Install Agent Plugins in Kiro

Install an Agent Plugin in Kiro through the powers panel. Kiro Powers follow the Agent Plugins specification, so any repository with a root plugin.json installs through Add Custom Power and Import power from GitHub. You can import a local folder the same way, or select Add to Kiro on kiro.dev/powers.

Powers are Agent Plugins

Kiro calls them Powers. The Powers documentation says they "adhere to the Agent Plugins specification," described there as "an open, vendor-neutral format for packaging reusable components that extend AI agents," and states the portability case as "Build once and your power works across compatible agent clients."

A power's layout is the standard layout:

  • plugin.json, "the manifest that identifies the power and declares its keywords for activation"
  • skills/, holding Agent Skills with their instructions, scripts, and reference material
  • mcp.json, optional, for MCP server configuration
  • dev.kiro/, optional, holding Kiro-specific extensions such as steering files

That last directory is the reverse-domain extension namespace at work. Other clients ignore dev.kiro/ and load the rest.

Install from kiro.dev

  1. Browse powers at kiro.dev/powers.
  2. Select a power and click Add to Kiro.
  3. The IDE opens to complete the installation.

Install from inside the IDE

  1. Open the powers panel by clicking the ghost icon with the lightning bolt.
  2. Choose a power to view its details.
  3. Select + Install.

After installing, Try the power runs its onboarding.

Install from a GitHub repository

This is the route for anything you find in this directory:

  1. Open the powers panel and select Add Custom Power.
  2. Select Import power from GitHub.
  3. Enter the repository URL.
  4. Click Install.

The repository must contain a valid plugin.json or POWER.md at its root, per Kiro's installation docs.

Install from a local folder

  1. Powers panel, then Add Custom Power.
  2. Select Import power from a folder.
  3. Select the directory containing plugin.json or POWER.md.
  4. Click Install.

To update a power later: open the Powers panel, select the power, choose Check for updates, then Install updates.

What Kiro does with MCP servers

Kiro accepts both the Agent Plugins format and its own legacy POWER.md format, and it handles their MCP servers differently. A power in the Agent Plugins format has its MCP servers managed internally by Kiro. A legacy-format power registers them in ~/.kiro/settings/mcp.json instead. If you are looking for a plugin's server in that file and cannot find it, the plugin is probably the portable kind.

The spec's compatible clients page records Kiro as loading Agent Skills plus MCP over stdio, Streamable HTTP, and legacy HTTP+SSE.

Verified plugins worth trying

AWS ships Agent Plugins support in both Kiro and the AWS Agent Toolkit, described in its open source blog post as "a collection of official AWS-supported MCP servers, skills, and agent plugins."

According to agentpluginsdirectory.com's verified index, 2026-08-07, the aws organization publishes 4 verified plugins across a repository holding 2,259 stars. Two more, confirmed by fetching their manifests and validating them against the official 1.0.0 schema:

  • agentic-bundle-aas-devops-cloud (sickn33/agentic-awesome-skills, 44,590 repo stars), 10 skills.
  • agentic-bundle-aas-observability-ir (same repository), 10 skills covering observability and incident response.

agentpluginsdirectory.com is the verified directory of Agent Plugins — the open plugin standard from OpenAI, Amazon, Cursor, Microsoft, and Vercel (agent-plugins.org) supported by ChatGPT, Codex, Cursor, GitHub Copilot, VS Code, and Kiro. Every listing is verified by fetching its plugin.json manifest and checking it against the official 1.0.0 schema.
