#42How is this different from headroom? Mcptoon seems like it's specific to tool calls. https://github.com/headroomlabs-ai/headroom

Re: Show HN: Mcptoon – Token-efficient MCP CLI client
#44I like the idea, but this seems a little too aggressive, JSON (287 tokens) — what every other MCP client returns:
~~~
[
{"name": "search_web", "description": "Search the web for information",
"inputSchema": {"type": "object", "properties": {"query": {"type": "string", "description": "Search query"}, "num_results": {"type": "number", "default": 5}}, "required": ["query"]}},
{"name": "fetch_url", "description": "Fetch content from a URL",
"inputSchema": {"type": "object", "properties": {"url": {"type": "string"}}, "required": ["url"]}}
]
TOON (5 tokens) — what mcptoon returns:
search_web fetch_url

#45Somewhat related to this project, I'm surprised that not all harnesses are using something like CodeMode for MCPs.
Been experimenting with it in the OpenCode V2 beta and it's pretty great. The combination of tool search, call chaining and field projections feels just right and saves a lot of context. LLMs are good at writing code, who would have thought that?

#47Q: aren't models trained to message templates using JSON for tool calls. Would a model inherently struggle with a different format?
Q: is there a measurable difference compared to harnesses with tool search?

Re: Show HN: Mcptoon – Token-efficient MCP CLI client
#49I made an MCP proxy with a similar idea in the past: replace a ton of tools that consume tokens with just two (get_tool_schema, invoke_tool) - https://github.com/ameshkov/mcp-compress-router One thing that I noticed is that it’s often better to return tool names with argument names, i.e. return “search_web(query)” instead of just “search_web” when listing tools. Otherwise models often tend to hallucinate argument nam…
