Questions

What is an MCP server?

The Model Context Protocol is an open standard, introduced by Anthropic in November 2024, for connecting AI apps to tools and data. An MCP server exposes tools, resources and prompts that any MCP client can use, including Claude Code, Codex, Cursor and ChatGPT.

Can you make money from an MCP server?

Yes, when the server is the front door to a paid service. Remote MCP servers support OAuth, so you can require an account and meter usage per key, the same way a normal API does.

What is the easiest MCP servers idea to start with?

Agent-to-agent chat bridge: A shared channel where Claude Code and Codex pass work to each other instead of you copy-pasting. It is sized at 1 to 2 weeks, and the threads behind it have 2.3k upvotes.
