Making MCP context cost visible before the agent sees it feels like a useful debugging tool, not just an optimization.

How does it work? Im building a video editor and right now it has access to nearly 100 tools. Would be good to learn the techniques you used to make tool discovery more efficient.

The readme has some examples for what it does. It doesn’t list the entire schema (noisy). Instead it uses shorthand. Perhaps a sufficiently smart agent can do this.

Cool! Can we get a human-efficient MCP CLI while at it? I want to be able to use MCP just as well as the LLMs can.

I thought Codex and Claude Code agents are already token-efficient so writing agents that saves tokens is pointless.

I don't know about Codex, but Claude Code defers loading tools if their definitions exceed 10% of the context, https://code.claude.com/docs/en/mcp#how-it-works.

Are they though? Will they always be? Is it in their interest to be efficient?

Sorry, isnt this just compression? Lookups burn tokens just on the other end?

I really think we’ve missed a trick using JSON instead of SExpressions as the default marshaller for AI tool use.

I really doubt that null and \n make any sense to replace with non ascii symbols. They are both most likely already a token only and for other purposes at least \n becomes larger as a symbol.
