# Arcade > MCP runtime that securely connects AI agents to APIs, data, and services with OAuth authentication and pre-built integrations. Arcade is the MCP runtime that enables AI agents to securely act on behalf of users across any system. It provides granular permissions, agent-optimized tools, and centralized governance for connecting to email, files, calendars, and APIs. Arcade helps developers ship agents that don't just chat but actually get work done, with the ability to start building in minutes using pre-built tools or custom MCP servers. - **Agent Auth** enables AI to act with secured access to any OAuth-enabled or secret-protected service, from Gmail to custom apps and databases, eliminating token management headaches. - **Pre-Built Connectors** offer battle-tested integrations for popular tools including Gmail, Slack, X, Spotify, and more, with all the heavy lifting already done. - **Custom Tool SDK** allows developers to easily create tailored integrations to extend Arcade's functionality for specific use cases. - **Tool Evaluations** automate and benchmark LLM-Tool interactions for reliable performance, ensuring consistent agent behavior. - **Deploy Anywhere** supports running applications in the cloud, your VPC, or on-premises with Docker, MacOS, Linux, and Kubernetes deployment options. - **MCP Compatible** works seamlessly with the Model Context Protocol, making it enterprise-ready with identity provider connections, agent authorization enforcement, and real actions in Google, Slack, and Salesforce. - **Python and JavaScript SDKs** provide native language support for integrating Arcade into your applications with simple, clean APIs. To get started, sign up for a free account at api.arcade.dev/dashboard/register, which includes 100 user challenges, 1,000 standard tool executions, and 50 pro tool executions. Install the SDK via pip or npm, authenticate users with a few lines of code, and start calling pre-built tools or create custom ones using the Tool Development Kit. The platform integrates with OpenAI, LangChain, and other AI frameworks through a compatible API interface. ## Features - Agent OAuth Authentication - Pre-Built Tool Connectors - Custom Tool SDK - Tool Evaluations - MCP Compatible - Cloud Deployment - Self-Hosted Deployment - Python SDK - JavaScript SDK - OpenAI API Compatible - Granular Permissions - Centralized Governance - Gmail Integration - Slack Integration - Google Calendar Integration - Salesforce Integration ## Integrations Gmail, Slack, Google Calendar, Salesforce, X (Twitter), Spotify, GitHub, OpenAI, LangChain, LangSmith ## Platforms MACOS, LINUX, WEB, API, DEVELOPER_SDK ## Pricing Freemium — Free tier available with paid upgrades ## Links - Website: https://www.arcade.dev - Documentation: https://docs.arcade.dev/home - Repository: https://github.com/ArcadeAI/arcade-ai - EveryDev.ai: https://www.everydev.ai/tools/arcade
