A few setup details.
Choose the connection that fits your client and environment.
Can I paste a JSON configuration?
This format is used by Cursor and some compatible clients. VS Code, Windsurf, Gemini CLI, and OpenCode use different fields—choose their setup above.
{
"mcpServers": {
"molar": {
"url": "https://api.molar.it/mcp"
}
}
}Which URL goes in my client?
Use https://api.molar.it/mcp as the server URL. mcp.molar.it is this setup page.
Can the hosted browser reach localhost?
A hosted browser cannot reach your computer’s localhost directly. Use a reachable preview URL, or follow the local execution setup in the CLI guide.
What if sign-in or tool discovery fails?
Check that your client supports remote MCP and that its settings use the exact server URL above. Finish or retry the client’s sign-in flow, then refresh its tool list. Workspace administrators may restrict custom MCP connections.
