Connect every MCP server without paying the context-window tax.
Every server you connect dumps its full tool schema into context — used or not. Curating the toolset cuts tool-schema tokens by ~80% (7,476 → 1,497).

One source of truth
Write your servers once. Fold out to Claude, Cursor, VS Code, Windsurf, Zed — each in its own format.
Secrets as references
Configs carry ${env:…} / ${op:…} references, never values. Nothing sensitive is written to disk.
Drift-gated in CI
Commit the config to your repo and fail CI when a checkout drifts — standardize your team, no backend.
