MCPProxy Go — High-Performance MCP Proxy
MCPProxy written in Go — a high-performance MCP proxy and aggregator that multiplexes multiple MCP server connections into a single endpoint, providing better performance and resource efficiency than Node.js proxies due to Go's lightweight goroutines and lower memory footprint.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
No proxy auth. Go binary from trusted source. Community. Network security required.
⚡ Reliability
Best When
A production deployment needs to aggregate many MCP servers efficiently — Go's performance and reliability characteristics make this better than Node.js alternatives for high-load scenarios.
Avoid When
You only use 1-2 MCP servers or don't need the performance benefits of a Go implementation.
Use Cases
- • High-performance aggregation of many MCP servers into one connection from production agents
- • Low-latency MCP routing for latency-sensitive agent workflows
- • Resource-efficient MCP server aggregation in constrained environments
- • Production deployments requiring reliable MCP multiplexing from DevOps teams
- • Team-shared MCP server infrastructure with Go-quality reliability
- • Container deployments of MCP aggregation with minimal resource usage
Not For
- • Single MCP server setups (no benefit vs direct connection)
- • Teams not concerned with proxy performance
- • Go binary compilation requirements in restricted environments
Interface
Authentication
No proxy-level authentication. Individual backend MCP servers handle their own auth. Relies on network-level security.
Pricing
Free community Go project. Self-hosted. No external service costs.
Agent Metadata
Known Gotchas
- ⚠ Requires Go binary compilation or pre-built binary download
- ⚠ No proxy-level auth — secure network access separately
- ⚠ Tool namespace collisions between backends possible
- ⚠ Community Go project — less adoption than Node.js alternatives
- ⚠ Configuration is code/config-file based — requires Go knowledge for customization
- ⚠ Backend failures may silently drop tools from aggregated namespace
