Building an Enterprise-Grade MCP Server Using Agentic AI for IT Operations (Production Support)

1. Executive Overview

IT Operations and Production Support teams are under constant pressure to reduce MTTR, handle alert floods, and maintain uptime across increasingly complex systems. Traditional automation and runbooks help, but they fail when incidents:

  • Span multiple systems

  • Require reasoning instead of static rules

  • Need safe decision-making with governance

This is where Agentic AI powered by an MCP (Model Context Protocol) Server becomes transformational.

This blog is a complete, end-to-end guide — from fundamentals to an enterprise-ready architecture — explaining how to build, deploy, and operate an MCP-based Agentic AI system for real production environments.


2. What Problem Are We Solving in IT Operations?

2.1 Reality of Production Support

In a real enterprise environment:

  • One incident can touch ServiceNow, databases, logs, APIs, and file systems

  • Engineers spend most of their time triaging, not fixing

  • Knowledge is tribal and inconsistent

  • Manual actions introduce risk

2.2 Limitations of Traditional Automation

Traditional AutomationLimitation
ScriptsNo reasoning or context
RunbooksStatic, brittle
Event rulesHigh false positives
RPAUI-dependent, fragile

Conclusion: We need systems that can understand context, reason, decide, and act safely.


3. Key Concepts Explained (Beginner Friendly)

3.1 What is MCP (Model Context Protocol)?

MCP is a standardized interface that allows AI models to:

  • Discover tools

  • Understand input/output schemas

  • Access structured context securely

Think of MCP as a control plane between:

  • AI reasoning engines

  • Enterprise tools (ServiceNow, Kibana, DBs)

MCP = Structured context + tool contracts + governance


3.2 What is Agentic AI?

Agentic AI refers to AI systems that can:

  • Hold goals ("Resolve incident")

  • Make decisions

  • Use tools dynamically

  • Loop until completion or escalation

Agent Loop

  1. Observe → INC, logs, metrics

  2. Reason → What type of failure?

  3. Decide → Best next action

  4. Act → Call tool

  5. Verify → Did it work?

This mirrors how experienced production engineers think.


4. Why MCP + Agentic AI is Perfect for ITOps

CapabilityBenefit
Tool discoveryPlug-and-play automation
Context preservationBetter decisions
Agent reasoningReduced human toil
Governance hooksSafe automation

5. Real Production Support Use Case (End-to-End)

Scenario: Batch File Processing Failure

Trigger:

  • Monitoring detects downstream data missing

  • ServiceNow incident (P2) is created

Incident Description:

"File JD_1023 failed for Storage_ID S88"

Systems Involved:

  • ServiceNow

  • Kibana (logs)

  • MySQL (job status)

  • File server

7. MCP Server Responsibilities

The MCP server is not just a wrapper. It:

  • Exposes enterprise tools safely

  • Enforces schemas

  • Maintains execution boundaries

  • Logs all actions for audit

Typical Tools

  • ServiceNow tools (read/write)

  • Kibana / Elasticsearch queries

  • Database status checks

  • Remediation actions

  • Approval workflows


8. Implementing Real Enterprise Tools

8.1 ServiceNow Integration

Capabilities:

  • Fetch incident details

  • Update work notes

  • Change assignment groups

  • Resolve incidents

@server.tool()
def get_incident(inc_number: str) -> dict:
    return {...}

@server.tool()
def update_incident(sys_id: str, worknote: str, state: str = None):
    pass

8.2 Kibana / Elasticsearch Logs

Logs provide ground truth.

@server.tool()
def fetch_kibana_logs(index: str, file_id: str) -> dict:
    return {...}

Agent reasoning:

  • Error patterns

  • Time correlation

  • Retry detection


9. Agent Reasoning in Action

Decision Tree

  1. Is job failed?

  2. Business or system exception?

  3. Known pattern?

  4. Safe to self-heal?

  5. Approval required?

This logic replaces human mental models.


10. Self-Healing with Guardrails

Example

  • Known system error

  • Retry historically successful

@server.tool()
def restart_job(job_id: str) -> str:
    return "Restart initiated"

Agent then:

  • Monitors logs

  • Verifies success

  • Updates ServiceNow


11. Human-in-the-Loop Approval Workflows

Why Approvals Matter

Automation without governance is dangerous.

Approval triggers:

  • P1 incidents

  • Production restarts

  • Data-impacting actions

@server.tool()
def request_approval(action: str, reason: str) -> str:
    return "Approval requested"

12. Kubernetes Deployment (Production Ready)

Why Kubernetes?

  • Scalability

  • Isolation

  • High availability

  • Secure secrets

kind: Deployment
spec:
  replicas: 2

13. GitHub-Ready Project Structure

mcp-itops-agent/
├── server/
├── tools/
├── agents/
├── approvals/
├── k8s/
├── diagrams/
└── README.md

Designed for enterprise audits and team collaboration.


14. Advanced Multi-Agent Architecture

Specialized Agents

Incident AgentContext extraction
Log AgentRoot cause
DB AgentData validation
Decision AgentClassification
Healing AgentRemediation
Governance AgentCompliance

This mirrors large NOC teams, but automated.


15. Security, Audit & Governance

  • RBAC-based tool access

  • Read vs write separation

  • Full action logging

  • Approval enforcement


16. Business Impact

  • 70–90% reduction in manual triage

  • Faster MTTR

  • Consistent decisions

  • Lower operational risk

  • Happier engineers


17. Final Thoughts

MCP + Agentic AI is not a future concept — it is the next evolution of IT Operations.

Organizations that adopt this approach move from:

Reactive firefighting → Autonomous, self-healing systems


18. Next Enhancements

  • Predictive failure detection

  • Learning from past incidents

  • Cross-domain correlation

  • AI-generated runbooks


This architecture is suitable for:

  • Enterprise production support

  • SRE teams

  • Platform operations

  • AI-driven NOCs

This is how modern IT Operations platforms are built.
