Add a custom connector in Claude Code
Claude Code adds a custom connector with one command in your terminal. These steps use Humble as the example.
You need the tool’s address
Each tool gives you its own connector address. It starts with https://. In your terminal. For Humble, the address is:
https://my.humbleai.com/mcpAdd it in Claude Code
Step 1: Run the command
In your terminal, run this command. For another tool, change humble to a short name for it, and the address to its address:
claude mcp add --transport http --scope user humble https://my.humbleai.com/mcpStep 2: Open /mcp and choose the tool
In Claude Code, type /mcp and choose the tool, such as humble.
Step 3: Sign in and select Allow
Sign in to the tool in your browser and select Allow. Some tools call it an unverified app, because they cannot check who made it. That is expected.
Allow an unverified app to use your Humble account?--scope user makes the tool work in every project. Leave it out to add it to this project only.
