Integration with Claude Desktop

No installation:
{
"mcpServers": {
"codex-data": {
"command": "npx",
"args": ["-y", "@codex-data/codex-mcp"],
"env": {
"CODEX_API_KEY": "<your-codex-api-key>"
}
}
}
}
Local installation:
{
"mcpServers": {
"codex-data": {
"command": "node",
"args": ["/path/to/codex-mcp/build/index.js"],
"env": {
"CODEX_API_KEY": "<your-codex-api-key>"
}
}
