Orca skills registry & MCP

Orca CLI commands are distributed as skills — versioned packages an agent can install into its own skill directory.

Installable Orca skills

Use npx skills add with the public Orca repo and the skill name. The default agent setup uses orca-cli, computer-use, and orchestration; install orca-emulator only when agents need to drive a local iOS Simulator from Orca.

Skill	Install	Use it for
orca-cli	npx skills add https://github.com/stablyai/orca --skill orca-cli	Orca-managed worktrees, terminals, files, automations, and the built-in browser.
orchestration	npx skills add https://github.com/stablyai/orca --skill orchestration	Structured multi-agent coordination with messages, tasks, dispatches, and decision gates.
computer-use	npx skills add https://github.com/stablyai/orca --skill computer-use	Desktop app control through accessibility trees, screenshots, clicks, typing, and safe UI actions.
orca-emulator	npx skills add https://github.com/stablyai/orca --skill orca-emulator	iOS Simulator control from Orca with taps, gestures, typing, permissions, camera injection, and accessibility.

orca-cli

npx skills add https://github.com/stablyai/orca --skill orca-cli

After install, your agent has a SKILL.md describing every Orca CLI command — worktree, terminal, and browser.

orchestration

npx skills add https://github.com/stablyai/orca --skill orchestration

Use this when an agent should coordinate other agents through orca orchestration messages, tasks, dispatches, and worker completion tracking. See Orchestration for the workflow.

computer-use

npx skills add https://github.com/stablyai/orca --skill computer-use

Use this when an agent needs to inspect and operate local desktop app windows through Orca's computer-use surface. See Computer use for the workflow.

orca-emulator

npx skills add https://github.com/stablyai/orca --skill orca-emulator

Use this when an agent should control an iOS Simulator from inside Orca through orca emulator commands.

Add your own skills

Any repo with a skills/<name>/SKILL.md file can be installed via npx skills add. Point your agent at internal repos to give it company-specific powers.

MCP servers

Orca supports Model Context Protocol servers for agents that speak it. Register MCP endpoints under Settings → Integrations → MCP. MCP servers show up as tools inside the agent CLI that consume them.
