Summary
Nova works as a Claude marketplace plugin today, but it is not directly usable from Codex even when the MCP server is installed locally.
Current behavior
- Claude can load Nova from the marketplace and start the local MCP server through
.mcp.json.
- The installed Nova plugin includes a working MCP entry at
~/.claude/plugins/marketplaces/nova-marketplace/.mcp.json.
- The MCP server bundle exists locally at
mcp-server/dist/index.js.
- In Codex, the MCP server is not exposed automatically because Nova does not currently ship Codex-compatible plugin metadata.
Why this matters
Users who already installed Nova locally may expect it to be reusable in Codex, but today it appears disconnected even though the MCP server itself is present and runnable.
Expected behavior
Nova should be installable or discoverable in Codex without requiring users to manually copy plugin files into each workspace.
Suggested improvements
- Add Codex plugin manifest support, e.g.
.codex-plugin/plugin.json.
- Provide Codex-compatible MCP metadata so Codex can load the same Nova MCP server officially.
- Document a supported Codex installation path/workflow.
- Prefer a source-of-truth setup in the Nova repo itself rather than per-workspace local shims.
Notes
This looks less like an MCP-server problem and more like a packaging/distribution gap between Claude plugin format and Codex plugin format.
If helpful, I can follow up with a proposed file layout for Codex support.
