CoreMesh Instant
Returns 402 requirements and protected JSON results.
Expose paid utility calls as tools in an MCP client.
CoreMesh Instant is the paid resource server. An MCP bridge runs on the buyer's machine, holds the buyer-controlled wallet locally, and calls the API through an x402 client.
Local MCP client
Exposes tools and handles x402 payment with the buyer's wallet.
MCP host
Calls the tools and receives structured results.
Security model
The buyer private key belongs in the local MCP bridge environment, not in CoreMesh Instant. Use a dedicated low-balance wallet and retain client-side spend controls.
The public GitHub package is a client template. It is not yet listed in the official MCP Registry; registry publication requires a separate npm publishing identity and registry authentication.
