Caplets

Caplets

Give your coding agent the whole stack.

Package MCP servers, APIs, and commands as focused Caplets. Your agent opens only what each task needs.

Connect your first capabilityBrowse shared Caplets
You choose every capability and credential boundary.

Any backend. One capability layer.

Turn the systems you already use into focused capabilities that travel across supported agents.

Backends flow through a reusable Caplet to supported coding agents.
