arcade-mcp

par ArcadeAI · ArcadeAI/arcade-mcp

Python framework to scaffold, deploy, and share MCP servers — built-in OAuth, secret management, and one-command client configuration.

Arcade MCP (ArcadeAI) is a Python framework focused on the full server lifecycle: scaffold (arcade new), add tools (including OAuth'd integrations), and deploy to any client. Distinct from Golf in emphasizing distribution — easy to share servers with teammates or users.

{
  "mcpServers": {
    "arcade": {
      "command": "uvx",
      "args": [
        "arcade-mcp"
      ],
      "_inferred": true
    }
  }
}

Ouvrez Claude Desktop → Settings → Developer → Edit Config. Redémarrez après avoir enregistré.

~/.cursor/mcp.json · .cursor/mcp.json
{
  "mcpServers": {
    "arcade": {
      "command": "uvx",
      "args": [
        "arcade-mcp"
      ],
      "_inferred": true
    }
  }
}

Cursor utilise le même schéma mcpServers que Claude Desktop. La config projet l'emporte sur la globale.

VS Code → Cline → MCP Servers → Edit

  "mcpServers": {
    "arcade": {
      "command": "uvx",
      "args": [
        "arcade-mcp"
      ],
      "_inferred": true
    }
  }
}

Cliquez sur l'icône MCP Servers dans la barre latérale Cline, puis "Edit Configuration".

~/.codeium/windsurf/mcp_config.json
{
  "mcpServers": {
    "arcade": {
      "command": "uvx",
      "args": [
        "arcade-mcp"
      ],
      "_inferred": true
    }
  }
}

Même format que Claude Desktop. Redémarrez Windsurf pour appliquer.

~/.continue/config.json
{
  "mcpServers": [
    {
      "name": "arcade",
      "command": "uvx",
      "args": [
        "arcade-mcp"
      ]
    }
  ]
}

Continue utilise un tableau d'objets serveur plutôt qu'une map.

        "args": [
          "arcade-mcp"
        ]
      }
    }
  }
}

Ajoutez dans context_servers. Zed recharge à chaud à la sauvegarde.

Une seule ligne. Vérifiez avec claude mcp list. Supprimez avec claude mcp remove.

Cas d'usage

Usages concrets : arcade-mcp

Scaffold a working MCP server in under 5 minutes with Arcade

👤 Anyone new to MCP development ⏱ ~15 min beginner

Quand l'utiliser : You've never built an MCP and don't want to hand-wire the SDK.

Prérequis
  • uv — astral.sh/uv
Déroulement
  1. Install + create
    Run uv tool install arcade-mcp then arcade new my_server. Open the generated project.✓ Copié
    → Project with example tools
  2. Run locally
    Run uv run server.py and use mcp tools (from f/mcptools) to list what's advertised.✓ Copié
    → Default tools visible
  3. Configure Claude Desktop
    Run arcade configure claude to wire it up.✓ Copié
    → Claude Desktop config updated; server appears on next launch

Résultat : A working MCP you can iterate on without reading spec docs.

Combiner avec : mcptools

Build an MCP tool that calls an OAuth-protected API

👤 Developers integrating third-party SaaS ⏱ ~45 min advanced

Quand l'utiliser : You need Claude to call Reddit/Linear/GitHub on behalf of the user, not your service.

Prérequis
  • OAuth app registered with the target provider — Provider's dev console
Déroulement
  1. Configure OAuth in arcade.yaml
    Set up Reddit OAuth per the example in arcade's README.✓ Copié
    → OAuth provider registered
  2. Write the tool
    Add a tool get_saved_posts that uses the injected OAuth token to hit Reddit's API.✓ Copié
    → Tool works after user authorizes
  3. First run triggers auth
    Call get_saved_posts from Claude — arcade sends the user through the OAuth flow once.✓ Copié
    → Token stored; subsequent calls don't re-prompt

Résultat : User-scoped MCP integrations without you holding credentials.

Share an MCP server with your team using Arcade

👤 Platform / DevEx teams ⏱ ~20 min intermediate

Quand l'utiliser : You built a handy internal MCP and want others to install it in one command.

Déroulement
  1. Publish the project (internal registry or git)
    Publish your arcade project to internal pypi or a tagged GitHub release.✓ Copié
    → Install command ready
  2. Teammates install
    Teammates run uvx <your-package> and arcade configure claude — done.✓ Copié
    → Server appears in their clients

Résultat : New MCP adopted across the team in minutes.

Combinaisons

Associez-le à d'autres MCPs pour un effet X10

arcade + mcptools

Inspect tool surfaces during development

Run mcp tools against my arcade dev server to verify the schema after each change.✓ Copié
arcade + hyper

Compare Python/Arcade vs WASM/hyper for the same tool

Implement the same 'fetch_user' tool in both Arcade and hyper-mcp; benchmark latency.✓ Copié

Coût et limites

Coût d'exécution

Quota d'API
None — framework
Tokens par appel
Depends on tools
Monétaire
Free, open source
Astuce
Use secret scopes per tool instead of global env vars — easier to audit later

Sécurité

Permissions, secrets, portée

Stockage des identifiants : Arcade's secret store; OAuth tokens kept separately from static secrets
Sortie de données : Whatever your tools call

Dépannage

Erreurs courantes et correctifs

arcade command not found after install

Ensure uv's tool bin is on PATH: export PATH=$HOME/.local/share/uv/tools/bin:$PATH

Vérifier : which arcade
OAuth redirect loop

Callback URL mismatch — must exactly match the provider's registered URL, including trailing slash

Tool schema not refreshed in client

Most clients cache; restart the client after adding/removing tools
