安装

选择你的客户端

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "spec-workflow-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@pimzino/spec-workflow-mcp@latest",
        "/path/to/project"
      ]
    }
  }
}

打开 Claude Desktop → Settings → Developer → Edit Config。保存后重启应用。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "spec-workflow-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@pimzino/spec-workflow-mcp@latest",
        "/path/to/project"
      ]
    }
  }
}

Cursor 使用与 Claude Desktop 相同的 mcpServers 格式。项目级配置优先于全局。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "spec-workflow-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@pimzino/spec-workflow-mcp@latest",
        "/path/to/project"
      ]
    }
  }
}

点击 Cline 侧栏中的 MCP Servers 图标，然后选 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "spec-workflow-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@pimzino/spec-workflow-mcp@latest",
        "/path/to/project"
      ]
    }
  }
}

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "spec-workflow-mcp",
      "command": "npx",
      "args": [
        "-y",
        "@pimzino/spec-workflow-mcp@latest",
        "/path/to/project"
      ]
    }
  ]
}

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "spec-workflow-mcp": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "@pimzino/spec-workflow-mcp@latest",
          "/path/to/project"
        ]
      }
    }
  }
}

加入 context_servers。Zed 保存后热重载。

claude mcp add spec-workflow-mcp -- npx -y @pimzino/spec-workflow-mcp@latest /path/to/project

一行命令搞定。用 claude mcp list 验证，claude mcp remove 卸载。

使用场景

实战用法： Spec Workflow

Build a feature with a spec, not a vibe prompt

👤 Devs shipping medium-complexity features ⏱ ~90 min intermediate

何时使用： You're about to ask Claude to "add OAuth" and dread the 500-line diff that will land in one go.

前置条件

Project path known — MCP is launched with /path/to/project as arg

步骤

Requirements

Use spec-workflow. Create a spec named oauth-login. Start with requirements — what are we adding, who is it for, what are the non-goals?✓ 已复制

→ Requirements doc drafted, link to dashboard for approval
Approve + Design

I approved in the dashboard. Now write the design: components, data model, sequence diagram, error cases.✓ 已复制

→ Design doc with concrete architecture
Tasks + Execute

I approved. Break into tasks. Then execute task 1.1 — just that one, stop after.✓ 已复制

→ Task list created; only task 1.1 implemented with log entry

结果： A feature shipped with reviewable intermediate artifacts — not a mystery diff.

注意事项

Claude tries to skip straight to code — The MCP blocks it — but be explicit in prompts anyway: "do not implement yet"

搭配使用： github · filesystem

Get a non-engineer stakeholder to approve a spec before code happens

👤 Teams with PM/design sign-off loops ⏱ ~60 min intermediate

何时使用： You need PM approval before implementation and the PM doesn't read GitHub PRs.

前置条件

Dashboard URL shareable — Port-forward or expose localhost:5000 via ngrok for remote PMs

步骤

Spec

Draft the requirements doc for checkout-v2 and share the dashboard URL.✓ 已复制

→ Doc + shareable link
Iterate via feedback

PM left 3 revision comments in the dashboard. Fetch them and revise the doc.✓ 已复制

→ Doc updated with revision history visible
Execute post-approval

Approval just went through — proceed to design.✓ 已复制

→ Next stage starts; approval timestamp logged

结果： Traceable approval chain from non-engineer stakeholders.

注意事项

Dashboard not reachable for remote users — Use Tailscale or ngrok with auth

搭配使用： github

组合

与其他 MCP 搭配，撬动十倍杠杆

spec-workflow-mcp + github

Open a PR per approved task

After executing task 2.1, open a GitHub PR titled "feat(oauth): task 2.1" with the diff.✓ 已复制

spec-workflow-mcp + filesystem

Store specs in-repo alongside code

Save the approved spec to /docs/specs/oauth-login.md and commit.✓ 已复制

工具

此 MCP 暴露的能力

工具	输入参数	何时调用	成本
create_spec	name: str	Start a new feature	free
write_requirements	spec_id, content: markdown	First phase of any spec	free
write_design	spec_id, content: markdown	After requirements approved	free
create_tasks	spec_id, tasks: []	After design approved	free
execute_task	spec_id, task_id	Implement one task at a time	free
get_approval_status	spec_id, stage	Gate next stage	free

成本与限制

运行它的成本

API 配额: Local
每次调用 Token 数: Proportional to doc/task size
费用: Free
提示: Keep requirements concise — the approval cost is human time, not tokens

安全

权限、密钥、影响范围

最小权限： filesystem-write (for spec docs)

凭据存储： None

数据出站： None — localhost dashboard

Don't expose localhost:5000 to the public internet without auth

故障排查

常见错误与修复

Dashboard won't load

Start it explicitly: npx -y @pimzino/spec-workflow-mcp@latest --dashboard

验证： Visit localhost:5000

Port 5000 already in use (macOS AirPlay)

Pass --port 5050 or disable AirPlay Receiver in System Settings

验证： Check with `lsof -i :5000`

Tasks stay in pending after approval

MCP client may be caching old tool results — restart the client

替代方案

Spec Workflow 对比其他方案

替代方案	何时用它替代	权衡
Plain Markdown in /docs	Solo dev with no approval loop needed	No structure enforcement, no dashboard
Linear MCP	You already use Linear for tasks and want Claude to touch issues directly	No spec-doc layer
