OUR ASSESSMENT

Strengths
  • 2,653 GitHub stars.
  • 100 commits on main in the last 30 days. Top cadence among MCP gateway tooling.
  • Apache-2.0 license.
  • Go binary; no runtime dependencies.
  • Policy-based authentication and routing.
  • Built-in metrics and traffic inspection.
Weaknesses
  • Adds an additional process between agent and MCPs; latency may matter for chatty workloads.
  • Policy configuration has a learning curve; YAML-driven setup.
  • Community-maintained; no commercial vendor backing.
Security Notes

Gateway acts as the auth boundary for downstream MCPs. Misconfigured policies can either over-permit (every backend reachable) or break agent flows entirely. Validate policy changes against a staging gateway before promoting to production.

Best For

Multi-MCP setups where one agent needs to talk to many MCP servers; teams that want auth and observability in front of MCPs; production agent stacks that need policy-based routing and rate limiting.

SOURCES & VERIFICATION

We don't take any single directory's word for it. Before scoring, we cross-reference 4 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.

// How other directories see it

The same server, 4 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
