# Modbus RTU/TCP Parser MCP

> Modbus RTU/TCP Parser MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.12/call, status unknown (last checked 2026-10-18).

Parses and decodes Modbus RTU and TCP protocol data frames, extracting register values and field meanings from raw industrial communication data.

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 modbus-rtu-tcp-parser-mcp-3ed9a650 -d '<json body>'
```

Example prompt: Can you parse this raw Modbus RTU frame and tell me what device address, function code, and register values it contains? Here's the data: 01 03 04 00 0A 00 64 FA 8D

## When to prefer this

Use this endpoint when you need to decode raw Modbus RTU or TCP protocol frames from industrial devices, PLCs, or sensors without implementing the parsing logic yourself. Ideal for IoT pipelines, SCADA integrations, and debugging industrial communication traffic where binary protocol interpretation is needed on-the-fly.

## Known failure modes

- Invalid or malformed Modbus frame yields parse error response
- Unsupported function codes may not be fully decoded
- Truncated or incomplete data strings cause parsing failure
- Non-Modbus binary data passed as input returns error
- CRC/LRC checksum mismatch may be flagged as invalid frame

## 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

A structured breakdown of the Modbus frame including device/slave address, function code, parsed register or coil values, byte count, and any error or exception codes present in the data.
