KeppyLab

AI-native capability management for MCP tool stacks.

describe helps an AI client discover MCP servers, install or register the right ones, write client configuration, and read the resulting capability map back as resources and prompts.

Why It Exists

AI clients are no longer just chat windows with a few tool buttons. They need a living map of capabilities: which tools exist, which are installed, which are safe to call, which need credentials, and which context resources can help the model choose the next action.

describe gives that map to the model.

What Changed

Registry-backed discovery

Search public MCP servers through the official Registry API, with local caching and a built-in offline starter set.

Resource-aware operation

Expose available and installed capability state as MCP resources so the model can inspect the stack before changing it.

Prompt-aware composition

Ship reusable prompts for composing lean agent stacks and reviewing MCP configuration risk.

Safer configuration

Back up config before edits, avoid inventing secrets, and register remote servers without unnecessary local installs.
