Установка

Выберите клиент

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

{
  "mcpServers": {
    "convexskills-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/waynesutton/convexskills",
        "~/.claude/skills/convexskills"
      ],
      "_inferred": true
    }
  }
}

Откройте Claude Desktop → Settings → Developer → Edit Config. Перезапустите после сохранения.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "convexskills-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/waynesutton/convexskills",
        "~/.claude/skills/convexskills"
      ],
      "_inferred": true
    }
  }
}

Cursor использует ту же схему mcpServers, что и Claude Desktop. Конфиг проекта приоритетнее глобального.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "convexskills-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/waynesutton/convexskills",
        "~/.claude/skills/convexskills"
      ],
      "_inferred": true
    }
  }
}

Щёлкните значок MCP Servers на боковой панели Cline, затем "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "convexskills-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/waynesutton/convexskills",
        "~/.claude/skills/convexskills"
      ],
      "_inferred": true
    }
  }
}

Тот же формат, что и Claude Desktop. Перезапустите Windsurf для применения.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "convexskills-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/waynesutton/convexskills",
        "~/.claude/skills/convexskills"
      ]
    }
  ]
}

Continue использует массив объектов серверов, а не map.

~/.config/zed/settings.json

{
  "context_servers": {
    "convexskills-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/waynesutton/convexskills",
          "~/.claude/skills/convexskills"
        ]
      }
    }
  }
}

Добавьте в context_servers. Zed перезагружается автоматически.

claude mcp add convexskills-skill -- git clone https://github.com/waynesutton/convexskills ~/.claude/skills/convexskills

Однострочная команда. Проверить: claude mcp list. Удалить: claude mcp remove.

Сценарии использования

Реальные сценарии: convexskills

Scaffold a new Convex app with realtime + auth + file uploads

👤 Full-stack devs starting a new Convex project ⏱ ~90 min intermediate

Когда использовать: You're starting fresh and want correct Convex patterns from file one.

Предварительные требования

Convex CLI — npm create convex

Поток

Design the schema

Use the convex-schema-validator skill. Design tables for users, projects, and files with proper indices.✓ Скопировано

→ Schema uses v.id(), indices declared, relationships correct
Wire queries and mutations

Use the convex-functions skill. Implement CRUD for projects.✓ Скопировано

→ Query for reads, mutation for writes, no action misuse
Add realtime + file uploads

Use convex-realtime and convex-file-storage to make projects live-update with file attachments.✓ Скопировано

→ React subscribes via useQuery, files stored via storage.generateUploadUrl

Итог: A correctly-structured Convex app you can build on.

Подводные камни

Using actions where mutations suffice — Skill enforces: mutations for DB writes, actions for external I/O

Add a daily cron job that cleans up stale rows

👤 Convex devs adding background maintenance ⏱ ~20 min beginner

Когда использовать: You need a scheduled task without spinning up a worker.

Поток

Use the cron skill

Use convex-cron-jobs. Add a daily job that deletes rows older than 30 days from table sessions.✓ Скопировано

→ crons.ts entry + internal mutation for the cleanup
Test

Give me a way to trigger this manually for testing.✓ Скопировано

→ Dev-only HTTP action or CLI recipe

Итог: A cron running on Convex's managed scheduler.

Подводные камни

Cron runs a query instead of internal mutation — Skill enforces internal mutation for deletes

Audit a Convex app for authorization holes

👤 Devs before a production launch ⏱ ~45 min advanced

Когда использовать: Your app is ready but you haven't pressure-tested auth.

Поток

Run the audit

Use convex-security-audit on this repo. Check every public mutation for proper auth.✓ Скопировано

→ Per-function auth posture with severity
Fix

Apply the fixes with identity checks and fallback to return null for unauthorized reads.✓ Скопировано

→ Functions updated with ctx.auth checks

Итог: Auth tightened before production.

Подводные камни

Relying on 'public=unauthenticated' mental model — Convex public functions are INTERNET-reachable; skill insists on auth checks

Сочетать с: github

Комбинации

Сочетайте с другими MCP — эффект x10

convexskills-skill + github

Skill designs + implements; GitHub MCP opens the PR

Use convexskills to build the feature, then open a PR with the changes.✓ Скопировано

convexskills-skill + playwright-skill

Build Convex backend, then Playwright tests the UI end-to-end

Implement the Convex backend, then write a playwright-skill test that hits the UI and verifies realtime updates.✓ Скопировано

Инструменты

Что предоставляет этот MCP

Инструмент	Входные данные	Когда вызывать
convex-functions	function need	Any function work
convex-schema-validator	data model	Designing or changing tables
convex-realtime	UI use case	Adding reactive UI
convex-cron-jobs	scheduled task	Periodic background work
convex-migrations	schema change	Evolving an existing schema
convex-security-audit	repo	Pre-production review

Стоимость и лимиты

Во что обходится

Квота API: None for the skill; Convex has its own free + paid tiers
Токенов на вызов: 2-6k per skill loaded
Деньги: Free — skill is local. Convex has a generous free tier.
Совет: Name the specific skill (e.g. convex-cron-jobs) to avoid loading the full set.

Безопасность

Права, секреты, радиус поражения

Хранение учётных данных: No credentials in the skill. Convex deploy keys stay in your .env.

Исходящий трафик: None from the skill itself

Convex public functions are Internet-reachable. Always run convex-security-audit before going to production.

Устранение неполадок

Частые ошибки и исправления

Claude writes an action when a mutation suffices

Rule of thumb the skill enforces: DB-only → mutation; external I/O → action.

Schema change breaks existing data

Use convex-migrations skill — it plans safe transitions with backfill.

useQuery doesn't update in realtime

Check reactivity: the query must read the data that changed, not a stale index.

Альтернативы

convexskills в сравнении

Альтернатива	Когда использовать	Компромисс
Manual Convex docs + examples	You're already an experienced Convex dev	Slower onboarding without the skill
Framework-specific fullstack skills	You're not on Convex	Different stack
