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": {
    "convex-agent-skillz-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/PolarCoding85/convex-agent-skillz",
        "~/.claude/skills/convex-agent-skillz"
      ],
      "_inferred": true
    }
  }
}

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

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "convex-agent-skillz-skill": {
      "command": "git",
      "args": [
        "clone",

        "~/.claude/skills/convex-agent-skillz"
      ],
      "_inferred": true
    }
  }
}

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": {
    "convex-agent-skillz-skill": {
      "command": "git",
      "args": [
        "clone",

        "~/.claude/skills/convex-agent-skillz"
      ],
      "_inferred": true
    }
  }
}

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

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "convex-agent-skillz-skill": {
      "command": "git",
      "args": [

        "~/.claude/skills/convex-agent-skillz"
      ],
      "_inferred": true
    }
  }
}

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "convex-agent-skillz-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/PolarCoding85/convex-agent-skillz",
        "~/.claude/skills/convex-agent-skillz"
      ]
    }
  ]
}

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "convex-agent-skillz-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/PolarCoding85/convex-agent-skillz",
          "~/.claude/skills/convex-agent-skillz"
        ]
      }
    }
  }
}

加入 context_servers。Zed 保存后热重载。

claude mcp add convex-agent-skillz-skill -- git clone https://github.com/PolarCoding85/convex-agent-skillz ~/.claude/skills/convex-agent-skillz

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： convex-agent-skillz

Add real-time presence to an existing Convex app

👤 Convex devs adding collab features ⏱ ~45 min intermediate

何时使用： You have an app and want Figma-style 'who's here' indicators without running a socket server.

前置条件

Skill copied into your project's .claude folder — git clone https://github.com/PolarCoding85/convex-agent-skillz and copy .claude/ to your project root

步骤

Describe the feature

Using the Convex skillz — add presence to the documents page. Show cursors and usernames.✓ 已复制

→ Claude implements with Convex's presence pattern (mutation + reactive query), not a custom WebSocket
Handle disconnection

What about cleanup when users close the tab?✓ 已复制

→ Specific stale-presence cleanup strategy aligned with Convex conventions

结果： Working presence with proper cleanup.

注意事项

Custom presence pattern that fights Convex's reactivity — Skill steers you toward the idiomatic version; don't override without a reason

搭配使用： filesystem

Integrate Clerk auth with Convex properly

👤 Devs wiring Clerk into a new or existing Convex app ⏱ ~30 min intermediate

何时使用： You picked Clerk and want its Convex integration right the first time.

步骤

Wire the provider

Convex skillz — integrate Clerk auth with Convex. Set up the JWT template and the Convex auth config.✓ 已复制

→ Claude references the right Clerk JWT template name and auth.config.ts setup
Protect queries

Now gate the documents query so only the owner can read.✓ 已复制

→ ctx.auth.getUserIdentity() pattern with proper identity check

结果： Auth that passes code review and doesn't leak across tenants.

Build an AI agent with persistent threads on Convex

👤 Devs building chat or agent products ⏱ ~90 min advanced

何时使用： You want threaded message history that survives across sessions.

步骤

Model threads

Convex skillz — agent threads table + message history + tool calling metadata.✓ 已复制

→ Schema that covers streaming, partial messages, and tool-call state
Hook up streaming

Stream the assistant response back via a reactive query.✓ 已复制

→ Partial-message pattern leveraging Convex's reactivity

结果： A Convex-native agent thread layer ready to scale.

组合

与其他 MCP 搭配，撬动十倍杠杆

convex-agent-skillz-skill + github

Open PRs for feature additions with Convex-conventional diffs

Implement the presence feature, commit and open PR with the Convex skill patterns noted.✓ 已复制

convex-agent-skillz-skill + filesystem

Work across schema, functions, and UI in one session

Update convex/schema.ts, add the mutation, and wire up the React hook.✓ 已复制

工具

此 MCP 暴露的能力

工具	输入参数	何时调用
queries_mutations_actions	feature intent	Any convex/ work
realtime_patterns	feature (presence / streaming / collab)	Real-time features
auth_setup	provider (Clerk / WorkOS / custom)	Wiring auth
durable_ops	workflow intent	Long-running or retry-heavy logic
ai_agent_threads	agent feature description	Agent products on Convex

成本与限制

运行它的成本

API 配额: None from the skill
每次调用 Token 数: Moderate — patterns load as needed by context
费用: Free — skills are local files. Convex itself has its own pricing.
提示: Place skill in project .claude/ rather than global — auto-activation works best scoped to the project.

安全

权限、密钥、影响范围

凭据存储： No credentials in the skill. Your auth provider secrets live in your own env.

数据出站： None from the skill — code stays local

Auth patterns assume you configure JWT templates correctly in Clerk/WorkOS — read their docs in addition.

故障排查

常见错误与修复

Skill not invoked — Claude writes non-Convex-idiomatic code

Say 'use the Convex skillz' or ensure you're working inside convex/ directory.

验证： ls <project>/.claude/agents/convex-expert.md

SKILL.md frontmatter wrong

Re-copy .claude/ from the repo.

验证： head <project>/.claude/skills/*/SKILL.md

Wrong trigger keywords — auth pattern doesn't use your provider

Name the provider explicitly ('with Clerk' / 'with WorkOS').

替代方案

convex-agent-skillz 对比其他方案

替代方案	何时用它替代	权衡
Convex official docs	You want primary source rather than a curated skill	No in-agent auto-activation
Hand-rolled patterns	You're an experienced Convex dev	You'll reinvent patterns; skill just makes Claude use yours consistently
