PR Summary:
• WIP PR proposing dynamic scaling capabilities for containerized deployments
• Comprehensive implementation plan for Kubernetes HPA and Prometheus metrics integration
• No actual code changes yet - currently in planning/design phase
• Addresses issue #17 from AI Development Plan milestone
Review Summary:
This is a well-structured and technically sound implementation plan. I utilized knowledge of the existing deployment infrastructure to provide targeted feedback - the current scripts/deploy-k8s.sh already includes resource requests/limits, so you're building on solid foundations. The proposed Prometheus integration strategy and HPA approach are appropriate for this use case. Since this is a WIP with no code changes (0 additions/deletions), the review focuses on validating the technical approach rather than specific code implementation. Please feel free to provide feedback on this review approach, which I'll incorporate for future reviews.
Follow-up suggestions:
• @devloai help implement Prometheus metrics integration once code is ready
• @devloai review the Kubernetes HPA manifests when implemented

Final ThoughtsThis is a huge upgrade to the Solana MCP Server — adding standard, production-grade monitoring and autoscaling support. Some kinks remain around security hardening, autoscaler robustness, and deployment flexibilities, but overall the architecture and implementation are solid. No major showstopper bugs in code— mostly improvements required around ops and environmental awareness. Great documentation and proper testing gives confidence to ship this 🚢. If this PR were a meme: This code review feature was sponsored by $SVMAI holders. (https://opensvm.com) Prompt for AI AgentsPlease address the comments from this code review:
## Overall Comments
- **🔥 HOLY PROMETHEUS BATMAN!** The PR fully integrates **Prometheus** metrics with clearly labeled counters, histograms, and error types. The metrics are extensive, covering request counts, latencies, successes, failures, and error categorization — just what an observability dream looks like!
- **Axum HTTP Server for /metrics and /health** - clean, async, structured with nice error handling and logging.
- **Kubernetes autoscaling manifests** with CPU, memory, and custom metrics via Prometheus Adapter — this is enterprise-grade stuff.
- **Docker scaling strategy docs and scripts** — much appreciated for users not rocking k8s.
- **Metrics integration in main server logic** — metrics are incremented on request success/failure, nice synergy between app and monitoring layers.
- **Testing coverage** — unit, integration, and docs existence checks? Top marks.
- **Security mindfulness in logs** — sanitizing URLs before logging, non-root container context.
- **Clear docs and bash scripts** — well structured with user-friendly instructions.

Fixed the OpenSSL build issue by adding system OpenSSL installation steps for each platform in the GitHub workflow:
This avoids building OpenSSL from source (which was failing due to missing perl modules) and uses system-provided libraries instead. Build verified locally. Commit: 3f4fa88 |

Final ThoughtsThis is a high-quality PR infusing observability and autoscaling capabilities directly into the Solana MCP Server. It’s like giving your baby rocket thrusters 🚀 alongside a telemetry dashboard with pretty graphs! The integration is neat with production-ready Kubernetes manifests, meaningful docs, and integration tests. The only knocks:
All things considered, this PR does a ton to improve scalability, stability, and operational visibility in a well-documented and thoughtful manner. Very impressive! This code review feature was sponsored by $SVMAI holders. (https://opensvm.com) Prompt for AI AgentsPlease address the comments from this code review:
## Overall Comments
- 🍺 Nice touch to cover Ubuntu, macOS, and Windows package installs!
- 🔥 **But** Windows install uses `choco install openssl` without version pinning or checks if OpenSSL is installed.
- Potential flaky builds if version changes or package not found.
- Also hardcoded `C:\Program Files\OpenSSL-Win64` paths — what if choco installs elsewhere or user runs 32-bit?
- **Suggested fix**: Add verification post-install or use environment variables dynamically. Also consider using `where openssl` or `openssl version` to verify.
- 💅 Style nit: The `echo "OPENSSL_DIR=..." >> $env:GITHUB_ENV` syntax for Windows could be more robust using `$Env:GITHUB_ENV`. Minor fuss, but shell/platform consistency matters. **@copilot** can automate a check on correct env injection.
- 🎉 Finally, observability! The `prometheus` crate and `axum` HTTP server integration looks neat.
## Individual Comments
### Comment 1
`0.0.0.0:8080`
```
- ✅ Using `once_cell::Lazy` with `Arc` for global metrics is idiomatic and thread-safe.
- 🍰 Histogram buckets are well-chosen (from 1ms to 10s). Nice.
- The logging now also updates Prometheus metrics counts alongside in-memory metrics — a smart sync keeping both worlds consistent. Good design.
- Tests cover creating metrics, labels, and server start-up. Excellent for regression catching.
---
```
<issue_to_address>
### 3) **Kubernetes manifests and Autoscaling**
</issue_to_address>
### Comment 2
`0.0.0.0:8080`
```
- In production, this may leak sensitive timing data or internal observations.
- **Action:** Add optional support for bearer token or IP-based filtering; document minimal exposure risk and mitigation.
- **Error handling**: if the metrics server fails to bind (port busy), the error is logged but server continues — good. Maybe log a WARN if metrics fail? Potential to cause confusing silent failures.
- **Configuration hot reload**: Server supports config reload but no documented graceful restart or metrics server restart. Could be future tech debt.
- The CI installs OpenSSL but does not cache it. Maybe worth caching `libssl-dev` and brew formulae to speed builds? Minor ops perf win.
- The macros and logging assume **network** label is always `"mainnet"` hardcoded for Prometheus call. If multi-network usage is eventual, metrics labeling might miss this nuance.
- Suggested: Add metric labels reflecting network IDs dynamically for multi-network support.
- The diff adds some minor typos in docs (missing newline at file ends) — trivial but worth fixing for repo neatness.

Bug: Inconsistent RPC URL Logging
The log_rpc_request_success and log_rpc_request_failure functions inconsistently log the RPC client URL. Many calls pass None for the rpc_url parameter even when client.url() is available, while other calls correctly pass Some(&client.url()). This inconsistency, particularly between success and failure logging for the same RPC method, results in incomplete and incorrect network labeling in Prometheus metrics, often displaying "unknown" instead of the actual network.
