every MCP server you connect loads its tool definitions into your context window. name, description, parameter schema, all of it. connect 10 servers with 5 tools each and you've burned 50 tool definitions worth of tokens before your conversation even starts.

I see the exactly problem while using the XcodeBuildMCP, Cloudflare's Code Mode might be a better solution which only expose search and execute while consuming only around 1,000 tokens.
