概览
MockHero 让助手生成逼真的关系型测试数据（156 种字段类型、22 种语言区域、JSON/CSV/SQL），支持免费预览与可选付费方案。
- 可以做什么
- 根据结构化 schema 或自然语言描述生成测试数据，支持关系外键、多语言区域及 JSON/CSV/SQL 输出
- 使用电商、博客、SaaS、社交等预置模板生成数据
- 将 SQL CREATE TABLE 语句或 JSON 样本转换为 MockHero 的 schema 格式
- 列出支持的字段类型与可用模板
- 估算 agent 方案费用，并完成免登录结账流程：创建结账、查询状态、领取 API 密钥
- 适用场景
- 适合需要为开发、演示或测试准备种子数据或测试夹具，并希望由助手直接生成相互关联的表而无需手写 schema 的场景。免费预览模式可满足小规模显式 schema 或模板请求，密钥可解锁提示词生成与更大规模请求。
- 运行要求
- 可作为本地 npm 包通过 npx 运行（需 Node.js），也可连接远程 Streamable HTTP 端点。可选的 MOCKHERO_API_KEY 用于启用提示词模式、更大请求与 CSV/SQL 输出；MOCKHERO_API_BASE 可覆盖 API 基础地址。免费预览、schema 检测、字段类型列表、模板与费用估算无需密钥。
安装
在 SourceWeft 中
- 打开 控制台中的 MockHero，将其添加到工作区。
- 为需要使用其工具的对话启用该服务。
Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。
交给智能体安装
把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。
阅读 https://sourceweft.com/mcp/io.github.dinosaur24%2Fmockhero/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。其他 MCP 客户端
把它添加到你客户端的 mcpServers 配置中。

@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:
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.

Setup
Claude Desktop
Add to ~/.claude/claude_desktop_config.json:
Omit the env block entirely to run in free preview mode.
Cursor
Add to .cursor/mcp.json in your project:
Claude Code
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-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 with
MOCKHERO_API_KEY=mh_...set (recommended path from here on).

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_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.
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.
