Registries

Publishing (maintainers)

  1. Bump version in package.json
  2. 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
  3. Rebuild the MCPB bundle and run smithery mcp publish for Smithery
  4. 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
