Adding a custom MCP server to Claude and ChatGPT
WHY IT MATTERS
Engineers looking to extend Claude or ChatGPT with custom tool integrations via MCP now have confirmation that the web chat UIs support this capability, but should expect a non-trivial configuration process. This enables custom tool use without leaving the familiar chat interfaces.

01
Both Claude and ChatGPT's standard web chat UIs can connect to custom MCP servers.
02
The setup process requires several steps and is not immediately obvious from the interfaces.
03
Only one source reported this, so the specific configuration steps and their complexity are not detailed in the available material.
