ContextVM

ContextVM is a decentralized protocol that enables Model Context Protocol (MCP) servers and clients to communicate over the Nostr network. It uses Nostr as a secure, distributed transport layer—leveraging cryptographic keys for identity, decentralized discovery, and Bitcoin-powered micropayments. Rather than relying on centralized infrastructure like domains, OAuth, or cloud hosting, ContextVM allows anyone to run or access services using only Nostr and a internet-connected device. It transforms any computational service into a discoverable, accessible, and monetizable resource—while preserving privacy, security, and user sovereignty.

It is shipping time! 🚀 cvmi v0.4.0 is out!

The ContextVM CLI now speaks CEP-8 payments natively. Priced capabilities are first-class in the CLI:

💳 See prices upfront — cvmi call now shows advertised per-tool prices and accepted payment rails right in the tool list and --help.

🔀 Two payment modes:

transparent (default for call) — PMI-agnostic settlement, the server picks the rail.
explicit_gating — priced tools surface a clean Payment Required error with payment options. Pay one, retry, done. Now the default for cvmi use, so agent hosts over stdio get explicit signals instead of silent notifications.

🛡 Spec-hardened parser — malformed cap prices (negative values, out-of-order ranges) are now rejected per CEP-8, not coerced into bogus ranges.

⚙ cvmi serve gained payment interaction config.

Plus bumps to @contextvm/sdk ^0.13.9 and @modelcontextprotocol/sdk ^1.29.
