Fastn vs Portkey - Adaptive Context or AI Gateway & Observability?
Scaling AI agents for production requires both tool connectivity and professional-grade infrastructure. Fastn focuses on a managed MCP gateway with a unified context layer, while Portkey offers a comprehensive AI Gateway with advanced observability, guardrails, and prompt management. This comparison explores their different strengths.
Feature Comparison: Fastn vs Portkey
1. Core Infrastructure
- Fastn is a Managed MCP Gateway. Its primary job is to unify over 1,000 integrations into a single MCP server. It uses its "Adaptive Context Layer" (UCL) to handle intent routing and schema normalization, focusing on performance and enterprise governance.
- Portkey is an AI Gateway. It allows teams to access 1,600+ LLMs, vector databases, and frameworks with a single integration. Its core differentiator is "Semantic Caching," which can reduce latency and costs by up to 80% by caching LLM responses.
2. Observability and Monitoring
- Fastn provides Telemetry and Visibility into tool usage and agent reasoning paths. It focuses on the operational efficiency of the MCP connections and compliance with security policies.
- Portkey features a Real-time LLM Dashboard. It monitors cost, latency, token usage, and error rates across all requests, capturing over 40 parameters per request. It also includes "Feedback Loops" to capture user and model feedback directly on LLM responses.
3. MCP Governance
- Portkey provides a centralized governance layer to manage and authenticate MCP tools. It allows for fine-grained access control, defining precisely which agents or users can access specific tools and resources.
- Fastn also provides centralized governance but leans more heavily on its "pre-built library" of integrations, designed to be enterprise-ready (SOC 2, ISO, HIPAA) out-of-the-box.

The HasMCP Advantage
While Fastn excels at the action gateway and Portkey masters the AI gateway and observability, HasMCP provides the automated bridge that connects your proprietary APIs with high-speed, cost-effective efficiency.
Here is why HasMCP is the winner for organizations scaling custom AI tools:
- Instant OpenAPI-to-MCP: Neither Fastn nor Portkey focus on *creating* tools from your own APIs. HasMCP allows you to instantly transform any OpenAPI or Swagger spec into a production-ready MCP server. If you have an internal REST API, it can be an MCP tool in seconds.
- Aggressive Token Pruning: While Portkey caches responses, HasMCP actually prunes them *before* they hit the LLM. Using high-speed JMESPath filters and Goja JavaScript Interceptors, HasMCP can reduce token usage by up to 90%, preventing "context bloat" in every turn.
- Dynamic Tool Discovery: To keep initial token overhead low, HasMCP’s "Wrapper Pattern" only fetches full tool schemas when they are actually called. This ensures that you can expose hundreds of tools to an agent without overwhelming the context window.
- Self-Host Community Edition (OSS): For teams that need to keep their tool execution and API proxying in-house, HasMCP offers an open-source community edition. This gives you the power of an automated MCP bridge with full control over your data residency.
FAQ
Q: Can I use Fastn and Portkey together?
A: Yes, Portkey's AI gateway can sit in front of any MCP server, including those managed by Fastn, to provide advanced observability and caching.
Q: Does Portkey handle OAuth for my tools?
A: Portkey provides a governance layer for managing and authenticating tools, while Fastn is more focused on being a "managed host" for standard enterprise auth flows.
Q: How does HasMCP handle secret management?
A: HasMCP included an encrypted vault for API keys and environment variables, ensures that sensitive credentials are never exposed to the LLM during tool calls.
Q: Which tool is better for reducing LLM costs?
A: Portkey’s semantic caching is excellent for repeating queries, while HasMCP’s token pruning and dynamic tool discovery reduce the base cost of every individual request.
