project
Zero-runtime-dependency Python CLI that sits between coding agents and MCP servers, keeping tool schemas out of the context window; 250KB install, 486 tests.
No evidence-backed relationships are recorded.
One measurement puts a 50-server tool catalog at 56 percent of a 128K context window before the first prompt. The per-server arithmetic is the part worth budgeting.
Reality
A developer measured 111,713 tokens of JSON schema from 10 MCP servers, injected before the first message, and priced the year at $1,764 per seat. The per-server number is the useful one.
Reality
A dev.to benchmark says one connector carries 42 percent of the schema load while supplying 3.7 percent of the tools. The direction holds. The money math does not.
Reality
One developer's count of a five-server Claude Code setup holds up where you can check it and drifts where you cannot. The checkable part is enough to change how you connect tools.
Reality
An engineering diary for a small MCP client puts numbers on schema bloat in the context window and on the roughly 950 hand-written lines it took to ship with zero dependencies.
