Troubleshooting

The connector doesn't appear or won't add
Make sure you pasted the exact address (https://mcp.letradalei.com/mcp) and that your assistant supports custom MCP connectors. In Claude, they live under Customize then Connectors, on both web and desktop.
Sign-in with Google didn't finish
Authorization opens in a popup or new tab. Allow popups for the assistant, complete the Google login, and return to the conversation. If it stalls, remove the connector and add it again.
The assistant isn't using the tools
On Claude, tools and skills both load based on your question, or type a skill directly, like /peticao. On ChatGPT, start your message with @Letra da Lei so the research tools load reliably, and name a skill directly, for example "using your peticao skill...", if you want a specific one. A vague task description on ChatGPT won't reliably trigger a skill.
It says it can't reach the server
Check your connection and that you're still signed in. If the problem persists, contact contato@letradalei.com.
