Connect Lovable to thirds.ai
Give this prompt to your AI agent. The agent does the task for you.
Read https://thirds.ai/docs/mcp/lovable and help me connect Lovable to thirds.ai with an API key
Use Lovable chat to build templates and create PDFs or images while you work. Create an API key on the API keys page first. Each successful PDF or static image costs one credit.
Install the server
Open Connectors, click +, and choose MCP server. Use these values:
| Setting | Value |
|---|---|
| Server name | thirds |
| Connection | Direct connection |
| Server URL | https://thirds.ai/mcp |
| Authentication | Bearer token or API key |
| Secret | YOUR_API_KEY |
Choose bearer token or API key authentication, not OAuth. Paste your thirds.ai API key. If the form asks for a header value, use Bearer YOUR_API_KEY. Click Add server. See Lovable's custom MCP guide.
This is a personal chat connector. It is not part of a published Lovable app, and it is not the Lovable MCP server at https://mcp.lovable.dev.
Check the connection
Ask Lovable to list the thirds.ai tools. You should see list_templates, render, and get_status.
Read the main MCP guide before you start paid work.
FAQ
Why is MCP server greyed out?
A workspace admin can turn custom MCP servers off. Use a workspace that allows custom MCP, or ask an admin to enable it.
Can my published Lovable app call thirds.ai this way?
No. Chat connectors only run while you build in Lovable. For a published app, call the thirds.ai API from your own server.
Does connecting spend credits?
No. Connecting and listing tools don't spend credits. AI template work and successful renders can. Ask your agent to show the action and the cost before it starts paid work.
