MQ-Sentinel

MQ-Sentinel

Production-grade, read-only IBM MQ diagnostic MCP server that AI agents can safely use — with zero hallucinations.

I built this as a serious side project to solve a real, high-stakes problem in enterprise environments. It is now a strong public portfolio piece demonstrating systems engineering, security, observability, production deployment, and building safe infrastructure for AI agents.

[Python 3.12+] [mypy strict] [ruff] [tests 271 passing] [Org-Ready]

0.5.0 — 8 diagnostic tools across all 10 IBM MQ flavors. Read-only by design. Prompt-injection firewall. OIDC + RBAC. Hash-chained audit. Verified IBM Knowledge Center citations (CI-enforced). Production Helm with HPA + air-gapped packaging.

The Problem I Solved

Enterprise IBM MQ teams waste hours diagnosing issues like:

• 2035 NOT_AUTHORIZED storms
• Exploding DLQs
• Native HA replica lag and split-brain
• Stale cluster members
• z/OS mysteries

Traditional tools require deep expertise and manual log diving. Handing an LLM raw MQ access is unacceptable for security and compliance teams.

MQ-Sentinel gives Claude, Cursor, Grok, and other agents a safe MCP interface that returns accurate, cited diagnostics without ever hallucinating or executing destructive commands.

The Problem

IBM MQ teams (banks, telcos, insurance, gov) waste hours on:

• 2035 NOT_AUTHORIZED channel storms
• Exploding DLQs
• Native HA replica lag / split-brain
• Stale cluster members
• z/OS QSG mysteries

Traditional tools require deep MQSC knowledge and grepping logs. Giving an LLM direct MQ access is a non-starter for security/compliance teams.

MQ-Sentinel solves this by giving Claude, Cursor, Grok, etc. a safe, read-only MCP interface that returns typed Root Cause + Fix Steps + verified IBM docs — never fabricates, never executes destructive commands.

Watch MQ-Sentinel diagnose a real 2035 NOT_AUTHORIZED, an INDOUBT channel, a 1247-message DLQ, and a Native HA replica disconnect — all against the bundled fixture sandbox. No live IBM MQ required.

Use it from Claude, Grok, Cursor, Gemini, ChatGPT

One MCP server — not a per-vendor plugin. Copy-paste configs: docs/mcp-clients.md.

List it where agents discover servers: official MCP Registry (server.json) + Smithery (smithery.yaml). ChatGPT needs a hosted HTTPS endpoint, not local stdio.

Safe by design. No LLM inside the server. Every citation verified in CI.

Why This Stands Out as a Portfolio Project

This is not a toy or weekend demo. It demonstrates real engineering depth:

• Systems + Security Engineering: Full threat model, multi-layer read-only enforcement, prompt-injection firewall, OIDC+RBAC, tamper-evident audit, hardened containers, SBOM + signed images.
• Production Operations: Production Helm (HPA, ServiceMonitor, NetworkPolicy), air-gapped packaging (RPM/DEB), observability out of the box.
• AI Agent Infrastructure: A complete, safe MCP server (stdio + HTTP) designed for real use by agents like Claude, Cursor, and Grok.
• Enterprise Domain Expertise: Deep coverage of IBM MQ across 10 topologies with version-aware, verified citations.
• Systematic Delivery: Executed a full 7-phase org-readiness plan with compliance artifacts that actual organizations need.

Built with Grok Build (primary coding partner) while maintaining strict engineering standards.

The Journey (Portfolio Story)

I built MQ-Sentinel to solve a painful, recurring problem in enterprise IBM MQ environments — and I treated the entire effort as a serious engineering and portfolio project.

I used Grok Build (xAI) as my primary coding partner from architecture through implementation, docs, Helm, compliance artifacts, and polish. Every major decision was deliberate: read-only first, citations that can't go stale, defense-in-depth, production packaging.

