About MockHero MCP Server

Remote MCP server for AI coding agents that need realistic synthetic test data. Agents can estimate usage, create loginless Polar checkout, claim an API key, detect schemas from SQL or JSON, list field types/templates, and generate JSON, CSV, or SQL test data.

MockHero MCP Server tools

9

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 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.

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

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

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 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.

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

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

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

Overview

What is MockHero?

MockHero is an agent-first MCP server for generating realistic synthetic test data. It provides tools for schema detection, templates, authenticated generation, and more, and can be used either via a remote Streamable HTTP endpoint or a local stdio installation.

How to use MockHero?

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:

{

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

Then invoke the exposed tools as needed.
