OneMCP merges 20-plus tool servers into three commands

OneMCP showed up on Hacker News on August 23 with a portal that replaces dozens of MCP tool definitions with three commands. Point it at your existing servers, 20-plus in the example given, and it exposes only search, describe and execute.

The stakes are cost and speed. Every MCP server wired into an agent adds tokens to its system prompt before a single request happens, and OneMCP claims the three-tool portal cuts that prompt by about 90%.

The mechanics matter more than the headline number. Instead of a model reading every tool's full schema on each call, it searches for what it needs, gets a description, then executes it. That's closer to writing code against an API than loading a full reference sheet into context every turn. OneMCP names Cloudflare's Code Mode portal as the pattern it's built on.

There's no pricing on the page. It's also a single source, so treat the 90% figure as OneMCP's own claim until someone benchmarks it.

Here's the tension worth watching. OneMCP is solving a problem that shouldn't need solving forever. MCP's own roadmap includes progressive discovery work aimed at the same context bloat, built into the protocol instead of wrapped around existing servers. If that ships and gets adopted, tools like OneMCP either fold into the spec or become redundant middleware.
