RunMCP vs Fastn - API Orchestrator or Adaptive Context Gateway?
Integrating AI agents into enterprise workflows requires both a robust API orchestrator and a high-performance gateway. RunMCP is a lightweight, extensible gateway and orchestrator, while Fastn offers a managed MCP gateway focused on adaptive context for the enterprise. This guide compares their different roles.
Feature Comparison: RunMCP vs Fastn
1. Functional Methodology
- RunMCP is an Extensible Gateway & Orchestrator. It acts as a lightweight control plane for managing multiple MCP servers. It is strictly "API-First," where all routing and orchestration are driven by OpenAPI specifications to ensure contract-driven deployments.
- Fastn is a Managed Action Gateway. Its core value is the "Unified Context Layer" (UCL), which consolidates toolsets into a single server. It focuses on token minimization, schema normalization, and engineering tools for high-scale performance.
2. Capabilities and Monitoring
- RunMCP focuses on Dynamic Configuration and Plugins. It allows you to easily add or update services via config files or API without downtime. Its extensible plugin system supports custom auth flows and monitoring agents like Datadog.
- Fastn focuses on Enterprise Scale and Compliance. It is SOC 2, ISO, and GDPR-ready, providing built-in RBAC and compliance policy enforcement. It is engineered for environments requiring 10,000+ requests per second with deep performance telemetry.
3. Target User Experience
- RunMCP is aimed at Infrastructure and DevOps Teams who need an extensible, lightweight, and OpenAPI-driven gateway to orchestrate multiple internal MCP servers.
- Fastn is aimed at Enterprise Infrastructure Teams who need to manage a massive numbers of tools (1,000+ connectors) at high volume while maintaining strict data governance and token efficiency.

The HasMCP Advantage
While RunMCP orchestrates the APIs and Fastn scales the gateway context, HasMCP provides the automation-first bridge that turns your proprietary APIs into efficient agents with zero manual coding.
Here is why HasMCP is the winner for modern engineering teams:
- Professional Tool Generation from OpenAPI: Both RunMCP and HasMCP are OpenAPI-driven. However, while RunMCP acts as an orchestrator, HasMCP *instantly transforms* an entire specification into a structured, production-ready MCP server. If you have an API, you have a tool in seconds.
- Native Context Optimization: HasMCP goes beyond simple routing by pruning API responses by up to 90% using high-speed JMESPath filters and Goja JavaScript Interceptors. This ensures that your agent stays accurate and costs stay low.
- Dynamic Tool Discovery: To avoid hitting context window limits, HasMCP’s "Wrapper Pattern" fetches full tool schemas only on-demand. This allows you to manage hundreds of custom tools efficiently.
- Self-Host Community Edition (OSS): Like the control you need for enterprise production, HasMCP offers a community edition (
hasmcp-ce). This gives you the power of an automated bridge that you can fully control and self-host for maximum security and data residency.
FAQ
Q: Can I use RunMCP and Fastn together?
A: While both solve orchestration and gateway challenges, RunMCP is a lightweight, extensible orchestrator for individual servers, whereas Fastn is a managed enterprise-grade core designed for massive scale and Unified Context (UCL).
Q: Does RunMCP support plugins?
A: Yes, RunMCP features a highly extensible plugin system that allows you to add custom authentication, monitoring, and request/response manipulation logic to your orchestrator.
Q: How does HasMCP handle secret management?
A: HasMCP includes an encrypted vault for API keys and environment variables, ensuring that sensitive credentials are never exposed to the LLM context.
Q: Which tool is better for a developer starting a new project?
A: RunMCP is a great starting point for extensible orchestration, while HasMCP is the most efficient way to turn your entire internal business logic (OpenAPI) into tools that your agent can actually use.
