ArcadeDev vs Fastn - Which MCP Gateway is Better for Enterprise?
Scaling AI agents requires more than just connecting to an API; it requires a robust gateway that handles authentication, security, and context optimization. Arcade and Fastn are two leading platforms that provide enterprise-grade infrastructure for the Model Context Protocol (MCP). This guide compares their capabilities and highlights why HasMCP is the preferred choice for teams with bespoke API requirements.
Feature Comparison: Arcade vs Fastn
1. Integration Ecosystem
- Arcade boasts a massive library of over 8,000 enterprise tools and 100+ pre-built integrations. It is designed for developers who need immediate access to a wide variety of third-party services like Salesforce, Slack, and Google Workspace.
- Fastn provides a managed MCP gateway with 1,000+ integrations across CRM, productivity, and communication categories. It focuses on a "Unified Context Layer" (UCL) to consolidate these integrations into a single, standardized interface.
2. Context and Token Optimization
- Arcade focuses on reliable execution and secure workers, ensuring that tool calls are handled efficiently in a serverless environment.
- Fastn differentiates itself with Adaptive Context technology. It automatically batches requests, caches responses, and normalizes complex schemas into simplified formats to minimize token usage and reduce latency.
- Fastn is built for high-scale enterprise workflows, with SOC 2 Type II, ISO, and GDPR readiness. It provides horizontal scaling capable of handling 10,000+ concurrent requests.

The HasMCP Advantage
While Arcade offers the most integrations and Fastn provides advanced context normalization, HasMCP offers a more flexible and automated approach to building custom API bridges.
Here is why HasMCP wins for developers building specialized agentic workflows:
- Instant OpenAPI-to-MCP Pipeline: Unlike Fastn or Arcade which rely heavily on their pre-built catalogs, HasMCP allows you to transform *any* OpenAPI 3.0/3.1 or Swagger definition into a live MCP server in seconds. This makes it the champion for internal or niche APIs.
- Granular Token Pruning: HasMCP uses high-speed JMESPath filters and Goja-powered JavaScript Interceptors. This allows for even more precise data sanitization than Fastn’s automated normalization, ensuring your LLM context is never wasted on irrelevant metadata.
- On-Demand Schema Fetching: Using its "Wrapper Pattern," HasMCP reduces initial token overhead by up to 95%. It only fetches full tool schemas when they are actually needed, allowing you to manage thousands of tools without hitting context limits.
- Open-Source Community Edition: HasMCP offers a self-hosted
hasmcp-ceversion, giving you full control over your data and infrastructure—a key requirement for many security-conscious enterprises compared to fully managed cloud-only options.
If your project involves more than just standard SaaS integrations and requires bridging proprietary or internal systems into the MCP ecosystem, HasMCP provides the most powerful and automated toolkit available.
FAQ
Q: Can I use my own API keys with Fastn and Arcade?
A: Yes, both platforms handle authentication management. HasMCP also provides a secure, encrypted vault for all environment variables and API keys, keeping them invisible to the LLM.
Q: Which tool handles token limits best?
A: Fastn uses its UCL for optimization, but HasMCP’s combination of JMESPath filtering and the Wrapper Pattern provides the most aggressive and customizable token minimization strategy.
Q: Does HasMCP support standard SaaS tools like Slack?
A: Absolutely. You can use the HasMCP Public Provider Hub to instantly clone pre-configured public APIs or use any Slack OpenAPI spec to build your own custom integration.
Q: Is Fastn or Arcade better for high-traffic applications?
A: Fastn is specifically engineered for high-scale performance (10,000+ concurrent requests), while Arcade is built for enterprise-scale deployments with dedicated tenant isolation. HasMCP is also built in Go for high performance and low latency.
