Codex.

Codex reads MCP servers from ~/.codex/config.toml. The mcp-remote bridge makes OAuth and Streamable HTTP work everywhere.

OAuth

toml

[mcp_servers.plcs-ai]
command = "npx"
args = ["-y", "mcp-remote", "https://mcp.plcs.ai/mcp"]

The first run opens a browser to sign in; the token is cached for later runs.

API key

toml

[mcp_servers.plcs-ai]
command = "npx"
args = ["-y", "mcp-remote", "https://mcp.plcs.ai/mcp", "--header", "Authorization: Bearer plck_live_…"]

mcp-remote needs Node 18+ on your PATH. If your Codex version supports native remote MCP, you can instead set url = "https://mcp.plcs.ai/mcp" directly. Restart Codex after editing the config.
