ARCADE AI
The open-source MCP framework for building agent tools
MIT
ABOUT
Building tools for AI agents is fragmented — every agent framework (OpenAI Agents SDK, LangChain, Anthropic, etc.) has its own tool format, auth mechanism, and deployment model. arcade-mcp solves this by providing a unified Python framework for building MCP-compatible tool servers. You define tools with a simple @tool decorator, wire up OAuth once, and the same server works across any MCP-compatible agent. Arcade.dev hosts 7,500+ prebuilt tools covering Gmail, Slack, GitHub, Notion, and more, or you can build private tools for your own services with the same framework.
INSTALL
pip install arcade-mcpINTEGRATION GUIDE
1. Build a custom MCP server that gives your AI agent access to internal APIs, databases, and SaaS tools
2. Use Arcade's 7,500+ prebuilt tools to give an agent Gmail, Slack, GitHub, and Notion access in minutes
3. Deploy a secure tool gateway with built-in OAuth so agents can act on behalf of users without exposing API keys
4. Create a private tool catalog for your organization with usage tracking, rate limits, and access controls
5. Prototype new agent capabilities by decorating a Python function with @tool and testing instantly
