安全提示

MCP 服务会接收对话中的工具调用请求，并可能执行外部操作。启用前请先了解该服务能做什么，并只授予它所需的权限。

注册中心已验证此服务的命名空间属于 mockd.io。它以软件包形式运行，而不是托管端点，因此没有可与该域名比对的端点。

SourceWeft 的检查只涵盖条目是否完整、端点是否响应；不审查服务器的代码，也不审查其工具的行为。

在 README 中添加徽章

概览

AI 生成的概览

mockd 是本地多协议 API 模拟服务器，其内置 MCP 服务器让助手创建模拟接口、管理有状态数据、注入故障并校验请求。

可以做什么: 通过一个本地服务器创建、修改和删除 HTTP、gRPC、GraphQL、WebSocket、MQTT、SSE 与 SOAP 模拟接口。管理有状态资源与多步骤流程，使模拟接口表现得像真实的 CRUD API。导入导出 OpenAPI、Postman、HAR、WSDL、WireMock 与 cURL 的规范与录制。应用混沌配置、故障注入与熔断器，并查看请求日志、校验契约。将模拟接口组织到隔离的工作区，并通过云端隧道共享。
适用场景: 适用于客户端要对接尚不存在、不稳定或调用需付费的 API 时，希望由助手直接搭建和调整模拟接口。也适合跨多种协议的契约校验与故障注入测试。
运行要求: 作为本地进程在用户机器上运行，用 mockd 可执行文件加 mcp 参数启动；该文件以容器镜像、Homebrew、Go 安装或预编译二进制分发。未声明账号、API 密钥或环境变量，可完全离线使用。

安装前请注意

助手可以创建、修改和删除模拟接口、有状态数据与工作区，并可启动监听本地端口的服务器。混沌配置会故意注入错误和延迟。可选的云端隧道会把本地模拟接口通过公开网址暴露，启用前请确认共享内容。

安装

在 SourceWeft 中

打开控制台中的 mockd，将其添加到工作区。
为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照仓库中的启动说明。

Why mockd?

Every other mock tool makes you choose: pick one protocol, install a runtime, bolt on extensions. mockd doesn't.

Legend: ✅ built-in • 🔌 Ext = separate OSS extension • ⚠️ Cloud = only in paid / hosted tier • Partial = limited implementation • roadmap = on the project's stated roadmap, not yet shipped

Note on WireMock imports. The ⚠️ Cloud marks on OpenAPI and Postman import reflect first-party WireMock features. Community converters exist (e.g. openapi-to-wiremock, OpenAPI Generator targets) but are not bundled with the OSS standalone JAR.

Digital Twins

Import a real API spec, bind it to stateful tables, and get a mock that passes the real SDK:

yaml

# mockd.yaml — Stripe digital twinversion: "1.0"imports:  - path: stripe-openapi.yaml    as: stripetables:  - name: customers    idStrategy: prefix    idPrefix: "cus_"    seedData:      - { id: "cus_1", name: "Acme Corp", email: "[email protected]" }extend:  - { mock: stripe.GetCustomers, table: customers, action: list }  - { mock: stripe.PostCustomers, table: customers, action: create }  - { mock: stripe.GetCustomersCustomer, table: customers, action: get }  - { mock: stripe.PostCustomersCustomer, table: customers, action: update }  - { mock: stripe.DeleteCustomersCustomer, table: customers, action: delete }

# mockd.yaml — Stripe digital twinversion: "1.0"imports:  - path: stripe-openapi.yaml    as: stripetables:  - name: customers    idStrategy: prefix    idPrefix: "cus_"    seedData:      - { id: "cus_1", name: "Acme Corp", email: "[email protected]" }extend:  - { mock: stripe.GetCustomers, table: customers, action: list }  - { mock: stripe.PostCustomers, table: customers, action: create }  - { mock: stripe.GetCustomersCustomer, table: customers, action: get }  - { mock: stripe.PostCustomersCustomer, table: customers, action: update }  - { mock: stripe.DeleteCustomersCustomer, table: customers, action: delete }

bash

mockd start -c mockd.yaml --no-authcurl -X POST localhost:4280/v1/customers -d "name=Test&[email protected]"# → {"id":"cus_a1b2c3","object":"customer","name":"Test","email":"[email protected]"}

mockd start -c mockd.yaml --no-authcurl -X POST localhost:4280/v1/customers -d "name=Test&[email protected]"# → {"id":"cus_a1b2c3","object":"customer","name":"Test","email":"[email protected]"}

