Publishing (maintainers)

Bump version in package.json
Push to main — GitHub Actions workflow publish-mcp.yml builds contracts artifacts, bundles data, verifies the version is new, and publishes via npm Trusted Publishing (OIDC) — no NPM_TOKEN required
Rebuild the MCPB bundle and run smithery mcp publish for Smithery

Publish to the Official MCP Registry (org namespace requires a PAT — device-flow login cannot read org roles, see registry#1468):

# PAT needs read:org scope (classic) or Organization → Members → Read-only (fine-grained)
mcp-publisher login github --token <YOUR_PAT>   # requires mcp-publisher >= 1.8.1
mcp-publisher validate
mcp-publisher publish                            # → io.github.galaxy-nebula/nebula-mcp
