Let your AI install it

Claude ChatGPT Gemini Grok

Opens the chat with the message ready. You choose whether to send it; if it doesn't appear, paste this page's link.

/How to install

You need: Any Claude plan. The free plan allows 1 custom connector; on Team or Enterprise the organisation owner adds it first.

In claude.ai or the Claude app, open "Customize" → "Connectors".

Press "+ Add" and choose "Add custom connector".

Type a name you'll recognise, paste the URL below and press "Continue".

For authentication choose "No sign in", press "Continue" and then "Add".

https://declararfacil.com/api/mcp

Afterwards: In a chat, press "+" at the bottom left → "Connectors" and turn it on.

You need: A paid ChatGPT account: it may not be available on the free plan. ChatGPT now calls connectors "Plugins".

Go to chatgpt.com/plugins.

Press "+" and choose "Add custom MCP server".

Type a name and a description, and paste the URL below under "Connection".

Don't set up authentication. Accept "I understand and want to continue" and press "Create as a plugin".

https://declararfacil.com/api/mcp

Afterwards: In a new chat, type @ and pick the plugin.

You need: The Gemini app doesn't support custom connectors yet. It's done with Gemini CLI from the terminal, which needs a Gemini Code Assist license (it no longer has a free tier).

Install Gemini CLI if you don't have it yet.

In the terminal, run the command below.

Open Gemini CLI and type /mcp to check it shows up.

gemini mcp add --transport http -s user declararfacil 'https://declararfacil.com/api/mcp'

Afterwards: Ask as usual: Gemini will use the connector when it needs it.

You need: A Grok account. On Grok Business or Enterprise, an admin turns it on first.

Go to grok.com/connectors.

Press "New Connector" and choose "Custom".

Paste the URL below and save.

https://declararfacil.com/api/mcp

Afterwards: Grok will use the connector whenever your question needs it.
