Adding a custom MCP server to Claude and ChatGPT
Custom MCP servers can connect to Claude and ChatGPT chat interfaces but require many steps
“Connecting a custom MCP server to Claude and ChatGPT's standard chat interfaces is possible, but can take quite a few steps.”
Simon Willison published a TIL documenting how to connect a custom MCP server to both Claude and ChatGPT's standard chat interfaces. The post highlights that while the integration is achievable, it involves a non-trivial number of configuration steps. This is a practical developer note rather than a major announcement, but reflects growing real-world MCP adoption beyond dedicated tooling.
