Description
This PR introduces the
packcommand, enabling developers to package local MCP servers into distributable.mcpbbundles. It also extends theservecommand to seamlessly execute these bundles over the Nostr network.The implementation fully adheres to Anthropic's MCPB specification while extending it with a
_meta.com.contextvmnamespace to carry CVM-specific metadata (relays, public mode, encryption, etc.) without breaking compatibility with other hosts.Changes Made
src/pack/cvm-manifest.ts) to strictly type and validate the_meta.com.contextvmnamespace insidemanifest.json.cvmi pack: Introduced a new subcommand that packages a project directory into an.mcpbzip archive with maximum compression.cvmi packand no manifest exists, an interactive wizard prompts them for server details and CVM-specific defaults (relays, encryption mode) to generate a validmanifest.json.cvmi serve <bundle.mcpb>: Upgraded the serve command to accept an.mcpbfile. It extracts the bundle into a secure temporary directory, reads the custom metadata to override gateway defaults, and runs the server over Nostr.cli.tsand updatedAGENTS.mddocs.Verification
.git,.DS_Store, andnode_modules/.cachewhile preserving necessary dotfiles (dot: true).cvmi servecorrectly extracts the bundle, parses the CVM config, applies runtime overrides via CLI flags, and successfully exposes the server.pnpm type-checkwith 0 errors.
