Add my server

Install Scholar RAG MCP in Codex

What you need first

  • Codex, installed.
  • uv, which gives the uvx command the server starts with.
  • Your own values for YOUR_SCHOLAR_RAG_CHAT_BASE_URL,YOUR_SCHOLAR_RAG_EMBED_BASE_URL,YOUR_SCHOLAR_RAG_RERANK_BASE_URL.

Steps

  1. Run this in a terminal. It writes the server into ~/.codex/config.toml, which the Codex CLI, its IDE extension and the ChatGPT desktop app share.
codex mcp add scholar-rag-mcp --env SCHOLAR_RAG_CHAT_BASE_URL=YOUR_SCHOLAR_RAG_CHAT_BASE_URL --env SCHOLAR_RAG_EMBED_BASE_URL=YOUR_SCHOLAR_RAG_EMBED_BASE_URL --env SCHOLAR_RAG_RERANK_BASE_URL=YOUR_SCHOLAR_RAG_RERANK_BASE_URL -- uvx scholar-rag-mcp==0.4.0
  1. Replace YOUR_SCHOLAR_RAG_CHAT_BASE_URL,YOUR_SCHOLAR_RAG_EMBED_BASE_URL,YOUR_SCHOLAR_RAG_RERANK_BASE_URL with your own values.
  2. Start Codex again and type /mcp: the server is listed.

Check it worked

Ask Codex: List the tools of scholar-rag-mcp.

If it does not start

spawn uvx ENOENT
uv is not on the PATH that Codex sees. Install it, or write the full path of uvx in the config.
The server starts, but its tools fail
A YOUR_… placeholder is still in the config, or its value is wrong.
