Custom MCP server

Anything that speaks the Model Context Protocol can be wired into CodeNow as a connector.

Add a custom MCP

1. Open the Connections sidebar tab
2. Click + Add Custom MCP Server
3. Enter:
   • Name — what it shows up as in the Connectors list
   • URL — the MCP server’s HTTP endpoint, OR
   • Command — for stdin/stdout MCP servers (mcp-server-foo --some-flag)
   • Auth — optional headers, env vars, or OAuth flow

The connector becomes available to the AI in this project.

Building your own MCP server

The Model Context Protocol is open. You can write a custom MCP server in any language. CodeNow’s Visual Tool Builder generates MCP-compatible tool files from a schema — see /tutorials/first-agent for that flow.
