More MCP tools will just make your agent worse.
When your MCP has hundreds of tools to choose from it becomes a liability.
The model has to read every tool definition. Choose the right one, pass the right inputs, and not blow up the context window before the work even starts.
The better pattern isn't giving the agent more choices. It's giving it a cleaner way to find the right one.
Instead of giving the agent hundreds of preloaded tools, give it a smaller interface: search what exists, write the code, then execute the right call.
