Add mpps.io — attestation for agent commerce

[fredxyt]

mpps.io provides cryptographic attestation for MPP transactions.

MPP receipts prove money moved. mpps.io proves what was delivered. It is the only service on this registry that serves the MPP ecosystem itself: every other service uses MPP to get paid, while mpps.io makes every MPP transaction more trustworthy.

After any MPP payment, either party can call mpps.io to attest what was exchanged, creating a complete evidence chain.

Details:

• Live API: https://api.mpps.io
• Free: 10 attestations/hour, 10 certified/day (no auth)
• Paid: $0.01/attestation via Stripe MPP
• HSM-signed (AWS KMS, FIPS 140-2 Level 3)
• 10-year immutable storage (S3 Object Lock, Compliance Mode)
• Open source: https://github.com/gdlg-ai/mpps.io (MIT)
• llms.txt: https://api.mpps.io/llms.txt
• Website: https://mpps.io

Built by GlideLogic Corp. (OTCQB: GDLG).

Validation:

• pnpm generate:discovery
• pnpm check:types
• pnpm check:ci (passes with existing noExplicitAny warnings)
• git diff --check

Thanks for submitting a service to the MPP directory!

If you want your service included in the curated mpp.dev/services list, complete this checklist before review:

Required

• Your service is live and accepting payments via MPP (not a placeholder or coming-soon)
• You've added your entry to schemas/services.ts following the contributing guide
• Types pass: pnpm check:types
• Build succeeds: pnpm build

Recommended

• Register your service on MPPScan (by Merit Systems) — it follows the standard MPP discovery format and makes your service discoverable by agents immediately, no PR required

Review criteria

We prioritize services that are high quality and novel. We may not approve services that duplicate existing functionality or aren't yet production-ready.
