Learn how to optimize Cloud Native MCP Server for predictable latency and higher throughput in real production workloads.

Cache and Response Strategy#

The server already includes internal cache and response shaping mechanisms. You can improve performance further by reducing response scope per call:

  • Prefer namespace-scoped queries over cluster-wide queries.
  • Use pagination parameters (for tools that support them) on large datasets.
  • Query only the fields you actually need for the current decision.

Example: Limit payload size#

{
  "method": "kubernetes-get-pods",
  "params": {
    "namespace": "default",
    "limit": 50
  }
}

Tune Kubernetes and Service Timeouts#

Use runtime variables that are supported by the current server:

# Kubernetes client tuning
export MCP_K8S_TIMEOUT=30
export MCP_K8S_QPS=100
export MCP_K8S_BURST=200

# Upstream service request timeout (example: Prometheus)
export MCP_PROM_TIMEOUT=30

These settings should match your cluster size and backend responsiveness.

Control Request Pressure#

For busy environments, apply built-in rate limiting:

export MCP_RATELIMIT_ENABLED=true
export MCP_RATELIMIT_REQUESTS_PER_SECOND=25
export MCP_RATELIMIT_BURST=80

This helps prevent overload during traffic spikes and protects upstream services.

Resource Planning#

Memory#

  • Small environments: 512MB - 1GB
  • Medium environments: 1GB - 2GB
  • Large/high-concurrency environments: 2GB+

CPU#

Cloud Native MCP Server uses optimized encoding and transport paths. In CPU-constrained environments:

  • reduce burst rate
  • reduce query fan-out
  • disable non-required services

export MCP_DISABLED_SERVICES="kibana,jaeger"

Monitor Performance with /metrics#

1

curl -sS http://localhost:8080/metrics

Useful metrics include:

  • http_request_duration_seconds
  • http_requests_total
  • tool_call_duration_seconds
  • tool_calls_total
  • cache_hits_total
  • cache_misses_total

Practical Checklist#

  1. Keep requests narrow and paginated.
  2. Tune MCP_K8S_QPS / MCP_K8S_BURST for your cluster profile.
  3. Set realistic upstream timeouts.
  4. Enable rate limiting in production.
  5. Watch metrics continuously and iterate.
