# Quantum Shield MCP

> Quantum Shield MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-15).

Processes data through a quantum-shield security or protection pipeline via a paid agentic endpoint

## Facts

- Endpoint: POST https://api.m2mcent.com/quantum-shield-mcp/api/process?utm_source=zero.xyz
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/quantum-shield-mcp-67b2fa45
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_iOUx6GQfFUqEGQCbDuhK9

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 quantum-shield-mcp-67b2fa45 -d '<json body>'
```

Example prompt: Run this payload through quantum-shield processing and return the secured result: 'sensitive-user-record-id-84729'

## When to prefer this

Choose this endpoint when you need to process or protect a data payload through a quantum-shield security pipeline in an agentic, pay-per-call context and do not have access to an in-house quantum-security library. It is particularly suited for agents that need lightweight, on-demand data shielding without managing cryptographic infrastructure.

## Known failure modes

- Empty or missing data field returns a validation error
- Malformed JSON input causes a 400 bad request
- Payment not provided or insufficient USDC balance results in a 402 payment required
- Service unavailable if the backend quantum-shield pipeline is down
- Overly large data strings may be rejected or truncated

## 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 processed output object based on the submitted data string, likely including a shielded or analyzed version of the input payload and any associated security metadata or status indicators.

## Response schema (JSON Schema)

{
 "type": "json",
 "example": {
  "success": true
 }
