Quick answer
Mcpsnoop and Respan Gateway are both strong choices, but they fit different needs. Choose Mcpsnoop if you mainly need debugging unexpected behavior in ai agent-to-server communication — its edge is completely free with no licensing fees or usage limits. Choose Respan Gateway if you need managing multi-provider llm traffic for production ai applications — its edge is combines routing, observability, and evals in a single platform reducing tool sprawl. Mcpsnoop starts at Free; Respan Gateway starts at around $49/month based on usage volume.
Features compared
- Real-time inspection of MCP traffic between agents and servers
- Detailed logging of requests, responses, and protocol messages
- Open-source codebase available on GitHub for full transparency
- Lightweight CLI-based interface for easy integration into dev workflows
- Unified LLM routing across multiple AI providers with a single API endpoint
- Built-in observability including request tracing, latency monitoring, and logging
- Automated evaluations to benchmark and compare model outputs at scale
- Fallback and retry logic to handle provider outages and reduce downtime
Pros & cons
- Completely free with no licensing fees or usage limits
- Open-source code allows full transparency and customization
- Focused scope makes it easy to learn and integrate quickly
- Lacks a graphical user interface, which may deter less technical users
- Limited community and documentation compared to more established debugging tools
- Combines routing, observability, and evals in a single platform reducing tool sprawl
- Provider-agnostic design makes it easy to swap or mix LLM providers
- Saves engineering time by replacing custom middleware with ready-built infrastructure
- Relatively new platform so documentation and community resources are still maturing
- Advanced evaluation customization may require technical setup not suited for non-developers
