Student Open-Sources MCP Gateway That Cuts Token Use 50% With Vector-Indexed Tool Catalog
randomdick_18 · reddit · 2026-09-06
A college freshman and former intern has released the open-source project justbetter-mcp: a custom gateway that sits between the client and MCP servers.
- How it works: All upstream MCP tools are indexed into a local vector catalog, and only tools relevant to the current task are surfaced to the model — the author reports roughly 50% fewer tokens than baseline.
- Usage: Works with existing code editors (VS Code, Antigravity, Claude Code, Cursor) or as a standalone TUI app, which the author finds works even better.
- Install: One command, npx justbetter-mcp; architecture diagrams and details are in the GitHub repo README.
