name: Publish to MCP Registry

# Publishes server.json to the official MCP Registry (registry.modelcontextprotocol.io),
# which the GitHub MCP Registry (github.com/mcp) syncs from.
#
# Run this AFTER the PyPI package and GHCR image for the release exist — the registry
# validates both artifacts at publish time:
#   1. Tag + GitHub release        -> Docker image published to GHCR (release-docker.yml)
#   2. Run "publish" workflow      -> package published to PyPI (publish.yml)
#   3. Run this workflow           -> server published to the MCP Registry
