Introduction
MCP vs SNMP is a question that many network professionals are now asking. Network management has long depended on a handful of protocols. Simple Network Management Protocol (SNMP) has been the workhorse for monitoring device health and gathering statistics. NETCONF emerged to address configuration management and security gaps in SNMP. Now a new player—Model Context Protocol (MCP)—is poised to add artificial intelligence into the mix. But how do these protocols compare, and where does MCP fit in the network engineer’s toolkit?
This article examines SNMP, NETCONF and MCP side by side. By understanding each protocol’s architecture, strengths and limitations, you’ll be better equipped to choose the right tool for tasks such as monitoring, configuration management and AI‑driven automation.
SNMP Overview
SNMP was introduced in the late 1980s and remains one of the most widely deployed network management protocols. It exposes management data in the form of variables on managed systems, organized into a management information base (MIB) en.wikipedia.org. Managers query agents on devices to retrieve or sometimes modify these variables. Key points include:
- Versions: SNMP has evolved through three major versions. SNMPv1 is the original protocol; SNMPv2c and SNMPv3 add improvements in performance, flexibility and security en.wikipedia.org. SNMPv3, in particular, introduces authentication and encryption to address security shortcomings.
- Architecture: An SNMP‑managed network consists of managed devices, agents and network management stations (NMSs) en.wikipedia.org. Agents on devices expose data via MIBs, and NMSs poll these agents to gather information or send configuration changes.
- Transport: SNMP operates at the application layer but relies on UDP for transport, using port 161 for queries and port 162 for traps (notifications) en.wikipedia.org. SNMPv3 optionally supports secure transport via TLS/DTLS.
- Data model: MIBs are hierarchical structures of object identifiers (OIDs) that represent variables; each device exposes its own MIB modules en.wikipedia.org. Because the protocol itself does not define which variables a device must expose, vendors can extend MIBs as needed.
- Use cases: SNMP is excellent for basic monitoring (interface counters, uptime, CPU/memory) and supports traps for asynchronous notifications. It is widely supported across routers, switches, access points, printers and more.
SNMP’s simplicity is both a strength and a weakness. It’s easy to implement and has low overhead, but it lacks strong built‑in authentication in older versions, offers limited write capabilities and doesn’t provide a unified way to configure devices. For these reasons, NETCONF emerged to fill the gap.
EyeOTmonitor’s SNMP Implementation
To understand how modern platforms leverage SNMP, it helps to look at EyeOTmonitor’s implementation. EyeOTmonitor uses SNMP to gather device metrics across diverse vendors, but it goes beyond raw polling:
- Pre‑built device models – EyeOTmonitor’s team creates device models so customers don’t have to research MIBs or map properties to OIDs themselves eyeotmonitor.com.
- Intelligent data interpretation – Extraction scripts convert cryptic SNMP values into human‑readable metrics like signal strength, temperature and fan status eyeotmonitor.com.
- Historical tracking and severity rules – The platform stores historical SNMP data and applies severity thresholds to highlight trends and detect degradation eyeotmonitor.com.
- Event and alert management – EyeOTmonitor adds sophisticated alerting logic to avoid alert storms and customize notifications eyeotmonitor.com.
- Cross‑vendor normalization – Predefined models and severity rules provide consistent monitoring across Ubiquiti, Mikrotik, Cambium, Cisco and other vendors eyeotmonitor.com.
These enhancements illustrate how SNMP can be elevated from basic polling to actionable intelligence when combined with context and tooling. As we consider MCP’s role, it’s important to recognize that platforms like EyeOTmonitor can expose SNMP‑driven insights through MCP, allowing AI to query normalized data rather than raw OID values.
NETCONF Overview
The Network Configuration Protocol (NETCONF) was defined by the IETF in 2006 (later updated in RFC 6241) to provide a secure mechanism for installing, manipulating and deleting configuration data on network devices techtarget.com. NETCONF addresses SNMP’s limitations in configuration and security. Core characteristics include:
- RPC‑based model: NETCONF uses a remote procedure call framework. Clients send operations like
<get>
and<edit‑config>
encoded in XML, and servers respond with<rpc-reply>
messages techtarget.com. This allows atomic transactions and structured error handling. - Secure transport: NETCONF is transport‑independent but typically runs over SSH or TLS techtarget.com, ensuring confidentiality and integrity. This makes it suitable for managing configuration changes across insecure networks.
- Data modeling: NETCONF relies on the YANG data modeling language to define configuration and state data models techtarget.com. YANG provides a consistent way to represent device capabilities across vendors.
- Datastores: NETCONF servers maintain configuration datastores (running, candidate, startup) to track changes and commit them atomically techtarget.com.
- Use cases: NETCONF excels at device configuration, bulk changes, and transactional management. It reduces the need for custom CLI scripts and minimizes configuration drift.
While NETCONF improves security and configuration management, it is still primarily a machine‑to‑machine protocol. It is not designed for natural‑language interactions or AI‑driven workflows. That’s where MCP enters the conversation.
