Nomina v1.3.0

v1.3.0 adds a Streamable HTTP mode and a published container image, so Nomina can be hosted behind a URL instead of launched per client. The stdio transport and the Claude Desktop extension are unchanged; tools are identical to v1.2.0.

What’s new

• server.py --transport streamable-http serves MCP at /mcp (stateless, JSON responses) and a liveness probe at /healthz. --host, --port (or PORT), and --public-host (or PUBLIC_HOST) configure binding; DNS-rebinding protection rejects requests addressed to any other hostname with HTTP 421.
• Container image ghcr.io/nomina-xyz/nomina-mcp (linux/amd64 and linux/arm64), listed in the MCP Registry as a second package alongside the .mcpb bundle.
• Releases are now built and published by a tag-triggered GitHub Actions workflow, which attaches the bundle to the GitHub release and publishes to the MCP Registry through OIDC.

Install

• Claude Desktop: download Nomina.mcpb from the release and install it via Settings → Extensions → Advanced settings → Install Extension.
• Claude Code or any stdio client: uv run --frozen --no-dev --directory <clone> server.py.
• Gemini CLI: gemini extensions install https://github.com/nomina-xyz/nomina-mcp.
• Self-hosted: docker run --rm -p 8000:8000 ghcr.io/nomina-xyz/nomina-mcp:1.3.0, then connect a Streamable HTTP client to http://localhost:8000/mcp. See Install → Self-hosted.

Limits

Yahoo Finance’s public endpoints can be delayed, incomplete, or rate limited, and its terms restrict automated collection and redistribution — see Data sources and limits. No public Nomina endpoint is operated yet; remote connectors for ChatGPT, Perplexity, and Copilot Studio need one and remain pending until it exists.
