## Summary
Follow-up to #1145. When `mcpName` is set in `package.json`, it should
be the server name used by `mcp-publisher init`. Two issues addressed:
### 1. `getNameFromPackageJSON` mangled `mcpName` through npm-name
transformation
`mcpName` values are already in MCP server name format (e.g.
`io.github.foo/bar`). The existing code ran them through the
`@scope/name → io.github.scope/name` transform and its
`io.github.<your-username>/*` fallback, producing a broken double-prefix
result.
Example with `"mcpName": "io.github.acme/weather"`:
- Before: `io.github.<your-username>/io.github.acme/weather` ❌
- After: `io.github.acme/weather` ✅
### 2. `detectServerName` consulted git before `mcpName`
Even with `mcpName` set in `package.json`, a github.com git remote (or a
`repository` field) silently won — the function returned
`io.github.<owner>/<repo>` and never looked at `mcpName`. Per the
[quickstart
docs](https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/quickstart.mdx),
*"The value of `mcpName` will be your server's name in the MCP
Registry"*, so `mcpName` should take precedence.
## Changes
- `cmd/publisher/commands/init.go`:
- New `getMcpNameFromPackageJSON()` helper that returns `mcpName` or
`""`.
- `detectServerName` checks `mcpName` first, before git remote and the
`name`-based fallback.
- `getNameFromPackageJSON` simplified — the now-redundant `mcpName`
branch was removed; it only handles the npm `name` transformation.
- `cmd/publisher/commands/init_test.go` (new): 5 cases through the
public `InitCommand` API covering `mcpName` as-is, fallback to scoped
`name`, fallback to placeholder, version fallback, and `mcpName` winning
over a GitHub `repository` URL.
This completes the fix for #737.
## Test plan
- [x] `go test ./cmd/publisher/commands/` passes (5 new subtests)
- [x] `golangci-lint run ./cmd/publisher/commands/` clean
- [ ] Manual: `mcp-publisher init` in a git-tracked directory with
`package.json` containing `mcpName` produces a `server.json` whose
`name` matches `mcpName`, not the repo slug
