What is an agent
capability runtime?
An agent capability runtime is a software layer that gives AI agents installable capabilities — such as image generation, video generation, image understanding, and video analysis — through a single interface. Instead of requiring agents to integrate separate SDKs, manage multiple auth flows, and learn different APIs for each capability, a capability runtime provides one install path, one auth flow, and one interface for everything. It sits between the agent and the capabilities it needs, abstracting away provider differences and letting agents focus on using capabilities rather than configuring them.
Early Access
AnyCap is currently in early access. Capabilities shown on this page are available to early access users. Request access on GitHub to get started.
Why it matters
AI agents are increasingly expected to do more than reason and generate text. They need to create images, produce videos, understand screenshots, analyze recordings, and interact with external systems. Each of these capabilities traditionally requires its own API integration, authentication, and error handling.
A capability runtime eliminates this fragmentation. Teams install one runtime, authenticate once, and every capability becomes available through the same interface — whether the agent runs in Claude Code, Cursor, Codex, or any other agent product.
How it differs from other approaches
| Approach | What it does | Trade-off |
|---|---|---|
| Direct API integration | Call each provider's API directly | Full control, but requires separate auth, error handling, and interface per provider |
| Tool integration platform | Connect to many third-party tools via SDK | Broad coverage, but still requires per-tool OAuth and SDK-level integration |
| Capability runtime | One install, one auth, every capability through a consistent interface | Agent-native, but capabilities are curated rather than open-ended |
| MCP (Model Context Protocol) | Standard protocol for agent-tool communication | Protocol-level standard, but each tool still needs its own MCP server |
AnyCap as a capability runtime
AnyCap is an agent-native capability runtime built from day one for agent workflows. It gives AI agents installable capabilities including image generation (Seedream 5, Nano Banana Pro), video generation (Veo 3.1), image understanding, and video analysis through one CLI and one interface. It works across Claude Code, Cursor, Codex, OpenCode, and OpenClaw.
