You’ll run Glider as a local HTTP server. Make sure glider is available on PATH.

# bash/zsh
export PATH="$PATH:$HOME/.dotnet/tools"
which glider

Codex currently supports MCP servers over Streamable HTTP. Start Glider in HTTP mode (default endpoint: http://localhost:5001/mcp). Add --verbose for logs if needed. Use --default-timeout to raise the 20 minute server-side timeout for larger solutions.

glider --transport http --default-timeout 30m

Edit: macOS/Linux ~/.codex/config.toml, Windows %USERPROFILE%\.codex\config.toml. Codex does not currently support per-repo MCP config, so this is user-scoped. Codex docs: developers.openai.com/codex/mcp.

# ~/.codex/config.toml
[mcp_servers.glider]
url = "http://localhost:5001/mcp"
tool_timeout_sec = 1200

Start a new Codex session, then run /mcp to confirm the server is available.

codex
# Then run: /mcp
