fix: reject mangled publisher metadata (#1310)
## Summary
- add a publisher preflight that rejects non-UTF-8 `server.json` bytes
before parsing
- reject unpaired UTF-16 surrogate escapes inside JSON string fields
before publish/validate requests are sent
- keep valid non-ASCII descriptions, including em dashes, round-tripping
through the publish path
- make the publisher test token helper set `USERPROFILE` as well as
`HOME` so Windows tests use the temp home directory

Closes #1306.

## To verify
- `go test ./cmd/publisher/commands -run
"TestPublishCommand_(Success|PreservesNonASCIIDescription|RejectsInvalidUTF8ServerJSON|RejectsUnpairedSurrogateEscape)$"
-count=1`
- `go test ./cmd/publisher/commands -run TestPublishCommand -count=1`
- `go test ./cmd/publisher/commands -run TestValidateCommand -count=1`
- `git diff --check`

MCP Publisher Tool - Development

CLI tool for publishing MCP servers to the registry.

These docs are for contributors. See the Publisher User Guide for end-user documentation.

Quick Development Setup

# Build the tool
make publisher

# Test locally 
make dev-compose  # Start local registry
./bin/mcp-publisher init
./bin/mcp-publisher login none --registry=http://localhost:8080
./bin/mcp-publisher publish --registry=http://localhost:8080

Architecture

Commands

  • init - Generate server.json templates with auto-detection
  • login - Handle authentication (github, dns, http, none)
  • publish - Validate and upload servers to registry
  • status - Update server lifecycle status (active, deprecated, deleted)
  • logout - Clear stored credentials

Authentication Providers

  • github - Interactive OAuth flow
  • github-oidc - CI/CD with GitHub Actions
  • dns - Domain verification via DNS TXT records
  • http - Domain verification via HTTPS endpoints
  • none - No auth (testing only)

Signing Providers

Optional: enables dns and http methods to sign out-of-process without direct access to the private key.

  • google-kms - Google KMS signing
  • azure-key-vault - Azure Key Vault signing
