Agent Plugins v1

Qwen Code natively loads portable Agent Plugins v1 packages. The package keeps its standard plugin.json, mcp.json, and SKILL.md files: installation does not generate qwen-extension.json or rewrite portable files.

Use the existing extension commands with a local directory, link, archive, Git repository, archive URL, or scoped npm package:

bash

qwen extensions install ./my-agent-plugin
qwen extensions link ./my-agent-plugin
qwen extensions install owner/my-agent-plugin

The root manifest must target the canonical v1 schema:

json

{
  "$schema": "https://agent-plugins.org/schemas/1.0.0/plugin.schema.json",
  "name": "my-agent-plugin",
  "version": "1.0.0"
}

Supported capabilities

Capability	Support
Direct-child `skills/*/SKILL.md`	Yes
stdio MCP servers	Yes
Streamable HTTP MCP servers	Yes
Legacy HTTP+SSE MCP servers	No; the entry is skipped
Commands, agents, and hooks	No; these directories are ignored
Qwen context, settings, channels, and apps	No
`extensions.*` client namespaces	No; unimplemented namespaces are ignored

Skills follow the Agent Skills specification. An invalid skill is skipped without disabling valid sibling skills. The experimental allowed-tools field is recognized as a string but does not grant pre-approved Qwen tools.

For stdio MCP servers, Qwen Code expands ${PLUGIN_ROOT} and ${PLUGIN_DATA} once in args, environment values, and cwd. PLUGIN_DATA is a writable per-installation directory whose contents persist across updates and reinstall. Remote MCP endpoints must use HTTPS, except for loopback HTTP endpoints.

Agent Plugins v1 is a package format, not a marketplace integration. Install packages through Qwen Code's existing extension sources.