Validated with real SDKs:

Stripe: 49/49 stripe-go SDK tests pass
Twilio: 13/13 twilio-go SDK tests pass
OpenAI: openai Python SDK verified (models, assistants, chat completions)

See mockd-samples for complete digital twin configs.

AI-Native (MCP)

mockd includes a built-in Model Context Protocol server with 18 tools. AI agents can create mocks, manage state, import specs, and verify contracts without touching the CLI:

Works in Claude Desktop, Cursor, Windsurf, and any MCP-compatible editor. Tools cover mock CRUD, stateful resources, chaos injection, request logs, verification, workspaces, and import/export.

Features

Multi-Protocol Mocking — 7 protocols, unified CLI

Protocol	Port	Example
HTTP/HTTPS	4280	`mockd add http --path /api/hello --body '{"msg":"hi"}'`
gRPC	50051	`mockd add grpc --proto svc.proto --service Greeter --rpc-method Greet`
GraphQL	4280	`mockd add graphql --path /graphql --operation hello`
WebSocket	4280	`mockd add websocket --path /ws --echo`
MQTT	1883	`mockd add mqtt --topic sensors/temp --payload '{"temp":72}'`
SSE	4280	`mockd add http --path /events --sse --sse-event 'data: hello'`
SOAP	4280	`mockd add soap --path /soap --operation GetWeather --response '<OK/>'`

Import & Export — OpenAPI, Postman, HAR, WireMock, cURL, WSDL

bash

mockd import openapi.yaml           # OpenAPI 3.x / Swagger 2.0mockd import collection.json        # Postman collectionsmockd import recording.har          # HAR filesmockd import wiremock-mapping.json  # WireMock stubsmockd import service.wsdl           # WSDL → SOAP mocksmockd import "curl -X GET https://api.example.com/users"  # cURL commandsmockd export --format yaml > mocks.yaml

Chaos Engineering — latency, errors, circuit breakers

bash

mockd chaos apply flaky       # 30% error ratemockd chaos apply slow-api    # 200-800ms latencymockd chaos apply offline     # 100% 503 errorsmockd chaos disable

Cloud Tunnel — share local mocks instantly

All 7 protocols multiplexed through a single secure connection on port 443. Works behind NAT and firewalls.

Workspaces — isolated mock environments

bash

mockd workspace create -n "Payment API" --usemockd import stripe-openapi.yamlmockd workspace create -n "Comms API" --usemockd import twilio-openapi.yaml# Mocks, state, and logs are fully isolated per workspace

mockd workspace create -n "Payment API" --usemockd import stripe-openapi.yamlmockd workspace create -n "Comms API" --usemockd import twilio-openapi.yaml# Mocks, state, and logs are fully isolated per workspace

Proxy Recording — record real traffic, replay as mocks

bash

mockd proxy start --port 8888# Configure your app to use http://localhost:8888 as proxy# Traffic is recorded, then replay with:mockd import recordings/session.json

mockd proxy start --port 8888# Configure your app to use http://localhost:8888 as proxy# Traffic is recorded, then replay with:mockd import recordings/session.json

Web Dashboard — manage mocks visually

Release builds serve a web UI from the admin port (http://localhost:4290). VS Code-style editor, command palette, mock tree with folders, request log viewer, and near-miss debugging.

Mockd Cloud

mockd works fully offline with no account required. For teams that want shared environments:

Persistent cloud mocks — deploy mock environments your whole team can hit
Team management — shared workspaces with access controls
Cloud tunnels — authenticated tunnels with custom domains

Coming soon. Join the waitlist.
