> Sure, you could dump all the documentation into context for code generation, but that often requires more context than interacting with an MCP tool.

MCP works exactly that way: you dump documentation into the context. That's how the LLM knows how to call your tool. Even for custom stuff I noticed that giving the LLM things to work with that it knows (eg: python, javascript, bash) beats it using MCP tool calling, and in some ways it wastes less context.

YMMV, but I found the limit of tools available to be <15 with sonnet4. That's a super low amount. Basically the official playwright MCP alone is enough to fully exhaust your available tool space.



Ive never used that many. The LLM performances collapse/degrade significantly because of too much initial context? It seems like MCP implems updates could easily solve that. Like only injecting relevant servers for the given task based on initial user prompt.

The playwright MCP alone introduces 25 tools into the context :(
