Add UV as a new server type for Python extensions that use UV runtime
for dependency management instead of bundling dependencies.
Schema changes (v0.4):
- Add "uv" to server.type enum
- Make mcp_config optional (not needed for UV type)
- UV extensions rely on pyproject.toml for dependencies
Documentation:
- Add UV runtime section to MANIFEST.md explaining benefits and usage
- Update README.md to recommend UV runtime for Python
- Add complete hello-world-uv example
Benefits of UV runtime:
- Cross-platform support (Windows/macOS/Linux, Intel/ARM)
- Small bundle size (~100 KB vs 5-10 MB)
- Handles compiled dependencies portably
- No user Python installation required
Example manifest:
{
"manifest_version": "0.4",
"server": {
"type": "uv",
"entry_point": "src/server.py"
}
}

Remove the concept of "vLatest" throughout the codebase to encourage use of McpbManifestAny which supports all manifest versions. Changes include:
- Delete src/schemas/latest.ts and src/schemas_loose/latest.ts
- Remove vLatest and latest-related exports from schema index files
- Remove McpbManifestLatest type, replace McpbManifest to point to McpbManifestAny
- Remove LATEST_MANIFEST_VERSION, LATEST_MANIFEST_SCHEMA constants
- Update all main export files (index.ts, cli.ts, node.ts) to export from 0.3.js instead of latest.js
- Update tests to use v0_3.McpbManifestSchema explicitly
- Add @deprecated annotation to McpbManifest directing users to McpbManifestAny
This encourages better version compatibility by using the union type that supports all manifest versions rather than assuming a single "latest" version.

- Add schemas/latest.ts and schemas_loose/latest.ts as aliases to current version
- Update constants.ts to use latest.ts instead of hardcoded version imports
- This makes version updates easier - only need to update latest.ts pointer
- Create src/schemas.ts to re-export from schemas/index.ts for test imports
- Update test manifests to use manifest_version "0.2" instead of "1.0" or "1.0.0"
- Fix import sorting and formatting issues in schema files
- Export McpbManifestSchema from schemas/index.ts
- Move schemas.ts and schemas-loose.ts into separate versioned folders
- Create schemas/0.1.ts and schemas/0.2.ts for strict validation
- Create schemas_loose/0.1.ts and schemas_loose/0.2.ts for loose validation
- Add index files to export all historical schema versions
- Update all imports to use schemas/0.2.ts
- Enforce exact version values using z.literal() for both v0.1 and v0.2
- Remove dxt_version support from v0.2 schemas
- Remove all passthrough() from v0.2 strict schemas
- Validate privacy_policies as URLs in v0.2
