What is Caplets?
Caplets is a developer tool that optimizes how AI agents interact with MCP (Model Context Protocol) servers. Instead of dumping every tool and its full schema into the agent's context window, Caplets presents a small 'capability card' surface and progressively reveals tool schemas only when the agent requests them. This reduces token usage by up to 72% in benchmarks while completing the same tasks. It offers local and remote server modes (the latter centralizes auth for teams). The project is open source with an npm package and GitHub repository, targeting developers using agentic coding assistants like Claude Code, Codex, Pi, and OpenCode. No pricing or revenue model is currently visible, suggesting an early-stage, pre-revenue tool focused on solving a real prompt-engineering pain.