Model Context Protocol Overview
The Model Context Protocol bridges AI and external tools. It defines a client‑server architecture wherein a host application (e.g., Claude Desktop) uses an MCP client to discover functions on MCP servers and invoke them using JSON‑RPCdescope.com. Key points include:
- Function standardization: Developers describe functions and parameters in a standard schema descope.com. Any MCP‑compliant AI can discover and call these functions without custom integration.
- Transport options: MCP servers communicate via STDIO for local execution or HTTP+SSE for remote execution descope.com. Both use JSON‑RPC messages for requests and responses.
- Host applications: MCP is integrated into AI clients like Claude Desktop, allowing users to ask natural‑language questions that trigger function calls. The protocol is vendor‑agnostic; it can work with any AI model that supports it.
- Use cases: MCP shines when you need to connect AI systems with existing tools and data sources. For networking, this might include retrieving device metrics, performing diagnostics or initiating configuration workflows through SNMP, NETCONF or proprietary APIs.
MCP does not replace SNMP or NETCONF. Instead, it provides a higher layer of abstraction, enabling AI to orchestrate tasks across these protocols through standardized function calls.
Comparative Analysis
To understand where each protocol fits, let’s compare their architectures, data models, security and use cases.
Aspect | SNMP | NETCONF | MCP |
---|---|---|---|
Core Purpose | Monitoring & basic management of network devices | Secure, transactional configuration management | Standardized AI integration with external tools |
Architecture | Manager–agent model with polling and traps en.wikipedia.org | Client–server RPC with XML messages techtarget.com | Client–server function calls with JSON‑RPC descope.com |
Transport | UDP (v1/v2) or optionally TLS/DTLS (v3) en.wikipedia.org | SSH or TLS over any reliable transport techtarget.com | STDIO (local) or HTTP+SSE (remote) descope.com |
Data Model | MIBs with OIDs en.wikipedia.org | YANG models & XML datastores techtarget.com | Function schemas defined by server developers descope.com |
Security | Minimal in v1/v2; authentication & encryption added in v3 en.wikipedia.org | Strong; runs over SSH/TLS; transactional integrity techtarget.com | Relies on underlying transport (STDIO or TLS) plus server‑level auth; security best practices still emerging |
Use Cases | Polling interface counters, basic alerts, simple config changes | Bulk configuration changes, versioned deployments, transactional updates | AI‑assisted automation; orchestrating SNMP/NETCONF calls; natural‑language queries |
Extensibility | High—vendors can extend MIBs but managing MIBs can be cumbersome | High—YANG allows robust modeling across vendors | High—developers can expose any function as a tool; easily add new integrations |
Strengths and Weaknesses
- SNMP strengths: Universally supported, lightweight and easy to implement. Good for real‑time monitoring and simple alerts. Weaknesses include limited security in older versions and poor support for complex configurations.
- NETCONF strengths: Strong security, transactional integrity and vendor‑agnostic data models. Ideal for configuration management. However, its XML encoding can be verbose, and it still requires knowledge of RPC operations and YANG schemas.
- MCP strengths: Abstracts underlying protocols and enables AI‑driven workflows. Reduces the need for custom integrations and supports natural‑language interactions. It’s vendor‑agnostic and can orchestrate multiple tools. Weaknesses include its nascency (fewer mature tools) and security considerations that depend on implementation.
Choosing the Right Protocol
Selecting the right protocol depends on your goals and environment:
- For basic monitoring and legacy devices: SNMP remains the easiest choice. It is lightweight, widely supported and sufficient for polling counters and receiving traps. Use SNMPv3 when possible to benefit from authentication and encryption en.wikipedia.org.
- For configuration management: NETCONF is designed for changing configurations safely and consistently. Its YANG models provide a structured approach to multi‑vendor device management techtarget.com. Use NETCONF when you need transactional integrity, version control and a secure transport.
- For AI‑driven automation: MCP is the newcomer that bridges AI and existing management tools. Use MCP when you want to expose SNMP, NETCONF or proprietary functions as standardized tools that an AI assistant can call. MCP doesn’t replace lower‑level protocols; it orchestrates them.
In many cases, a hybrid approach works best. For example, you might continue to poll SNMP counters while performing configuration tasks via NETCONF. Then, by exposing these operations through an MCP server, you can let an AI assistant coordinate both monitoring and configuration tasks via natural language.
Conclusion and Key Takeaways
SNMP, NETCONF and MCP each serve distinct but complementary roles in modern network management:
- SNMP is the tried‑and‑true protocol for monitoring device health and gathering metrics en.wikipedia.org. It’s simple and ubiquitous but limited in its write capabilities and security (outside of v3).
- NETCONF provides a secure, transactional way to configure devices, using RPC calls and YANG models techtarget.com. It’s ideal for managing large‑scale configuration changes.
- MCP brings AI into the picture, standardizing how tools expose functions so that AI clients can discover and invoke them descope.com. MCP allows natural‑language queries to drive network operations and orchestrate tasks across SNMP, NETCONF and other protocols.
When used together, these protocols can create a robust, intelligent network management ecosystem. Network engineers should assess their needs—monitoring, configuration, automation—and choose the protocol or combination that best fits those requirements.
