support for remote MCP servers

[nick-youngblut]

What feature would you like to see?

Trying to use a remote MCP server, such as the GitHub MCP results in the following error:

Error loading configuration: missing field `command`

command is not needed for remote MCP servers, so this shows that remote MCP servers are not supported, which is a big gap in capabilities for codex cli.

It would also be helpful to include an example in the MCP docs on how to configure a remote MCP server in the toml (why toml instead of json???).

Are you interested in implementing this feature?

Remote MCP servers are becoming more commonplace, as they should be

The following works for me

[mcp_servers.server-name]
command = "npx"
args = ["mcp-remote", "<remote_ip:port>", "--header", "<header>"]

@samarth-gupta can you provide a working example for an actual remote MCP, such as the official github MCP?

@nick-youngblut DeepWiki is a very popular remote MCP. It supports sse and http transport.

The following works for me [...] npx mcp-remote ...

From the mcp-remote github.

Note: this is a working proof-of-concept but should be considered experimental.

I'm unwilling to use experimental NPM packages in light of the recent supply chain attacks.

+1, not having out-of-the-box support for remote mcp servers e.g. streamable-http is a huge gap.

Codex should support remote mcp servers natively without relying on external libraries or scripts.

Most of the servers we're working on are now remote HTTP servers. Hopefully this is added soon!

Also seeking native support for remote mcp servers. Thank you!