Key milestones:

• Designed threat model + multi-layer security architecture before writing the first tool
• Delivered 8 diagnostic tools across 10 MQ flavors with CI-enforced IBM Knowledge Center citations
• Production deployment (Helm + HPA + ServiceMonitor, distroless, air-gapped RPM/DEB)
• Full 7-phase org-readiness plan executed (see links above)
• 271+ tests (including security-negative tests), strict mypy, comprehensive docs for platform teams

This shows end-to-end ownership: deep domain knowledge, security by design, production operations, and shipping artifacts that real organizations can actually use.

This is my public portfolio project. It demonstrates systems engineering, security, observability, AI infrastructure, and disciplined delivery.

Built with Grok Build while holding high standards throughout.

Security posture — baked in, not bolted on

• Read-only always. Static MQSC allowlist (DISPLAY / DIS / PING CHANNEL only). Destructive verbs are rejected by three layers: tool, connector, MQ-side setmqaut.
• Prompt-injection firewall. Every MQ-sourced string is sanitized (control chars, zero-width, ANSI, unicode tag chars, jailbreak markers) and wrapped in a quarantine envelope before leaving the server.
• URL allowlist + live verification. Responses may only cite www.ibm.com; all other URLs are redacted. Every citation in the registry (20+ reason codes, 8 AMQ codes, 18 topic pages) is fetched daily in CI — a dead link fails the build, not the customer.
• Tamper-evident audit log. Hash-chained JSONL; mq-sentinel verify-audit detects any retroactive edit.
• OIDC + RBAC. Principals scoped to nonprod-read / prod-read / admin-audit. Cannot query prod QMs from a nonprod token.
• Hardened runtime. Distroless image, non-root, read-only FS, dropped capabilities, seccomp, network egress allowlist.
• Supply chain. SBOM, cosign-signed images, pip-audit + Trivy in CI, every PR security-gated.

Skills & Engineering Rigor (Portfolio Highlights)

What this project demonstrates:

• Systems & Security Engineering — Full threat model, prompt-injection defense, multi-layer read-only enforcement, OIDC+RBAC, hash-chained audit, distroless hardening.
• Observability & Production Operations — Metrics, dashboards, alerts, runbooks, air-gapped packaging, Helm productionization.
• AI Agent Infrastructure — Built a real, safe MCP server (stdio + HTTP) that LLMs can use without risk.
• Enterprise Systems — Deep IBM MQ knowledge across 10 topologies + version-aware diagnostics.
• Software Craftsmanship — 271+ tests (including security), strict mypy, ruff, CI-driven doc verification, SBOM + cosign signing.
• End-to-End Delivery — From idea to org-ready artifacts, including comprehensive documentation that platform teams can actually use.

Built iteratively using Grok Build as the primary coding partner while maintaining high engineering standards.

Install — pick your path

Full guide: docs/INSTALL.md. For IBM MQ client libs: docs/byom.md.

Connect real queue managers

Out of the box MQ-Sentinel serves the bundled demo QM (DEMO_QM). To diagnose your own QMs, set MQS_SERVER_INVENTORY_DIR (QM list) and MQS_SERVER_SECRETS_DIR (credentials), and install the mq extra (pymqi, which needs the IBM MQ client). The server then connects live over a display-only channel. docs/onboard-new-qm.md has the least-privilege setmqaut / CHLAUTH setup.

Quick start (developer / contributor)

Org-Readiness (7-Phase Plan Executed)

This project was deliberately taken through a complete org-readiness program (7 phases) so it is credible for real platform/SRE teams. See the full plan and status:

• docs/ORG-READINESS-PLAN.md
• docs/ORG-READINESS.md — all 7 phases addressed (as of 2026-06-22)

Current state: Ready for platform team evaluation.

Technical Roadmap

Phase 1 (MCP diagnostic tools) is complete. See CHANGELOG.md for future technical items:

• 0.4.0 — ServiceNow / Jira ticket auto-draft from RCS findings.
• 0.5.0 — SOC 2 evidence-pack generator.
• Historical telemetry, air-gapped improvements, etc.

Safe remediation is intentionally out of scope. MQ-Sentinel only reports.
