LTP (Lazy Tool Protocol) – Reducing token usage for scalable AI agent tool access

Summary: LTP is a lightweight protocol that enables AI agents to access unlimited MCP tools by fetching tool schemas on-demand, significantly reducing token consumption and avoiding context bloat. It supports efficient scaling and secure execution of reusable workflows called Crafts.

What it does

LTP implements a Lazy Loading pattern to load tool schemas only when needed, cutting token usage by up to 93 percent compared to loading all tools upfront. It introduces Crafts, reusable workflows combining AI prompts with automation scripts, and enforces security via whitelists and sandbox restrictions.

Who it's for

Developers building AI agents that require access to large libraries of MCP tools without exceeding context window limits or degrading performance.

Why it matters

LTP solves token bloat by avoiding upfront loading of all tool schemas, enabling faster, cheaper, and more scalable AI agent operation.
