Fastn vs RunMCP - Managed Gateway or Extensible Orchestrator?
The Model Context Protocol (MCP) requires a robust control plane for managing the connection between AI agents and enterprise tools. Fastn provides a managed gateway focused on adaptive context, while RunMCP is a lightweight, extensible gateway and orchestrator designed for API-first deployments. This guide compares their different architectural priorities.
Feature Comparison: Fastn vs RunMCP
1. Architectural Philosophy
- Fastn is a Managed MCP Gateway. Its core is the "Unified Context Layer" (UCL), which consolidates integrations into a single server using adaptive routing and schema normalization. It is designed for high-scale enterprise environments where "Infrastructure-as-a-Service" is the goal.
- 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.
2. Capabilities and Scalability
- Fastn is engineered for Enterprise High-Scale, handling 10,000+ concurrent requests with low latency. It focuses on "tool mastery" and built-in governance (SOC 2, ISO, HIPAA) out-of-the-box.
- 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 (OAuth2, API keys), monitoring (Datadog), and traffic shaping (Middleware).
3. Developer Experience
- Fastn provides a dedicated React component for frontend development and focuses on low-code/no-code bridging between agents and legacy systems.
- RunMCP offers a "Zero-Config Onboarding" experience: register an OpenAPI spec and go live instantly. It is aimed at developers who need a highly customizable, self-hosted orchestrator for their multi-tenant, API-driven architectures.

The HasMCP Advantage
While Fastn excels at scaling the managed gateway and RunMCP masters extensible orchestration, HasMCP provides the automation-first bridge that turns your APIs into agents with a focus on speed, efficiency, and zero manual coding.
Here is why HasMCP is the winner for modern API teams:
- Instant OpenAPI-to-MCP transformation: Like RunMCP, HasMCP is OpenAPI-driven. However, HasMCP *instantly* transforms any 3.0/3.1 definition into a production-ready MCP server with no manual boilerplate. If you have an API, you have a professional-grade MCP tool in seconds.
- Deep Token Pruning: HasMCP goes beyond simple routing by offering high-speed JMESPath filters and Goja JavaScript Interceptors. These allow you to prune API responses by up to 90%, preventing the "context bloat" that distracts LLMs and increases costs.
- Dynamic Tool Discovery: HasMCP's "Wrapper Pattern" fetches full tool schemas only on-demand. This reduces initial token overhead by up to 95%, allowing you to manage massive numbers of tools (the "API mesh" goal of RunMCP) without hitting context limits.
- Self-Host Community Edition (OSS): Like RunMCP, HasMCP offers a self-hostable community edition (
hasmcp-ce). This gives you full control over your data residency and source-controlled GitOps integrations, making it a powerful, automated alternative to building your own orchestrator.
FAQ
Q: Does Fastn support multi-tenant environments?
A: Yes, Fastn is designed with native multitenancy support to manage secure, isolated environments for multiple organizations or customers.
Q: Can I use RunMCP with existing MCP servers?
A: Yes, RunMCP serves as a control plane that can manage and orchestrate access to multiple local or remote MCP servers.
Q: How does HasMCP handle custom auth?
A: HasMCP supports native OAuth2 elicitation, meaning the agent can securely prompt the user for their credentials in real-time, keeping sensitive API keys out of the LLM context.
Q: Which tool is better for a "Serverless" architecture?
A: Fastn’s managed cloud is inherently serverless, but HasMCP also provides a managed cloud option for teams that want a zero-infrastructure automated bridge.
