examples/hello-world-uv fails to pack

[marklemay]

Describe the bug
mcpb pack on the example fails

To Reproduce

PS F:\mcpb> mcpb pack examples/hello-world-uv
Validating manifest...
ERROR: Manifest validation failed:

  - server.mcp_config: Required
ERROR: Cannot pack extension with invalid manifest

Seeing the same issue with @anthropic-ai/mcpb@2.1.2.

The docs say server.type = "uv" can omit server.mcp_config, but the published v0.4 schema/validator still requires it, so mcpb validate and mcpb pack fail with:

server.mcp_config: Required

Workaround for now is adding a redundant mcp_config block, looks like a docs/schema mismatch.

#181 and #206

This is addressed in PR #206 which adds the required mcp_config block to the hello-world-uv example. As a workaround until that merges, you can add an mcp_config block to the manifest:

"mcp_config": {
  "command": "uv",
  "args": ["run", "--directory", "${__dirname}", "src/server.py"]
}

The v0.4 schema requires mcp_config for all server types including UV. The example and docs were out of sync with the schema — PR #206 fixes both.

This is fixed — PR #206 merged on April 5, which adds the required mcp_config block to the hello-world-uv example. The updated example packs cleanly with mcpb pack. Thanks for reporting.
