ArcadeDev vs RunMCP - Managed Runtime or API-First Gateway?
For enterprise teams, the choice between a managed runtime and an API-first gateway is fundamental to how they scale their AI agents. Arcade and RunMCP both offer powerful solutions for the Model Context Protocol (MCP), but they approach the challenge from different architectural perspectives. This guide compares Arcade, a specialized MCP runtime, with RunMCP, a lightweight API-first gateway, and shows how HasMCP provides the best of both worlds.
Feature Comparison: Arcade vs RunMCP
1. Architectural Philosophy
- Arcade is a Managed Action Runtime. It provides over 8,000 pre-built enterprise integrations and hosts them in a secure, serverless environment. It is designed for teams that want an "app store" experience for their AI agents, with tools that are ready to go in minutes.
- RunMCP is an API-First Gateway and Orchestrator. It is driven by OpenAPI specifications, ensuring that every tool call and service registration is contract-driven and predictable. It’s designed to be a lightweight control plane for managing multiple MCP servers with dynamic routing and horizontal scalability.
2. Customization and Extensibility
- Arcade excels at User-Centric Authorization and production-scale execution, handling the heavy lifting of user identity and serverless infrastructure out-of-the-box.
- RunMCP excels at Dynamic Configuration and Plugins. It features an extensible plugin system for authentication (OAuth2, API keys), monitoring (Datadog), and custom middleware hooks to transform or validate data before and after requests.
3. Deployment and Scalability
- Arcade simplifies the production lifecycle with managed hosting and comprehensive enterprise audit logs.
- RunMCP is built for high-availability environments and supports horizontal scaling, allowing instances to grow as your API traffic increases.

| Self-Hosting | No (Managed Only) | Yes | Yes (Community Edition) |
The HasMCP Advantage
While RunMCP orchestrates and Arcade executes, HasMCP provides the Automated Infrastructure that bridges the gap between your data and your AI.
Here is why HasMCP is the winning choice:
- Instant OpenAPI-to-MCP Transformation: RunMCP onboarding is fast, but HasMCP is instantaneous. It transforms any OpenAPI 3.0/3.1 or Swagger definition into a production-ready MCP server with zero manual routing configuration.
- Superior Context Window Management: RunMCP focuses on data transformation via middleware, but HasMCP optimizes for the LLM context window itself. Its built-in JMESPath filters and JavaScript Interceptors prune large API responses *at the source*.
- On-Demand Schema Fetching: Through its Wrapper Pattern, HasMCP reduces initial token overhead by up to 95%. It only reveals the full tool schema when the agent needs it, preventing the "context bloat" that can occur in large gateway environments.
- Public Provider Hub: HasMCP features a built-in registry where you can discover and instantly clone pre-configured public APIs, giving you the variety of Arcade with the control of an API-first gateway.
Whether you need the massive catalog of Arcade or the contract-driven routing of RunMCP, HasMCP is the most automated and efficient bridge for your proprietary APIs.
FAQ
Q: Can I use RunMCP to orchestrate my HasMCP servers?
A: Yes. Since HasMCP builds standard MCP servers, they can be registered and routed through RunMCP’s gateway to take advantage of its horizontal scaling and dynamic routing rules.
Q: Does Arcade support OpenAPI for custom tools?
A: Arcade allows you to build custom tools using their SDK, but it doesn't feature the same "API-first" automated onboarding from OpenAPI specs that RunMCP or HasMCP provides.
Q: Is RunMCP a runtime or a gateway?
A: It is primarily a gateway and orchestrator (control plane) that manages the routing and policies between your agents and your various MCP servers.
Q: Which tool is better for high-availability?
A: Both are designed for scale. Arcade handles this through its managed serverless environment, while RunMCP is architected for horizontal scalability within your own infrastructure.
