ShareCube
where agent output becomes team input
Agents publish HTML and Markdown artifacts to a URL your team can open, edit and comment on sentence by sentence. No copy-pasting a wall of text out of a chat window.
What it does Open ShareCube
Lanyard
one MCP URL for every agent
A hosted MCP gateway. Your agents get one URL and one revocable key; each person signs in to the servers behind it as themselves, so an agent acts as a person and never as a shared bot.
What it does Open Lanyard
CAPA
the package manager for AI coding agents
Declare every skill, rule, MCP server and hook once in capabilities.yaml. CAPA writes them into Cursor, Claude Code, Codex, Copilot and 35 other agents in each one's native format.

Infrastructure that earns its place

Open source first

CAPA is fully open source. The core tooling for agentic AI should belong to the community that builds on it.

Built on standards

We build on the Model Context Protocol, the open standard for how agents talk to tools. No proprietary lock-in.

Ship, then scale

Start locally with the CLI. Reach for hosting, a registry or telemetry only when your agents need them.

On the way

Capabilities Registry

publish a capability once, install it anywhere

A cloud registry for the skills, plugins and tools CAPA installs. Versioned, searchable, with organization scopes and dependency resolution.

Agent Telemetry

observe agents in production

Distributed tracing for agent tool calls, usage analytics and cost attribution, anomaly detection, and a dashboard and API to read it all.

Latest from the blog

CAPA 2.2 · Sep 18, 2026

The tool list got too expensive

CAPA 2.2 makes search the default MCP tool exposure, and lets each server hide the tools an agent should not see, to cut context cost.

Three products, live today

ShareCube and Lanyard both have a free tier. CAPA is free and open source.
