# DNP3 Protocol Analyzer MCP

> DNP3 Protocol Analyzer MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.4/call, status unknown (last checked 2026-10-16).

Analyzes DNP3 industrial protocol data, parsing and extracting structured information from raw DNP3 frames or payloads.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dnp3-protocol-analyzer-mcp-b994e6e3 -d '<json body>'
```

Example prompt: Can you analyze this raw DNP3 protocol data string for me and break down its frame structure, function codes, and data objects: '0564050044001B0081960000'?

## When to prefer this

Choose this endpoint when you need to decode or inspect raw DNP3 protocol frames used in SCADA, ICS, or OT environments such as power grids, water treatment, or oil and gas systems. It is the right choice for troubleshooting DNP3 communications, auditing industrial protocol traffic, or learning the structure of DNP3 packets. Prefer this over generic packet analyzers when DNP3-specific field extraction (function codes, data object groups, internal indications) is required.

## Known failure modes

- Invalid or non-DNP3 data string returns a parse error or empty result
- Malformed hex or encoding causes processing failure
- Truncated frames may result in partial parse with missing fields
- Unsupported DNP3 object groups or variations may not be fully decoded

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a structured breakdown of the DNP3 frame including link layer header (start bytes, length, direction, source/destination addresses), transport layer indicator, application layer (function code, internal indications, data objects with group/variation/index/value), and any detected anomalies or protocol errors.
