I would argue that lot of the tools will be hosted on GitHub - infact, most of the existing repos are potentially a tool (in future). And the discovery is just a GitHub search
btw gh repos are already part of training the llm
So you don't even need internet to search for tools, let alone TEO
Security nightmare inbound...
The example given by Anthropic of tools filling valuable context space is a result of bad design.
If you pass the tools below to your agent, you don't need "search tool" tool, you need good old fashion architecture: limit your tools based on the state of your agent, custom tool wrappers to limit MCP tools, routing to sub-agents, etc.
