parameters, and examples before building a schema.

list_templates

List MockHero's pre-built schema templates for ecommerce, blog, SaaS, and social apps.

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

- 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.
- WithMOCKHERO_API_KEY(recommended):plain-English prompt generation, larger requests, CSV/SQL output on paid tiers, and metered agent-plan usage.

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

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 viaAuthorization: Bearer mh_YOUR_API_KEY(or theapi_keytool argument) for authenticated calls.

Omit theenvblock entirely to run in free preview mode.

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

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 throughPolaras Merchant of Record.
- create_agent_checkout— pass a billing email; returns a Polar checkout URL and a one-timeclaim_token. A human completes payment in the browser.
- check_agent_checkout_status— poll with theclaim_tokenuntilstatusispaid.
- claim_agent_api_key— exchange theclaim_tokenfor the API key.The key is returned exactly once— store it securely.
- Restart this server withMOCKHERO_API_KEY=mh_...set (recommended path from here on).

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 needMOCKHERO_API_KEY.

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

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

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

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

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

Poll a checkout byclaim_tokenuntil it is paid.

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