ContextVM Payments (CEP-8)

Use this skill when you want ContextVM servers to charge for specific capabilities and clients to pay automatically using the TypeScript SDK payments layer.

Payments are implemented as middleware around transports:

• Server-side middleware gates priced requests: it must not forward to the underlying MCP server until payment is verified.
• Client-side middleware listens for payment notifications, executes a handler, then continues the original request.

This skill documents how to use the SDK payments layer. For transport setup (signers, relays, encryption), see:

• ../typescript-sdk/SKILL.md
• ../server-dev/SKILL.md
• ../client-dev/SKILL.md

Quick start: charge for one tool (server + client)

Server: price a capability and attach payments
