MCP aggregation is one of the big differentiators

I'm curious, what issue does that solve? I'm only working on agents that make tool calls via HTTP in a home baked way but I can't imagine how resolving the tools from 2 MCP servers is harder than 1.

The issue is when you have many MCP tools the context becomes too large for the LLM. So Nexus indexes all the tools and lets you search for the right tool and then execute it.

Thanks, I think I get it now. In our case I've dealt with this problem by refactoring the monolithic agent into smaller agents, smaller, more specific prompts, fewer, more relevant tools.

We've found that monolithic agents just don't perform that well.

It looks like you're planning on monetizing this (which is totally fine!), do you have any plans on what the enterprise version would do differently?

And isn't OpenRouter already open source?

OpenRouter isn't open source that I know of, but there are open source things similar like Litellm.
