KillionApps Promotion Allocation v0.5.0 is now listed as active/latest in the official MCP Registry, and I’m looking for a small number of independent developer and ecommerce-operator pilot participants.

What it does: it evaluates a product portfolio and returns a constrained promotion-budget allocation aimed at expected incremental contribution profit.

The free pilot requires no account and no payment credential. It checks Registry discovery, canonical machine metadata, the public quote and schema, free validation, and a signed redacted receipt. The receipt is Ed25519-signed and can be verified locally; it excludes the raw portfolio and product names.

Important boundaries:

• The decision route is priced at $5 USD, but Stripe remains in test mode and live payments are disabled.
• Performance status is UNVALIDATED_FORWARD; the pilot does not claim demand, causal lift, or realized profit.
• The current decision model is v0.3.0.
• The service has no advertising-account access and grants no execution authority.
• Participants should submit only the signed receipt and bounded feedback—never the raw portfolio.

Feedback on discovery, schema clarity, MCP handshake behavior, receipt verification, and operator usability would be especially useful.
