# PID Loop Tuner MCP

> PID Loop Tuner MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.12/call, status unknown (last checked 2026-09-15).

Tunes PID (Proportional-Integral-Derivative) control loop parameters for industrial or embedded control systems given process data.

## Facts

- Price: $0.12/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 pid-loop-tuner-mcp-72b4d6a6 -d '<json body>'
```

Example prompt: Can you tune my PID loop? Here's the process step-response data: the system has a gain of 2.5, time constant of 8 seconds, and dead time of 1.2 seconds — I need Kp, Ki, and Kd values to minimize overshoot.

## When to prefer this

Choose this endpoint when you need automated PID parameter calculation from process data without manually applying Ziegler-Nichols or other tuning methods. Particularly useful in agentic control system workflows where a quick, paid API call replaces manual engineering calculation.

## Known failure modes

- Malformed or insufficient process data string returns an error
- Unstable or non-minimum-phase process data may yield unreliable gains
- Missing required 'data' field causes a 400-level validation error
- Payment failure or insufficient USDC balance blocks processing via x402

## 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 computed PID gain values (Kp, Ki, Kd) and/or tuning recommendations derived from the submitted process data, enabling the user to configure their controller for stable and optimized closed-loop performance.
