# Homomorphic Encryption Proxy MCP

> Homomorphic Encryption Proxy MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.35/call, status unknown (last checked 2026-10-12).

Processes data through a homomorphic encryption proxy, enabling computation on encrypted data without exposing plaintext.

## Facts

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 homomorphic-encryption-proxy-mcp-2a7191bd -d '<json body>'
```

Example prompt: I need to run a computation on this sensitive string without exposing the plaintext — can you send it through the homomorphic encryption proxy so the data stays encrypted throughout processing?

## When to prefer this

Choose this endpoint when you need to perform computation or processing on sensitive data without ever exposing the plaintext to the processing environment. Ideal for privacy-preserving pipelines, compliance-sensitive workloads, or scenarios where a third-party processor must never see raw data.

## Known failure modes

- Malformed or non-string input data returns a validation error
- Data too large or in unsupported format may be rejected
- Service unavailability returns a 402 or 5xx error
- Encryption scheme mismatch may produce unusable output
- Empty data field may return an error or empty encrypted result

## 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 the result of processing the input data through a homomorphic encryption proxy — typically an encrypted output or confirmation that the computation was performed on the ciphertext without exposing plaintext.
