Some people will push back on this. They are holding out hope that the recent improvements Anthropic has made in this regard have improved the context rot problem with MCP. Anthropic's changes improve things a little. But it is akin to putting lipstick on a pig. It helps, but not much.
The reason MCP is dying/dead is because MCP servers, once configured, bloat up context even when they are not being used. Why would anybody want that?
Use agent skills. And say goodbye to MCP. We need to move on from MCP.
MCP is a wire format protocol between clients and servers. What ends up inside the context window is the agent builder's decision.
The lipstick helps? This had me in stitches. Sorry for the non-additive reply. This is the funniest way I have seen this or any other phrase explained. By far. Honestly has made my day and set me up for the whole week.
